Winter Tempc;rature Operation of Libby Dam for Kootenai River burbot

1. SOR request
Specifications:
U.S. Fish and Wildlife Service staff and others, as members of the Kootenai Valley Resource Initiative (KVRl) burbot sub-committee, request that the Corps of Engineers use the selective withdrawal system at Libby Dam to release the coolest water possible in November and December, 2006 before temperature stratification limits the temperature control capability. The purpose of this operation is to provide cooler river temperatures downstream of Bonners Ferry, and also to determine how radio-tagged burbot in the Kootenai River respond to these temperatures. This will likely result in November and December temperatures slightly cooler than the existing selective withdrawal temperature rule curve (Figure I). This deviation from the temperature rule curve has been coordinated with Montana Firth, WildIife & Parks (MFWP). MFWP asked that the selective withdrawal gates be removed incrementally to assure that daily temperature change remains within 2 degrees F per day; gates should be removed systematically during the last 2 weeks of October (17th through 31st) to slowly lower river temperature to the minimum by November 1 (on average, a span of about 5 degrees C, or 9 degrees F; Figure 1).

2. Participants Susan Martin, Supervisor, Upper Columbia Fish and Wildlife Office. U.S. Fish and Wildlife service, on behalf of the Kootenai Valley Resource Initiative-Burbot Recovery sub-committee. U.S. Fish and Wildlife, Idaho Department of Fish and Game, Pend Oreille/Priest Lakes Commission

Lower Monumental Spillway Operations for April through August 2006

1. SOR request Navigation Objectives
The objective of this SOR is to provide safe navigation below Lower Monumental Dam for arriving upbound and departing downbound vessel traffic during the period of time when spill patterns are adjusted for the juvenile salmonid outmigration.

Specifications
This SOR recommends that the special operation of the Lower Monumental spillways, to accommodate outmigrating salmonids, be modified to allow for cessation of spill, if needed, for the period of time it takes a vessel to enter or depart the lock. This is estimated to be approximately twenty minutes

Dworshak Flow

1. SOR request
Specifications:
Maintain current outflow of 12 Kcfs from Dworshak Dam. Reevaluate Dworshak outflow on Monday morning, July 31, 2006.


2. Participants U.S. Fish & Wildlife Service, Idaho Department of Fish and Game, Oregon Department of Fish and Wildlife, the Washington Department of Fish and Wildlife, NOAA Fisheries, Nez Perce Tribe, Shoshone-Bannock Tribes, and the Columbia River Inter-Tribal Fish Commission.
3. TMT recommendation Operate Dworshak at 12 kcfs for July 29-31 and discuss operation July 31 TMT meeting.
4. AA decision The COE implemented the SOR
5. IT recommendation  
6. AA decision (after IT)
  
7. Actual Operation

July 31. TMT held a conference call to discuss current conditions, review COE modeling and discuss Dworshak operations. The COE operated Dworshak over the weekend at 12 kcfs. During an FPAC conference all prior to the TMT call on July 31, the salmon managers developed a short-term recommendation to operate Dworshak at full powerhouse as soon as reasonably possible, and target 43F water out of the project if possible. The COE implemented the request to operate the project at full powerhouse and continued until a different operation was recommended.

August 9. TMT reviewed current conditions and looked at two modeling scenarios submitted by the COE- ERDC Mike Schneider depicting potential outcomes for operating the project: 1) at full powerhouse until August 15 and reducing to 7.5 kcfs through the end of August, or 2) going to 7.5 kcfs today (8/9) and maintaining for 15 days, then increasing flows to 10 kcfs for the remainder of August. Hells Canyon flow projections were the primary unknown factor and it was noted that the assumption made in the scenarios underestimated the actual flow that came down over the past week. Weather was forecasted to remain moderate over the next few days with no extreme weather patterns predicted for the next two weeks. During an FPAC meeting, a consensus was reached to recommend maintaining full powerhouse out of Dworshak until there is a need to drop to 7.5 kcfs in order to meet a 1535. elevation target by the end of August, with the caveat that if extreme weather hits, the issue would be revisited. Idaho added that there was also value in adjusting flows out of Dworshak per the flows coming down from Hells Canyon. The COE implemented the operation to maintain full powerhouse at Dworshak until August 16 unless the salmon managers provided an alternative recommendation between 9-16 August.

August 16. COE reported that the latest STP model showed volumes of 191 kaf for July to the end of August, and that operating at full load for the remaining 16 days in August would result in minus 82 kaf for flow augmentation at the end of August. The Dworshak elevation was 1551'. Russ Keifer, ID, reported that at the earlier FPAC meeting, Greg Haller, Nez Perce Tribe, recommended staying at full power house until the evening of August 22 then dropping to 7.7 kcfs for the remainder of August. Keifer stated that this recommendation was unanimously supported by all FPAC members present. The COE was asked to do a model run for this option, to forecast when elevation would hit 1535'. The estimated date was August 28th. Greg Haller presented this information to the Dworshak Operations Board which developed a draft plan for the 200 kaf reserved per the Dworshak agreement. Dave Statler, Nez Perce Tribe, reiterated that with the uncertainty of temperatures, operations should hold, and that the specifics on how to manage the 200 kaf would be worked out by the Dworshak Operations Board. The COE implemented the TMT recommended Dworshak operation and would revisit this operation on August 30.

August 30. COE reported that the Dworshak forebay was at elevation 1532.3-.5', expecting to reach 1531' by midnight on 8/31. Temperatures at Lower Granite were holding steady between 66-67 degrees, the Little Goose tailwater temperature was just below 68 degrees, and Lower Monumental had recently dropped below 68 degrees as well. Outflows at Dworshak were at 7.6 kcfs, with temperatures between 46.5 and 47.5 degrees. Anatone outflows were between 14-23 kcfs, with temperatures in the low 70.s. Orofino outflows were 1.2 kcfs, with temperatures also in the low 70.s. Jim shared a graph projecting thermocline temperatures at Dworshak at elevation 1520'. Using this graph, Jim predicted outflow temperatures of 48 degrees when the project reduces to minimum outflows when the pool elevation reaches 1520 feet. Operations are expected to continue with outflows at 7.6 until September 6, and then begin ramping down to 5. 4 kcfs until the Dworshak elevation reaches 1521'. Flow will then be reduced to 2.4 kcfs for 1 or 2 days, then to minimum outflows to reach elevation 1520'. COE graphs on the TMT website predicted elevations will reach 1520' by September 15 or 16. It was noted that the expected volume for flow augmentation in September, per the Dworshak Board agreement, was around 160 kaf.

September 13. COE reported that Dworshak elevation was at 1520.5' as of the evening of September 12. As per the Dworshak Operations Board's plan for September, ramp rates held at 7.4 kcfs (one big unit / one small), and then dropped to 4.5 kcfs on 9/6. As of 9/13, flows were down to 2.4 kcfs. At 2200 hrs on 9/13, the COE dropped to minimum flows (1.3-1.6 kcfs) and will hold until Dworshak reaches 1520'.

Libby & Hungry Horse Operations for June through September

1. SOR request Biological Objectives
The objective of this SOR is to implement the Northwest Power and Conservation Council.s Mainstem Recommendations for operation of Libby and Hungry Horse dams from July through September. The proposed operation will provide habitat for ESA listed bull trout and provide improved environmental conditions for other resident fish that inhabit the reservoirs and the rivers above and below Libby and Horse dams. The Council.s recommended operations at Libby and Hungry Horse dams will provide environmental benefits to resident fish in Montana without harming ESA listed Snake River fall chinook as they migrate through the Lower Columbia Reservoirs.

This SOR proposes to implement an evaluation of the physical and biological effects of the proposed operational changes for Libby and Hungry Horse. Fisheries scientists in the lower Columbia River determined that existing research could not isolate changes in fish survival attributable to this operation strategy. Physical changes in flows and water quality (primarily temperatures) that occur in reservoirs and rivers in Montana and the Lower Columbia River below McNary will be evaluated. Experiments have been designed and are being implemented in Montana to evaluate the biological changes that result from implementation of this SOR.

Specifications
Implement the Northwest Power Planning Council.s Mainstem Recommendations for operation of Libby and Hungry Horse dams during June through September. The Council.s recommended operations will require the following detailed specific operations at each project.
2. Participants Montana Fish Wildlife & Parks & Kootenai Tribe of Idaho
3. TMT recommendation Many of the salmon managers felt that given the court ordered spill, a policy decision was needed on this issue and recommended that IT discuss and decide.
4. AA decision Defer to NOAA
5. IT recommendation IT representatives requested that TMT continue discussing alternative or modified operation proposals that would, from a technical perspective, meet or get close to the various regional interests.

IT supported the TMT subgroup recommended operation and was subsequently sent to various federal legal counsel for review and submission to the court process.

6. AA decision (after IT)
 NOAA brought forth a proposed operation based on current forecasts and a desire to try to meet the interests of the full region. A subgroup of representatives from Montana, Oregon, CRITRC, NOAA, BPA and COE met to review the current information and developed a proposal that included NOAA.s suggested operation and likely impacts on flow at McNary. The TMT subgroup sent a memo for discussion during an IT call which recommended maintaining 15 kcfs flows at Libby through August 31. Similarly, a flat flow of 3 kcfs was recommended for Hungry Horse which was believed would draft the project 10' by August 31.
7. Actual Operation COE reported that as of the evening of July 25th, per recommendation, operations flows at Libby were reduced to 14-14.5 kcfs. BOR reported that Hungry Horse was ramping down 3 kcfs and was expected to hold until the end of August. COE planned to begin ramping down Libby flows from 14 kcfs on 8/31 at 10 p.m using the BiOp ramp rates. Ramp down will continue until a flow rate of 9 kcfs is reached. More details on the specific operation will be coordinated between COE, MT and BPA, and TMT will check in on Libby operations at the September 13 TMT meeting. Hungry Horse will begin ramping down starting Friday, to meet the Columbia Falls minimum. COE reported that Libby elevation was at 2440.6', with outflows at 9 kcfs on 9/13. ESP inflow analyses depicting Libby releases continuing at 9 kcfs through September showed a very small expected elevation range, of 2437.8' - 2437'. BPA noted that Bonneville will likely request ramping down to 6 kcfs at the end of September. As ramp rates between 9-6 kcfs for September are 1 kcfs per day, the ramp down will likely begin on the evening of September 27th. The action agencies noted the continued need for flexibility with respect to power needs, and agreed to check status at each TMT meeting. COE ramped down to 4.4 kcfs by 1 October and plans to hold at this flow until into November-December.

2006 Dworshak Summer Operations

1. SOR request General Framework
Operate Dworshak during summer for temperature control and flow augmentation, shaping augmented flows to achieve the target temperature standard of 68F as measured at the Lower Granite tailrace. Limit cold water releases during the first half of July for rearing fall Chinook juveniles in the lower Clearwater River. After July 15, maintain continuous, evenly distributed discharges of 10 kcfs (full powerhouse capacity) to cool the Lower Snake. Provide discharges in excess of 10 kcfs, up to a maximum of 14 kcfs, as necessary to meet the target Lower Granite temperature standard, pursuant to actual inseason conditions. Achieve a target elevation of 1535 msl or higher by August 31 tO preserve 200,000 acre-feet for September temperature/flow augmentation control as per the SRBA agreement. The management of 200,000 acre-feet (elevation 1535 to 1520 msl) will be determined by the Dworshak Board.1 Achieve a target elevation of 1520 msl during September.
2. Participants Nez Perce Tribe
3. TMT recommendation Nez Perce representatives provided an overview of the Nez Perce proposal for Dworshak operations through the summer. After much discussion, TMT did not support the recommendation as a proscriptive tool, but acknowledged that there was support for the general concepts in the framework of the proposal. The Nez Perce representatives clarified that their intention with the recommendation was similar to the group.s interest, and will now need to decide if/how to re-write the recommendation.
4. AA decision COE proposed going to 43F temperature releases from Dworshak, and increasing outflows to 7.2 kcfs as soon as possible. And, when Lower Granite temperatures reach a rolling 24-hour average of 67F, this will trigger the COE to increase Dworshak outflows to full powerhouse. Montana did not support the stepped approach and requested that Dworshak go to full powerhouse immediately. TMT could not decide how much water and what trigger to use for release for resident and anadromous fish and decided that it should be a policy level decision.
5. IT recommendation IT agreed to follow an operation that would use a rolling 24-hour average temperature of 67F at the Lower Granite tailrace gage to trigger an increase in Dworshak release to maximum powerhouse capacity (9.5 kcfs) at 43F and continue monitoring the temperatures in the Clearwater and Lower Snake Rivers. The temperature trigger was met that a.m. and releases increased to 9.5 kcfs with the big unit in undershot mode and both small units in overshot mode.
6. AA decision (after IT)
 Follow IT recommendation.
7. Actual Operation

June 30 - July 4: TMT agreed to cut flows back to 4.2 kcfs at 43F (using both small units, one overshot/one undershot mode) and monitor the temperature gages at Anitone for trigger to increase flows. If the rolling 24-hr average flow reaches 70F at Anitone, then increase flows to 7.4 kcfs at 43F, if the rolling 24-hr average flow reaches 71F at Anitone, then increase flows to full powerhouse at 43F.

July 4: The temperature trigger of the rolling 24-hr average flow of 70F at Anitone was reached so Dworshak increased releases to 7.4 kcfs with the big unit in undershot mode and one little unit in overshot mode.

July 5: Met temperature trigger of rolling 24-hr average flow at 71F at Anitone and increased releases from Dworshak to full powerhouse of 9.5 kcfs. TMT agreed to try to get coldest water possible released for a few days and revisit on July 7. USFWS was going to discuss impacts of these colder temperatures with Dworshak Hatchery Manager and report back with impacts and temperature thresholds. This operation released all water from units in undershot mode. Other options discussed would be to use the Regulating Outlets (2 kcfs / RO) to access cooler water. The RO intakes are located at the lowest elevation (1350 ft) in the forebay (coldest water). Jim Adams was going to update the thermocline of the reservoir and look at water temperatures and elevations for July 7 TMT discussions.

July 7-19: Based on the latest thermocline for Dworshak forebay and the discussion for the release of more cooler water during the TMT conference call, the Dworshak outflow was increased to 11.5 kcfs with 2 kcfs from one RO and full powerhouse (9.5 kcfs) with the big unit and one small unit in undershot mode and the other small unit in overshot mode. Maintain target temperatures of 43F and keep TDG levels below 109%. The results of this operation and possible changes will be discussed Monday, July 10.

July 19: TMT agreed to increase flow through the RO up to 4.4 kcfs or the gas cap of 109% with full powerhouse (9.6 kcfs), one small unit in overshot mode, big and small unit in undershot mode. The hatchery will monitor water temperatures and may request a change in temperatures if possible by moving the small unit in overshot mode to warmer water. This operation will continue through the weekend and revisit this operation on July 24 TMT call. Total discharge is 14.1 kcfs.

July 24. COE reported that Dworshak had been operating at 13.6 kcfs outflows (full powerhouse plus 3.9 kcfs through the RO's). Lower Granite tailwater temperatures have remained just below 68F. Orofino temperatures were around 80F with a flow rate of 2.4 kcfs; Anatone temperatures were around 76F, and flows were around 22-28 kcfs. The COE suggested that Dworshak could operate all units in undershot mode and effectively reduce temperatures by about 1F, to around 42-42.5F. NOAA recommended, given the updated flow augmentation forecast, reducing project discharge to 12 kcfs with all units in undershot mode and revisiting the operation during the TMT meeting on Wednesday, July 26.

July 26. COE reported that Dworshak discharges on July 25th were reduced to 12 kcfs, with all three units in undershot mode, per the TMT conference call. STP volume graphs showed that holding Dworshak at 10k result in a negative for augmentation flow at the end of August. Two proposals were expressed: 1) operate to 10 kcfs as soon as possible or 2) maintain 12 kcfs over the next four days and check back in via a TMT conference call on Monday, July 31st. A salmon manager Caucus was held, during which a suggestion was made to maintain 12 kcfs until midnight on Friday, then go to 11 kcfs over the weekend and have a FPAC/TMT check in on Monday, July 31, at 11 a.m.

July 28. Salmon Managers submitted SOR 2006-6 to operated Dworshak over the weekend at 12 kcfs and discuss at 31 July FPAC meeting for future recommendations..

Lower Granite Spillway Operations for April through August

1. SOR request Navigation Objectives
The objective of this SOR is to provide spill relief at Lower Granite Dam for departing down bound vessel traffic during the period of time when pool levels are required to kept at MOP, for the juvenile salmonid outmigration, and stream flows exceed 75KCFS.

Specifications
This SOR recommends that the special operation of the Lower Granite spillways, to accommodate outmigrating salmonids, be modified to allow for a more navigation friendly spill pattern and the reduction or cessation of spill, for the period of time it takes a vessel to depart the lock and clear the obstructing point of land, on the north shore, approximately one half mile below the dam. This is estimated to be approximately twenty minutes.

2. Participants Columbia River Towboat Association
3. TMT recommendation Request was supported. No TMT objections were raised to the spill reduction at Lower Granite during lockages, to RSW plus training spill, for a total of 18-20 Kcfs spill.
4. AA decision  
5. IT recommendation
6. AA decision (after IT)
  
7. Actual Operation A teletype was issued April 19th which allowed spill adjustments for safe navigation.

Snake River Transportation of Juvenile Salmonids

1. SOR request According to the Court Order transportation is to begin at the Snake River transportation sites on April 20, 2006. Delay initiation of transportation of juvenile salmonids until April 24 at Little Goose Dam and April 28 at Lower Monumental Dam.
2. Participants U.S. Fish & Wildlife Service, Idaho Department of Fish and Game, Oregon Department of Fish and Wildlife, the Washington Department of Fish and Wildlife, NOAA Fisheries, Nez Perce Tribe, Shoshone-Bannock Tribes, and the Columbia River Inter-Tribal Fish Commission.
3. TMT recommendation A technical consensus was reached at TMT that supported moving forward with the request. Parties in support included NOAA, Oregon, Idaho, Washington, Montana, BPA, BOR, Paul Wagner provided a memorandum to the Corps about the Biological rationale for implementing a staggered start of transportation from the Lower Snake River projects. This morning (April 20th) Corp attorneys coordinated with the Department of Justice who sent Judge Redden a letter notifying the court of TMT consensus of this operation. Attached to the letter was Paul's memorandum. Accordingly, the Corps is implementing the staggered transport operation.

The Dalles Dam Spillway Limitations

1. SOR request In the event that daily flows exceed 360 Kcfs at The Dalles Dam in the next several weeks, add hours to the John Day Dam daily spill period to maintain mainstem juvenile passage survival through the Lower Columbia River. (This specification assumes Spillway 7 is back in operation on April 10, 2006. However, if Spillway 7 is not available, the specification should be implemented when flow exceeds 315 Kcfs.)
Additional hours can be added to spill at John Day Dam to increase survival at this project. This alternative will not exceed the total dissolved gas level at this project. The daily volume of spill foregone at The Dalles Dam should be determined on a real time basis when spill percentages fall below 40%. This volume should be added to spill at John Day Dam in hourly increments when the computed volume allows an hourly increment at John Day Dam to meet 25% of instantaneous flow. The 25% of hourly instantaneous flow is the minimum needed to achieve adequate egress conditions below this project. The first hourly increment should be added prior to the nighttime spill period. If additional hours exist they should also be added prior to the daily spill period.
2. Participants U.S. Fish & Wildlife Service, Idaho Department of Fish and Game, Oregon Department of Fish and Wildlife, the Washington Department of Fish and Wildlife, Nez Perce Tribe, Shoshone-Bannock Tribes, and the Columbia River Inter-Tribal Fish Commission.
3. TMT recommendation
4. AA decision The COE responded that their policy position is to not provide make up spill in this or other similar situations. The action agencies asked the salmon managers what their preferred operation would be if it is not possible to spill 40 percent of total river flow through bays 1-6 at The Dalles during wire rope replacement. The salmon managers replied that they would prefer spilling less than 40 percent of total river flow through bays 1-6 rather than using additional bays to achieve 40 percent of total river flow.
5. IT recommendation

Spill at Bonneville Dam for the March Spring Creek Hatchery Release

1. SOR request

The Salmon Managers listed above are requesting the following fishery operations at the Bonneville Project following the March 2 Spring Creek Hatchery tule fall Chinook release:
  1. No operation of unscreened units at Bonneville Powerhouse II and follow the turbine operating priority in the Fish Passage Plan;
  2. Operate Powerhouse II as first priority. Fully load PH II before operating PH I;
  3. Operate turbine units within 1% of peak efficiency;
  4. Operate juvenile and adult facilities according to criteria;
  5. Beginning March 3, operate the Bonneville Project to maintain a minimum 14.5 foot tailwater elevation. This elevation is sufficient to allow 50,000 cfs of spill while maintaining a maximum level of 105% TDG (factored for depth compensation) the expected highest elevation (11.5 foot tailwater) chum salmon redds at the Ives Island complex and on the Oregon shore below Multnomah Falls.
  6. Beginning March 3, monitor sub-samples at the Hamilton Island Juvenile Monitoring Facility (JMF) facility. When sub-sampling at the JMF indicates large numbers of sub-yearling Chinook have reached Bonneville Dam, contact COE Reservoir Control Center to begin spill and B2CC operation;
  7. Operate for five days at 50,000 cfs spill and B2CC operation, or to an estimated 95% fish passage index (defined as the estimated percent of fish from the release group that have passed the project), which ever comes first. Adjust the spillgates to the best bulk pattern available. If the B2 corner collector is not operational on March 2nd, operate by spilling at Bonneville for five days, starting at 50,000 cfs spill level and if the TDG levels are low ramp up the spill in 5,000 cfs increments toward the goal of 75,000 cfs for this period.
  8. At no time is spill to exceed 120% total dissolved gas measured at the downstream Warrendale gauge, or 115% at the Camas/Washougal gauge, as allowed under the dissolved gas waivers from the states of Oregon and Washington;
  9. We request that the Action Agencies use the flexibility in the system to accomplish this SOR without jeopardizing the April 10th rule curve elevations called for by the Biological Opinion;


2. Participants U.S. Fish & Wildlife Service, Idaho Department of Fish and Game, Washington Department of Fish and Wildlife, Oregon Department of Fish and Wildlife, NOAA Fisheries, and the Columbia River Inter-Tribal Fish Commission.
3. TMT recommendation No consensus was reached issue was elevated to IT. The following question was raised Question for IT: Does the difference in the Fish Passage Efficiency noted in the 2004 hydroacoustic test results pose a "significant problem" which warrants spill this year? There was not agreement about this at the technical level and a request was made to elevate the issue for policy level consideration.
4. AA decision  
5. IT recommendation The COE will implement the operation with no spill. TMT was asked to confer on Monday with the specifics of the operation. While there was not agreement on the issue, it was not elevated to the regional executives.
6. AA decision (after IT)
 See above
7. Actual Operation Operation was implemented as requested except that no spill was provided. Operation ran from 0700 hours Friday, 3 March - 1100 hours Tuesday, March 7. based on estimates that more than 95% of the fish released have passed the project. The minimum tailwater was 12.5 ft instead of the requested 14.5 because without spill the higher elevation was not needed. This was agreed to during a conference call.
