Disastrous Fish Kill in the Turners Falls Power Canal

Posted by on 06 Oct 2015 | Tagged as: 5-year FERC licensing process, GDF-Suez FirstLight, Turners Falls power canal, US Geological Service’s Silvio O. Conte Anadromous Fish Lab

On Monday, October 5, 2015, GDF-Suez FirstLight Power drained the Turners Falls Power Canal for dredging in its annual “drawdown.” For many months out of the year all of the Connecticut River’s migratory and resident fish are forced into the power canal while the 2-1/2 miles below Turners Falls Dam is left virtually empty.This happens annually, and the related mortality has yet to be fully studied, even though the USGS Silvio O. Conte Anadromous Fish Research Center overlooks the TF Power Canal.

These few photos below are just a tiny sample of a 20-minute walk through a small segment of the canal at 7:00 a.m. on the day the canal drained. Thousands of fish lay struggling, stranded, and dead in the drying pools.Click on photos to enlarge.

May 23, 2015. Turners Falls, MA. The test flows at Turners Falls Dam are now tamped down to 2,500 cubic feet per second. Thus anglers had given up fishing the riverbed below the dam yesterday(Friday) morning. However, the head gates beside the dam were open, releasing water at a good clip to course down the Turners Falls Power Canal. With little flow moving fish upstream in the actual river, it is commonly accepted knowledge that this forces fish to default to where they will find stronger upstream current to attract them. In this case that means a place 2-1/2 miles back downstream in the Dead Reach–the terminus of the canal at Cabot Station, where the power company dumps the river back into… the river. Thus, the canal becomes the impoverished, default habitat for migratory fish, attracted via privately- controlled flows that can be manipulated by dam operators. Thus, on Friday, just down from those head gates was the place where a few anglers gathered to fish the canal–just down the paved path to the low bridge behind the Great Falls Discovery Center.
P1000416
These gents were fishing shad that are part of the US Fish & Wildlife Service and the Connecticut River Atlantic Salmon Commission’s 1967 fisheries restoration mandate to move migratory fish upstream into New Hampshire and Vermont–to create a source of “seafood” for the public. These American shad, in Latin Alosa sapidissima–or “most delicious herring” were going to be eaten.
P1000417
With the main attraction flow coming from the downstream end of the power canal, it was primarily company flow through that conduit that was affecting upstream fish movements. Friday morning that flow was facilitating good numbers of fish in the viewing windows at Turners Falls Dam. The public’s fish and river should never be left in the private control of a corporation. That situation has resulted in the Black Hole of fish passage all these decades: the fish never reach Vermont and New Hampshire, and no one knows their fate after all upstream migrants are forced to enter the Turners Falls Power Canal.
A mile and a half downstream, there were two other potential anglers–perched in a cottonwood above the partially-flowing Connecticut’s riverbed. At just 2,500 cfs, they may have been licking their lips over fish that were confused or slowed and turning back in the river due to the withering upstream current. Slowed or stalled fish make for good eagle forage.
P1000425
Another half mile on down the river fishermen at The Rock Dam Pool were also happy to try and take advantage of a slowed or confused migration at this ancient site. Looking down from the rock ledge at the head of the pool, shad could be seen streaming through the water just 10 feet out. They moved by in tens and fives and dozens, but there was no way to discover whether they were milling through the edges of that frothy pool and simply returning to be seen again in an endless circling, or whether they were trying to shoot through one of the upstream notches in flows that were diminished by reductions at the dam.P1000433P1000432
Lastly, on “Migratory” Way, just down the canal past the USGS Conte Anadromous Fish Research Center, a crew of Conte fisheries people were inside FirstLight’s gates at the Cabot Hydro Station on the canal. USGS and the power company owners of the canal have been very close friends for decades now. Lab staff have worked for years on endless canal studies subsidized by Northeast Utilities, then NGS, and–of late, GDF-Suez FirstLight. Funny, though USGS holds the only National Marine Fisheries Service permit to study federally endangered shortnose sturgeon right here on the Connecticut, no study or tagging of sturgeon was done at all this year at their only documented natural spawning site–the Rock Dam Pool, just yards away from Conte Lab. And this, in a critical year of FEDERAL RE-LICENSING STUDIES.
P1000442
The folks in this picture are likely doing studies on migrating American eels. Power companies tend not to mind this type of work–as eels are difficult to study, they don’t spawn in the Connecticut River and thus are not an angler concern, and putting in “eelways”–which are wonderfully inexpensive, is a dirt cheap way to look “environmental” in the marketplace. Just as USGS Conte staff did endless canal studies with corporate study cash for decades on the TF Canal, they may be embarking on yet another cozy partnership, where years of data collection can be corporately subsidized, while true flows and fish passage upstream in the broken Connecticut River ecosystem through the Dead Reach here–and north past the Northfield Mountain Pumped Storage Station, gets ignored.

In mid-December I was interviewed on Greenfield Community Television’s Local Bias feature by Mark Wisniewski, former Greenfield City Council President. In a wide-ranging talk we discussed my experiences with the ongoing Federal Energy Regulatory Commission licensing process as both a journalist and stakeholder in the hydro projects at Northfield Mountain and the Turners Falls Power Canal on the Connecticut River. The FERC licensing process is a cumbersome and lengthy ordeal–transpiring over a 5- year swatch of time.

Anyone interested in–or involved as a citizen in, the deluge of FERC projects currently affecting our region, might gain some insight by tuning in: from fracked-gas pipelines, to hydro, nuclear, climate and ecosystem impacts.

The current Federal Energy Regulatory Commission Re-licensing process for FirstLight Power’s Turners Fall/Cabot Station and Northfield Mountain Pumped Storage Stations represents the last chance the Connecticut River gets to recover some of its biodiversity, fecundity and ecosystem functions for many decades to come. A second failure by the public agencies charged with protecting the public’s fisheries resources and endangered species will likely close off–forever, the last, best chance to restore New England’s Great River.

Will the federal and state agencies responsible for protecting and guiding the migratory fisheries restoration since 1967 (USFWS, National Marine Fisheries Service, VT, NH, and MA Division of Fish & Wildlife), again steer migratory fish headed upstream to northern MA, VT and NH spawning habitats into a private “roach motel” of deadly hydro blades and muck? Or, will they bring them directly upstream to a fish elevator at the Turners Falls and redeem decades of failure? Get the low-down, and hear about viable alternatives in this half-hour interview.

River Science Dead Ends….Again

                          River Science Dead Ends…Again

Since 1980 it’s been clear the Turners Falls power canal is a dead end for the Connecticut River’s American shad migration.  Thirteen years of federal fish research in that watery rabbit hole only serves to reinforce the point.    

A Federal Energy Regulatory Commission inquiry of US Geological Survey Conte Fish Lab researchers in Turners Falls, MA, found that it takes a radio-tagged American shad an average of eight days to swim the 2-1/2 miles from the end of the Turners Falls power canal to an area near the dam.  A person can stroll those same 2-1/2 miles along the Canal Side Rail Trail to the dam (basically the entire TF power canal) in less than 45 minutes.  So, what’s dragging these fish down?

Things are becoming clearer as information dribbles out from Conte Lab’s endless fish passage studies in the Turners Falls power canal via the FERC hydro-relicensing process on the Connecticut River.  What’s obvious is how little we know about conditions encountered by the thousands of migrating shad forced into the private canal.  Nor do we have any definitive science describing what happens to tens of thousands of shad that choose their ancient migratory route directly up the Connecticut to Turners Falls Dam.  These are fish seeking passage toward Gill, Millers Falls, and Northfield, MA; Brattleboro and Bellows Falls, VT; and Chesterfield and Walpole, NH.  That dam holds back migration-sustaining flow to feed FirstLight’s deregulated pumped-storage hydro plant inside Northfield Mountain.   

The first thing noticed from a FERC memo dated January 27, 2014, is that the 2008 – 2012 studies from the USGS fish lab are being provided “with the caveat that they contain preliminary data that is subject to revision and that the reports have not been subject to independent peer review.”  In short, this un-vetted research does not meet some basic scientific benchmarks for making long range decisions on river regulation.  And, while conducted by federal researchers, some of it is over a half decade old, while all of it’s been subsidized with power company funds.

Today just one-fish-in-ten passes upstream through that canal to the river beyond TF dam–no better than averages tallied there in the mid-1980s.  So why has hydro-company FirstLight had access to this study information over these years while the public has gone wanting?   And when do study findings from 2008, 2009 or 2010 get finalized—when do they get published and made available for peer review?  Is this public-science, or private consulting?  How much weight can FERC accord them?

Here are further tidbits from a January 30, 2014 memo released by FERC.  They’re from a follow-up phone call between FERC’s Ken Hogan and Conte Lab’s Dr. Ted Castro-Santos, a principal investigator in the Turners Falls canal studies.  “Specifically, Mr. Hogan sought information from Dr. Castro-Santos on the duration of the upstream migration of adult shad within the Turners Falls power canal.”  Though there isn’t an exact transcription for the public record, we do have this telling quote: “Dr. Castro-Santos stated that duration of the radio-tagged shad migration within the power canal from Cabot Station to the vicinity of the Gatehouse, is a median of 8-days.”

Examined carefully, the language of Dr. Castro-Santos’s reply is specifically—vague.  What it reveals is that most tagged spawning-run shad take over a week to swim less than 30 city blocks.  Some take much longer.  But on average that’s a full four days to swim the mile from The Farren Care Center to 18th Street, and another four days to fin the last 18 blocks to 1st Street–the “vicinity” of the dam.  Castro-Santos specifically describes fish as reaching “the vicinity of the Gatehouse.”   “Vicinity” in this instance, is exculpatory language.  It means shad experience further delay here, with some not proceeding upstream past TF dam.  It describes another fatal choke point in the power canal configuration–underscoring failed engineering, fish passage, and science. 

Curiously, Dr. Castro-Santos has noted at fisheries meetings that a small segment of the shad population that does manage to thread the canal maze and emerge above Turners Falls Dam to continue upstream arrives at the base of Vermont’s Vernon Dam just 1-1/2 to 2 days later.  That’s a 20 mile swim in 36-48 hours.  After 14 years of study and 34 years of excruciatingly poor fish passage through that canal towards the 50 miles of empty Connecticut River spawning habitat upstream, the only explanation for shad taking 8 days to arrive at the “vicinity” of the dam through a 2-1/2 mile-long canal is this: it’s a failure. 

 What’s dragged these fish down?—clearly an alien migration route, unasked questions and poor public science.  But electricity demand eases in spring; and FERC is asking good questions now.  Federal statutes require working fish passage and river flows that facilitate the time-sensitive spawning and migration requirements of the public’s fish.  Those requirements have clearly not been met at Turners Falls these last 34 years.  FERC releases its Study Plan Determination for new science required for hydro-relicensing on February 17th.

Unconscionable: The Fate of the “Canal Nine”

Note: the following piece appeared this August in Connecticut River Valley publications including: Vermont Digger, www.vtdigger.org; the Daily Hampshire Gazette, www.gazettenet.com, The Montague Reporter and The Shelburne Falls Independent, and at The Recorder www.recorder.com, (edited version).

THE FATE OF THE CANAL NINE

Copyright © 2013, by Karl Meyer     All Rights Reserved

Forty-three years after being chosen as the upstream route for migratory fish, the Turners Falls power canal remains the black hole of fisheries restoration on the Connecticut.  In current filings the US Fish & Wildlife Service is requesting telemetry coverage across the mid-Turners Falls canal to puzzle out the unexplained fate of thousands of fish.  Trout Unlimited wants balloon-tagged shad and more monitors bracketing its powerhouse to study turbine kills and migratory delay.  The Federal Energy Regulatory Commission wants a hydraulics study of that canal, where all migrants must bypass two turbine stations, then negotiate blistering turbulence just to have a shot at spawning in Vermont and New Hampshire.  On August 14, 2013, canal/dam owners GDF-Suez FirsLight rejected those studies as unnecessary in legal filings for a new 30 – 50 year federal operating license.

While every fish attempting to spawn upstream of Turners Falls dam must enter the canal, scores of questions about their fate there remain unanswered.  Basic questions like, do shad spawn in the canal, have never been studied–even though shad spend an average of 25 days there and just one-fish-in-ten that enters emerges beyond the canal.  US Geological Survey Conte Fish Lab researchers have been paid by Northeast Utilities and FirstLight for studies to improve the fish exit from the canal for the past 15 years.  Yet forty-three years after this system was put in place, it’s still one-fish-in-ten.  And canal spawning, germane to the ecosystem restoration puzzle, has never been studied.

Even more basic to success is this: if only one fish in ten makes it through—what’s the fate of the other “canal-nine”?  But you don’t pose that question if you want to keep being paid to study the public’s fish in the company’s private canal.  You study little sections of the canal–fiddle around near the company’s preferred exits and entrances—make big claims for tiny, discreet successes.  A mountain of data is collected, yet never finalized, published; nor peer reviewed.  After 15 years of study and reengineering, it’s still one-fish-in-ten.  Other agency experts wink in this shared belief: most fish entering that canal don’t survive.  Sliced-up in downstream turbines, they flush directly into the river.

“Unconscionable” is the term Dr. Boyd Kynard uses for plans afoot to move hundreds of thousands of shad into that canal via a new lift (as opposed to tens of thousands today.)   He’s an award-winning fish passage expert who logged over 25 years as a federal fish scientist– helping found the Conte Fish Lab while with the US F&WS.  Kynard believes the ineffective ladder system in place there for decades may have actually saved hundreds of thousands of fish from death in Cabot Station turbines, “The Cabot ladder is so bad most fish never reach the canal where most will exit downstream through deadly station turbines.”

Kynard, a fish behavior specialist who studied shad passage and turbine mortality at Holyoke Dam through the 1980s, believes a new lift below Cabot Station could prove the ecosystem’s next 50-year disaster.  He witnessed massive fish kills in Holyoke’s canals in the early 1980s when, starting in 1976, a new lift passed hundreds of thousands of fish upstream to spawn for the first time in 120 years.  It was hugely successful, but no one foresaw what would happen when adults headed back to sea.  While part of the migrants rode over the dam during high flows, others reencountered the dam-and-canal-system.  Tens of thousands got sucked into turbines at Hadley Falls Station or died in the canal–unable to return safely to the river. A stench of rotting fish hung over that city while dump truck after dump truck hauled tens of thousands of dead shad from the canal to the landfill.  (That condition was eventually remediated when dam owners installed a louver system in the canal to divert down-running shad into a pipe and back to the river, thus bypassing all turbines.)

But whereas Holyoke’s lift allowed shad to first spawn upstream in the river before encountering turbines, at Turners two hundred thousand fish could find themselves in a turbine-filled canal before ever getting a chance to spawn in Vermont, New Hampshire or northern Massachusetts.  And this canal’s Frances-type turbines are far more deadly than Holyoke’s.  Stressed, those newly-lifted shad can encounter two discreet turbine sites before meeting the massive canal turbulence near the dam.

This ecosystem can’t absorb another 40-year failure in the Turners Falls canal.  The USFWS, TU, and the Connecticut River Watershed Council are backing a study–adopted from Kynard’s Holyoke work, which would use low-frequency sound to deflect shad from entering the canal.  If deployed correctly it could send migrating fish straight upriver to a lift at the dam, like the one that’s succeeded at Holyoke for decades.  It’s a simple, inexpensive study–one FirstLight is already seeking to limit to a single year, or exclude altogether.  But it’s FERC who’ll decide by September 13th.  And they have a mandate to protect the public’s fish.

Stakeholder Comments, RE: FirstLight Hydro Generating Company’s Updated Proposed Study Plan (PSP) for Northfield Mountain Pumped Storage Project, FERC Project No. 2485-063; and Turners Falls Hydroelectric Project, FERC Project No. 1889-081

 

Dear Secretary Bose,

 

 

Please consider the following comments, changes and proposed improvements to FirstLight Hydro Generating Company’s Updated Proposed Study Plan (PSP) in order to achieve the best measurable outcomes for the public’s interest in a balanced and functioning Connecticut River ecosystem as you consider new operating licenses for hydropower generation at these two projects.

 

 

Comments refer to Updated PSP #s: 2.2.1; 2.3.1; 3.2.2; 3.3.1; 3.3.2; 3.3.3; 3.3.5; 3.3.6; 3.3.7; 3.3.8; and 3.3.19.

 

Comments:

 

 

2.2.1 & 2.3.1: Proposed Changes to Project Operation

 

FL Updated Proposed Study Plan, Numbers 2.2.1 and 2.3.1: Operator is considering additional generation by adding volume, flow and velocity in, 1(p.2-15): the Turners Falls Power Canal at either Station #1 or Cabot Station, or operating Cabot Station at full capacity; and, 2(p-2-35): at the Northfield Mountain Project.  Hydraulic capacity increase at TF/Cabot sites, and at Northfield Mountain would be near 2,000 CFS respectively.

 

Any back-dated decisions in adding generation at these two licensed sites may impact the effectiveness and criteria of studies that will be implemented in the interim, and may prove confounding to the two-year study regimen.  Both would certainly impact downstream habitats and flows.  What criteria is FirstLight looking at when deciding on new generation requests—and when will they reveal their choices?

 

3.2.2: Hydraulic Study of the Turners Falls Impoundment, Bypass Reach, (“power canal”—now omitted by FL) and below Cabot Station

 

 

Note: Hydraulic study of the TF Power Canal is a key need if this is again to be considered an upstream route for migratory American shad.  After 14 years of continuous study and project improvements near the head of the Turners Falls Canal, Gate House fish passage numbers are no more improved–nor consistent, compared to numbers of fish passing Holyoke Fish Lift, than they were a quarter century ago: Holyoke Lift versus the actual percent that were able to pass up through the TF Power Canal and through the Gatehouse: (Figures from the Connecticut River Atlantic Salmon Commission Tech. Committee Meeting, Secretary’s Report: 6/18/2013)

 

Gatehouse passage success: 1989: 2.7%; 1990:7.8%; 1991:10.5%; 1992: 8.3%; 1993:3.0%

 

Gatehouse passage success: 2009: 2.4%; 2010:10.0%; 2011:6.9%; 2012:5.4%; 2013: 9.2%.

 

 

 

(p. 3-50) “FERC has requested that FirstLight develop an unsteady state HEC-RAS model in the Turners Falls Impoundment, bypass reach, power canal, and below Cabot Station to the upper limit of the Holyoke Impoundment.”

 

 

FirstLight states that a hydraulic study of the TF power canal is unnecessary, as surface (WSEL) elevations fluctuate very little.  “Given the power canal’s limited WSEL fluctuations, FirstLight does not believe a hydraulic model of the power canal is warranted.”

 

 

FERC is correct.  A full hydraulics study of the TF Canal is needed.  It is necessary as baseline information if migratory fish continue to be diverted into the power canal.  It will also be critical information if generating capacity in the TF Canal and upstream at the Northfield Project is increased by 2,000 cfs, respectively(2.2.1 & 2.3.1).  This would certainly impact hydraulics at the head gates and downstream in the power canal.

 

There are 14 head gates at the TF Gatehouse flushing directly into the TF Power Canal.  Surface level elevations have very little to say about actual flow hydraulics at this site.  Those head gate openings and the fluctuating head-levels from the TF Impoundment behind the dam create a region of extreme turbulence in the canal running some 500 feet downstream from Gatehouse.  This is one of the bottlenecks in the power canal route that has not been overcome after 43 years of study and structural changes in this upstream route.

 

 

When the agencies and the public were taken on FERC site visits, only one group in three was given a tour of this side of the TF Gatehouse.  At that time, only 4 head gates were open.  The canal appeared a relatively calm place.  When all head gates are open—as the Northfield Project and Cabot are run in peaking modes, or the TF Canal is run at baseload capacity through the day, this region is a boiling-roll of water.  Surface speeds reach nearly 10 mph (as monitored by cyclists on the canal path).  We need to know how this affects velocity and turbulence throughout the water column

 

 

Given recent fish passage increases at Holyoke Dam, it is feasible that building a facility to lift migratory fish out of the CT River and into the TF Canal below Cabot Station could divert as many as 100,000 fish into the canal over a period of a few days.  Recent work by USGS Conte Anadromous Fish Research Center showed American shad spending an average of 25 days in the power canal.  Researchers did not investigate whether this was a signature of fish mortality, spawning, or milling. Nor has the TF canal ever been investigated as spawning habitat—which would have been logical, given those lengths of stopover.  American shad notably do not do well with stress.  Piling up the population in a power canal will likely result in major migratory delays and increased mortality—which needs a full investigation if this path remains an option.

 

This should be a two-year effort, to control for differences in flow years, fish tagging and handling, and to assure that full acoustic coverage is gained through proper array deployment.

 

American shad have not been able to negotiate this region of high turbulence since this canal route was chosen for them in 1980.  At Holyoke, as well as at Vernon Dam, fish follow attraction water that leads them directly upstream to the dams.  Rates of passage at both are within the acceptable range of 40-60% that the agencies have set as targets.  When the Connecticut River above Cabot Station—aka, the Bypass Reach, was allowed to be de-watered in deference to this power canal route, shad and herring were expected to locate and negotiate a series ladders, turns, turbines, and turbulence at a half dozen canal sites in order to reach upriver spawning areas.  It’s a migratory knot; created by humans.

 

The Connecticut River migratory fisheries restoration effort risks repeating four new decades of failure if it again ignores logic.  The TF Power Canal is in need of a full hydraulic study.

 

Hydraulic modeling must be done here in order to avoid another migratory fisheries restoration disaster at Turners Falls.  Northern Massachusetts, Vermont and New Hampshire have yet to see their guaranteed shares of the targeted shad and herring runs, nor has the program achieved anything near its stated goals:  “The intent of this program is to provide the public with high quality sport fishing opportunities in a highly urbanized area as well as to provide for the long term needs of the population for food,” as stated in the New England Cooperative Fisheries Statement of Intent in 1967.

FirstLight’s Water Level Recorders (River Stage)”The Water Level Recorders deployed by FL in 2010 that supplied “limited data” from the By Pass Reach and below Station 1 should be removed from “existing information” status.  WSEL monitoring in this reach needs to be redone.  Several more monitors at key sites are needed to protect resident and migratory fish, as well as the federally-endangered shortnose sturgeon, which gathers for pre-spawning in the pool immediately below the Rock Dam, and–when flows allow, chooses to spawn there.

 

 

Note *: personal communication from Dr. Boyd Kynard, fish behaviorist and CT River shortnose sturgeon expert:

 

“For 10 years between 1993 and 2007, adult sns were present at Rock Dam for 5 years prior to spawning occurring anywhere ( Rock Dam or Cabot Station). During the 5 years they were present, the mean number of adults present was 10.4 (range, 3-25). Thus, many adults moved to the Rock Dam spawning site before any spawning occurred at Cabot Station suggesting they preferred to spawn at Rock Dam.” (Refer to chapters 1 & 3, Life history and behaviour of Connecticut River shortnose and other sturgeons, 2012, Kynard et al, World Sturgeon Conservation Society publications, ISBN: 978-3-8448-2801-6.  Available through the North American Sturgeon and Paddlefish Society at: www.nasps-sturgeon.org/#!publications , or directly from Dr. Kynard at: kynard@eco.umass.edu

In the pool immediately below Rock Dam, 2. on the west side of the river, in the main stem channel, upstream of Rawson Island which is adjacent to, and just west of the Rock Dam.  That Rock Dam ledge continues through the island and reemerges as part of the thalweg near the river’s west bank.

 

3.3.1 Conduct Instream Flow Habitat Assessments in the Bypass Reach and below Cabot Station 

 

If migratory fish are again to be diverted into the TF Power Canal via a new lift in the river near Cabot outflows (proposed), special consideration needs to be made when considering siting the lift facility.

 

Federally-endangered shortnose sturgeon will likely enter the lift, and there exists the risk of putting them into the power canal where there is potential for turbine mortality.

 

Migratory delay: another reason for special care in considering diversion is migratory delay for American shad and blueback herring at this site.  If a lift gets built at Cabot, there will be a need for full-time monitoring personnel in order not to risk sending SNS into the canal.  Just as at Holyoke, with Atlantic salmon monitoring, the lift would then have to shut down—sometimes for weeks at a time, due to turbidity and the risk of NOT identifying a migrant salmon(or in this case, a federally endangered SNS).  This type of migratory delay would not likely be acceptable to the agencies, or FL (see FL’s added text about “without delay” under 3.3.19 : “Evaluate the Use of an Ultrasound Array to Facilitate Upstream Movement to Turners Falls Dam by Avoiding Cabot Station Tailrace.”

 

 

Existing Information and Need for Additional Information (18 CFR § 5.11(d)(3))

 

The IFIM Study needs to be conducted with increased WSEL monitors given FL’s stated intent to potentially increase generation and flow at the Northfield Project, Station 1, and Cabot Station.

 

Several more monitors at key sites are needed to protect resident and migratory fish, as well as the federally-endangered shortnose sturgeon, which gathers for pre-spawning in the pool immediately below the Rock Dam, and–when flows allow, chooses to spawn there.

 

Note *: personal communication from Dr. Boyd Kynard, fish behaviorist and CT River shortnose sturgeon expert:

 

“For 10 years between 1993 and 2007, adult sns were present at Rock Dam for 5 years prior to spawning occurring anywhere ( Rock Dam or Cabot Station). During the 5 years they were present, the mean number of adults present was 10.4 (range, 3-25). Thus, many adults moved to the Rock Dam spawning site before any spawning occurred at Cabot Station suggesting they preferred to spawn at Rock Dam.” (Refer to chapters 1 & 3, Life history and behaviour of Connecticut River shortnose and other sturgeons, 2012, Kynard et al, World Sturgeon Conservation Society publications, ISBN: 978-3-8448-2801-6.  Available through the North American Sturgeon and Paddlefish Society at: www.nasps-sturgeon.org/#!publications , or directly from Dr. Kynard at: kynard@eco.umass.edu

 

 

Need for Additional Information (3-53):  Where, exactly, did FL locate WSEL monitors in the By Pass Reach?  How do they intend to guard against “vandalism” ruining further data collections?

Additional WSEL monitors needed to capture fuller By Pass flows profile. In order to protect pre-spawning and spawning of shortnose sturgeon in this reach of river additional WSEL monitors should also be placed at: 1. In the pool immediately below Rock Dam, 2. on the west side of the river, in the main stem channel, upstream of Rawson Island which is adjacent to, and just west of the Rock Dam.  That Rock Dam ledge continues through the island and reemerges as part of the thalweg near the river’s west bank.

 

Table 3.3.1-1: Target Species and Life Stages Proposed for the IFIM Study Reaches.

 

Under Reach 1 & 2: blueback herring: add “spawning”—as New England Cooperative Fisheries Research Studies document BBH spawning in this reach, at the mouth of the Fall River.

 

 

Under Reach 1 & 2: shortnose sturgeon: add “pre-spawning.”

 

Note *: personal communication from Dr. Boyd Kynard, fish behaviorist and CT River shortnose sturgeon expert:

3.3.2 Evaluate Upstream and Downstream Passage of Adult American Shad

 

Study Goals and Objectives (18 CFR § 5.11(d)(1))

 

“The goal of this study is to identify the effects of the Turners Falls and Northfield Mountain Projects on adult shad migration. The study objectives are to:”

 

 

Add: “Determine route selection, behavior and migratory delays of upstream migrating American shad through the entire Turners Falls Power Canal.”

 

Add to “Describe the effectiveness of the gatehouse entrances;” …

 

 

ADD IN: “and describe the behavior of migratory American in the Turners Falls Power Canal within 500 feet of the gatehouse entrances.”

 

ADD IN: “Evaluate attraction for shad reaching the dam spillway under a range of spill conditions.” 

Note:  Since a lift is being considered at this site, evaluating spillway attraction is most important.

 

 

 “Evaluate attraction, entrance efficiency and internal efficiency of the spillway ladder for shad reaching the dam spillway, under a range of spill conditions;”  see immediately below.

 

Footnote 35 “This may be achieved with existing information; FirstLight is awaiting data from the USGS Conte Laboratory.”

 

 

NOTE: USGS has done 6 years (2008 – present) of study and data collection at Spillway and Gate House.  All of it remains “preliminary”—hence never finalized, or peer-reviewed.  Only “finalized” study data and findings should be included in FERC study plan design, and made available to all stakeholders for review.  All studies are partially FirstLight funded.

 

The Need for Additional Information

 

Under  Task 1: “Review existing information:”

Only finalized USGS study information should be considered.

Task 2: Develop Study Design:

As per FERC request, a radio and PIT tag study of the entire Turners Falls Power Canal should be included in this study.

 

 

Task 3: Evaluation of Route Selection and Delay

 

             Under: Radio Telemetry Tracking: Add in:

 

“Tagged fish will be tracked throughout the Turners Falls Power Canal during bothupstream and downstream migration with fixed antennae and mobile tracking; usingPIT tags in addition to radio telemetry tags.”

 

“Additional tagged individuals may need to be released farther upstream (Turners Falls power canal, * (ADD IN: “top of Cabot Station Ladder,”) upstream of Turners Falls Dam), to ensure that enough tagged individuals encounter project dams on both upstream and downstream migrations, that these individuals are exposed to a sufficient range of turbine and operational conditions to test for project effects, and to provide adequate samples sizes in order to address the objectives.”

 

Under: Video Monitoring

 

 

Video monitoring at the Spillway Ladder is insufficient.

 

Note: Video monitoring is insufficient in determining the number of fish attracted to the spillway.  It will only register fish that can FIND the Spillway Ladder Entrance.  This in confounded by a range of competing flows, water levels present in the By Pass, and spill from the dam.  A full range of telemetry tracking needs to be employed at the TF Spillway—not simply at the Spillway Ladder and SL Entrance.

 

Task 4: Evaluation of Mortality

 

Note: Preliminary USGS TF Canal studies have suggested uninvestigated data indicating mortality within the Turner Falls Power Canal.  Mortality tagged fish and data should be collected throughout the entire TF Power Canal, to correct for overall mortality.

 

 

The number of fish suggested to be fitted with mortality tags is insufficient in all these studies, and should be increased by a factor of two.

 

Table 3.3.2-1: Proposed locations and types of monitoring and telemetry equipment proposed for the upstream and downstream passage of adult shad study.

 

 

ADD in: (to identify migration routes and delays):

 

After “Cabot Ladder”, add new location: Eleventh Street Canal Bridge: PIT Tag Reader

 

Before “Rawson Island”, add new location: TF Power Canal, 400 feet downstream of Gate House.  PIT Tag Reader and Lotek SRX.

 

 

Also before “Rawson Island”, add new location: “Rock Dam Pool, immediately downstream of Rock Dam.”  Lotek SRX.

 

 

After “Turners Falls Spillway Ladder,” add: Turners Falls Spillway, Montague Dam.  Lotek SRX;  followed by a new location, add in: Turners Falls Spillway, Gill Dam.  Lotek SRX.

 

QUESTION: What is the exact location considered for “Below Turners Falls Dam” ?

 

 

3.3.3 Evaluate Downstream Passage of Juvenile American Shad

 

Task 3: Turbine Survival

 

Evaluations should be done for all turbines, with all turbines operating, at both Cabot and Station 1, to capture the broadest range of conditions at these sites.

 

 

3.3.5  Evaluate Downstream Passage of American Eel

 

Level of Effort and Cost (18 CFR § 5.11(d)(6))

 

Study ticket price is too expensive.

 

 

“The estimated cost for this study is approximately between $350,000 and $450,000.”

 

Note: Costs of this American Eel Study are prohibitive, particularly since there is no benchmark data on the ecosystem importance of eels above Mile 122, TF Dam.

 

This rivals the costs of all studies supported to assess migration and mortality of American shad, a restoration target species to Vermont and New Hampshire for 46 years.

 

 

 A significant proportion of that money could best be used to increase the scope of study: 3.3.2, and 3.3.7: Evaluate Upstream and Downstream Passage of Adult American Shad; and 3.3.7 Fish Entrainment and Turbine Passage Mortality Study.  These could then include a full study of the Turners Falls Power Canal–and increasing the number of mortality-tagged fish.

 

Cost effectively, a literature survey, and results from Holyoke Dam studies and Cabot data collection should suffice to gauge survival of American eel at Turners Falls/Cabot/Northfield.  A portion of the funding could be used to construct an eel-way at TF Dam—a relatively inexpensive structure.

 

3.3.6 Impact of Project Operations on Shad Spawning, Spawning Habitat and Egg Deposition in the Area of the Northfield Mountain and Turners Falls Projects

 

 

Under: Existing Information and Need for Additional Information (18 CFR § 5.11(d)(3))

 

Information as American spawning and spawning habitat is missing for the pool where shortnose sturgeon spawn, the Rock Dam Pool, immediately downstream of that notched ledge in the river.

 

Task 2: Examination of Known Spawning Areas Downstream of Turners Falls Dam

 

Note: The Turners Falls Power Canal needs to be investigated as a spawning location for American shad.  USGS studies have registered migratory shad remaining in the TF Canal for and average of 25 days.  Adult shad, which do not feed during spawning migration, must complete their salt-to-river-to salt spawning runs within 44 days in order to survive.  A critical need is to know whether these fish are spawning in the TF Power Canal, milling in the canal, or whether they have expired.

 

3.3.7 Fish Entrainment and Turbine Passage Mortality Study

 

Increase the number of mortality-tagged fish; run tests for all turbines at Station 1 and Cabot, with all turbines operating.

 

3.3.8 Computational Fluid Dynamics Modeling in the Vicinity of the Fishway Entrances and Powerhouse Forebays

 

Existing Information and Need for Additional Information (18 CFR § 5.11(d)(3))

 

 

Note: Three-dimensional CFD Modeling needs to extend 500 feet downstream of the Gate House in the Turner Falls Power Canal to capture the influence of the 14 head gates at the dam on migratory fish behavior and delay.

 

3.3.19 Evaluate the Use of an Ultrasound Array to Facilitate Upstream Movement to Turners Falls Dam by Avoiding Cabot Station Tailrace  

 

 

General Description of Proposed Study

 

FirstLight’s added language: “This study will be conducted in 2015 pending the results of Study No 3.3.1 and Study No. 3.3.2, which include analysis of historic fish passage data.”

 

Note: This study should be conducted for two seasons, the same time span accorded to American eel. 

 

Historic fish passage data likely has only minimal importance, as early spring freshet flows over the TF Spillway generally out-compete Cabot Station flows and send fish treading water at the base of TF dam—often for weeks.  Those freshet flows at the dam typically overwhelm any flow from the Spillway Ladder, and the shad essentially run down their engines treading water until the freshet subsides.  At that point, flows over the Spillway are allowed to be cut to 400 cfs, which sends the shad downstream to fight their way into the spill of the canal system. For this reason, historic data has limited value as the quantified presence of shad at the base of TF Dam is missing, and data on the effectiveness of Spillway attraction flow does not exist.

 

Resource Management Goals of Agencies/Tribes with Jurisdiction over Resource (18 CFR § 5.11(d)(2)) 

 

“• American shad must be able to locate and enter the passage facility with little effort and without stress.”

 

“• Where appropriate, improve upstream fish passage effectiveness through operational or structural modifications at impediments to migration.”

 

 

“• Fish that have ascended the passage facility should be guided/routed to an appropriate area so that they can continue upstream migration, and avoid being swept back downstream below the obstruction.”

 

Note: This study should not be contingent on results of other studies, and should be conducted for two seasons. 

1.    Its effectiveness at another Connecticut River bottleneck has been tested.

 

2.    It addresses the need to avoid migratory delay and failure for two key species that have topped the CT River fisheries restoration since 1967: American shad and blueback herring.

 

3.    It keeps the fish migrating in the Connecticut River.

 

4.    If it proves effective, it would simplify fish passage mechanisms and cut by millions of dollars the cost required for passing TF Dam.  A single set of lifts at the dam would pass fish, as it has at Holyoke for decades.

 

5.    It would avoid the expense and pitfalls of requiring fish to negotiate two mechanisms at Cabot Station, another out of the canal, and a final grid through Gate House. 

 

6.    It presents the opportunity to avoid the stress required of migratory fish when they are driven into the TF Power Canal, then must find their way through turbulence and fight a path through several more untried, built mechanisms.

 

7.    USGS studies have found the average passage time through the TF Canal is 25 days; whereas transit times in the actual river—from Holyoke to TF Dam, or from TF Dam to Vernon Dam, are generally accomplished in a matter of 2 – 3 days.

 

8.    This would avoid the problem of shortnose sturgeon being picked up in a lift at Cabot Station, which would be a cause for further migratory delay as lifts would have to stop to retrieve fish—and also might have to be shut for days during times of high turbidity. 

Existing Information and Need for Additional Information (18 CFR § 5.11(d)(3)) 

Information from Proposed Project Changes, Flow, Hydraulics, Habitat, and Telemetry studies: 2.2.1; 2.3.1; 3.2.2; 3.3.1; 3.3.2; should be used to inform the implementation of this study. 

 

FirstLight’s added-in text:

 

“however, simply repelling shad from the Cabot tailrace is not a satisfactory result, for this behavioral barrier to be successful the fish would also have to keep going upstream, without delay, as opposed to dropping down below Cabot.”

 

Note: this caveat does not present a satisfactory argument.  In order to be proven ineffective, delays caused by sonics repelling fish from the Cabot entrance would have to out-compete any delays American shad and blueback herring encounter by being drawn to the Spillway during spring freshet and not find a readable upstream flow or passage at the dam. To this must be added the delay and stress of having river attraction and Spillway flow cut to 400 cfs, thus sending them DOWNSTREAM to fight their way into the TF Power Canal. 

Question: Should FL be deciding what constitutes delay?  Shouldn’t American shad dropping back two miles downstream from the TF Spillway to Cabot Station be considered an “unsatisfactory result”? 

 

Methodology (18 CFR § 5.11(b)(1), (d)(5)-(6))

 

Note: Ensonification coverage may need to be deployed far enough out into the main stem so as to lead fish out to the thalweg/main flows on the west side of Rawson Island.  Simply steering fish out of the Cabot entrance, but then only allowing them the choice of the minimal flows coming down through Rock Dam at the time paltry 400 cfs release would likely keep the fish milling and confused below Station # 1. 

Study Schedule (18 CFR § 5.11(b)(2) and (c))

 

FirstLight’s Added text: “ 

“If performed, the study is anticipated to conclude by mid-July 2015.”

 

Note: This should not be a contingent study.

THE RIVER FIX FOR FATAL ATTRACTION

The River Fix for Fatal Attraction

With a salmon hatchery program no longer clouding issues, the US Fish & Wildlife Service, National Marine Fisheries Service, and directors from MA, VT, NH and CT have a singular opportunity to redeem the Connecticut River restoration. They’re currently making choices for restoring migratory fish north to Bellows Falls, VT, begun under the 45 year-old New England Cooperative Fisheries Compact. The decisions stem from the 1965 Anadromous Fish Conservation Act. They’ll seal this ecosystem’s fate at four federally-licensed dams and the Northfield Mountain Pumped Storage Station until 2058.

US F&WS’s Region 5 Director Wendi Weber, John Warner, and Ken Sprankle will join National Marine Fisheries’ Daniel Morris, Julie Crocker, and MA Fish & Wildlife’s Caleb Slater in making the decisions—with input from state directors. Their 1967 mandate is restoration of shad and herring runs to offer the public “high quality sport fishing opportunities” and provide “for the long-term needs of the population for seafood.”

Sadly, in 1980 their predecessors abandoned two miles of the Connecticut to the power company operating at Turners Falls and Northfield Mountain. By allowing privatization of the river at mile 120, they killed chances of passage success for millions of American shad barred from spawning at Greenfield, Gill and Northfield, MA, right to the foot of Bellows Falls at Walpole, NH at mile 172. Unwittingly, they also continued the decimation of the ancient spawning grounds of the river’s last, 300, viable federally-endangered shortnose sturgeon.

Instead of mandating river flows and a direct route upstream to a lift at the dam, they acquiesced to diverting migrants into a power canal. That Rube Goldberg–a three-trick knot of currents and ladders, proved an utter failure to the hundreds of thousands of shad moving upstream annually through elevators at Holyoke Dam. There, via a lift built in 1955, 380,000 American shad streamed north in 1980. It’s the East Coast’s most successful fish passage; it by-passes the city’s canals.

Half or more of those shad swam upstream; but foundered in the treacherous Turners Falls complex. At the dam, just as today, some depleted their energies by treading water for weeks—washed back and forth by a power company’s deluge-and-trickle releases, finding no elevator or upstream entrance. Many eventually turned back, only to be tempted by spill from their power canal. Fish unlucky enough to ascend the ladder there found a desperate compromise. Over 90% wouldn’t exit alive. Just as today, alien habitat and extreme turbulence overwhelmed them. Only 1-in-100 emerged upstream. For the rest, a turnaround spelled almost certain death in turbines. Others lingered for weeks in an alien canal environment, until they expired. Just as today.

This year over 490,000 shad passed Holyoke. Half or more attempted to pass Turners Falls. Just 26,000, or 1-in-10, swam beyond the dam–a percentage consistently reached in the 1980s. This is described as “success” by US Geological Survey Conte Lab scientists, Dr. Alex Haro and Dr. Ted Castro-Santos, after fourteen seasons of canal study. In work garnering annual power company subsidies, they’ve attempted to model that canal is a viable migration path.

I interviewed Dr. Haro in 2007, subsequent to a 1999-2005 study finding shad passage at Turners Falls had plummeted to “one percent or less” directly on the heals of Massachusetts 1999 energy deregulation for the Northfield Mountain-Turners Falls’ complex. I asked why passage had failed there, “I wouldn’t call it failure,” Haro replied. Fish passage saw no significant rebound until 2010, when the effects of GDF-Suez’s Northfield Mountain plant were stopped cold for 6 months—sanctioned by the EPA for massive silt dumping. Likewise, Dr. Castro-Santos’s claims to passage of one-in-ten fish as progress seem deeply troubling when his findings, after 14 years, are just now revealing shad dying “in droves” in that canal, “We don’t know why.”

In 1865, James Hooper, aged 86, of Walpole, NH reported: (from The Historical Society of Cheshire County (NH) “The area just below Bellows Falls was a famous place for catching shad because they gathered there but did not go up over the falls. The fish were caught with scoop nets. One spring Hooper helped to haul out 1300 shad and 20 salmon with one pull of the net.”

Citizens upstream of the 1798 Turners Falls Dam need not accept the dead shad runs and severed ocean-ecosystem of the last 214 years at a dam operated to cull price-spikes from the electricity “spot market.” An 1872 US Supreme Court decision against owners of Holyoke Dam mandates passage of the public’s fish. Nor do citizens from Old Saybrook, CT to Bellows Falls have to accept endangered sturgeon, a lethal canal, and a dead river at mile 120. After 32 years of fatal attraction at Turners Falls, its time to stop steering fish into a canal death trap. Holyoke proves that’s possible.

The Last, BEST Hope for the CT River: GET INVOLVED!

The Federal Energy Regulatory Commission re-licensing process for GFD_Suez FirstLight Power’s Northfield Mountain and Turners Falls Power Canal Projects on the CT River officially began with FirstLight’s Notice of Intent to file for two new operating licenses to use our river to make electricity for the next four decades.  Over the next four months–until the end of February 2013, officials from the US Fish & Wildlife Service, National Marine Fisheries Service, and directors of fish & wildlife programs will be meeting to decide the critical studies needed to restore and safeguard the Connecticut River through the year 2058.

FirstLight is anxious to see that the main studies guiding the “restoration” of migratory fish is based on moving migratory fish upstream through their power canal, NOT upstream through the ACTUAL Connecticut River, sitting directly adjacent to their canal.  The Power Canal route has proven a disaster, patently deadly for any river restoration.  After 32 years, and study after study, “improvements” enable ONE fish in TEN, to emerge alive, upstream of the Turners Falls Power Canal passage.  It is a death sentence for any true restoration of the river.

To learn more, tune into a broadcast of Greenfield Community Television’s LOCAL BIAS, with host Drew Hutchinson.  In the program I attempt to explain how complexity is clouding the thinking and priorities of our wildlife officials, and h0w simply requiring the Connecticut River to be allowed to flow through its own bed at critical times is the key to having a working ecosystem for the next three generations to come.

Here’s how you can tune in:

Episode (# 127) will be cablecast Wednesday 5:30pm, and Thursday and Saturday 9pm starting November 7th for two weeks. It will also be available via video on demand at gctv.org sometime next week.
