20 Nov 2007 2007-FWS2 FWS Winter Temperature Operation of Libby Dam for Kootenai River burbot
1. SOR request Specifications:
FWS in cooperation with Kootenai Valley Resource Initiative request that USACE use selective withdrawal gate system at Libby Dam to release the coolest water possible in November & December 2007 before temperature stratification limits the temperature control capability. Purpose is to provide cooler river temperatures downstream of Bonners Ferry, and also to determine how radio-tagged burbot in Kootenai River respond to these temperatures. Temperature rule curve deviation has been coordinated with Montana Fish, Wildlife & Parks. Corps at Libby Dam will remove selective withdrawal gates incrementally to assure that daily temperature change remains within 2 degrees F per day; gates should be removed systematically during October to slowly lowever river temperature to the minimum by November 1 (on average, a span of about 5 degrees C, or 9 degrees F.

2. Participants U.S. Fish and Wildlife Service
3. TMT recommendation Implement the operation as specified.

6. AA decision (after IT)
 
7. Actual Operation The Corps began removal of the remaining selective withdrawal gates (13 of 18 rows remained in place after spring and summer temperature management) on October 1st, and completed removal of all gates by October 23rd. Beginning gate elevation was 2,357' when the pool was at ~2,435' (2,459' is full pool); ending gate elevation was 2,222', with the pool remaining essentially unchanged during the removal period. Initial release temperature on October 1st was ~ 54 F, and was lowered to ~ 45 F by October 23rd. From October 23rd until the end of the SOR period temperature from Libby Dam was minimized to the extent possible via selective withdrawal gate capabilities.

26-June-2007 2007-07 USFWS, ODFW, WDFW, NPT, CRITFC Libby 2007 and Hungry Horse Summer Operations
1. SOR request Specifications:
Provide Outflows from Libby and Hungry Horse dams over July and August as estimated in the last (6-26-07) STP to draft these reservoirs to 20 feet below their full pool elevations by August 31, followed by a gradual ramp down of flow through the first week of September. The current STP estimates an outflow from Libby of 17.4 Kcfs while drafting to elevation 2439 feet (20 feet from full) and outflows of 4.4 Kcfs from Hungry Horse while drafting to elevation 3540 feet (20 feet from full). If near term COE water forecast and flow predictions show that these recommended outflow levels will leave these reservoirs above the 20-foot draft level by the end of August, we request that the volume of water predicted to be left in the reservoirs above the 20-foot draft level by August 31, be provided from other storage water releases, such as from Canadian sources, in the July-August migration period. Should Non-Treaty water become available for flow augmentation later in the summer, these recommended releases from Libby and Hungry Horse can be modified to reflect the change in water availability such as was accomplished in 2006.

Implement the Biological Opinion default operation to reach reservoir elevation 20 feet from full by August 31 at Libby and Hungry Horse Dams. However, Montana objected to this operation and requested the issue be elevated to the Regional Executives level for decision as soon as possible. Regional Executives decision was to implement the CRITFC/Nez Perce/OR/USFWS SOR for 2007, as a default BiOP supported operation. Federal executives present at that meeting expressed support for implementing the Montana proposal per the Mainstem Amendment recommendations in the future, and for including discussions of this issue through the Remand process, as it is supported by ISAB review and supports listed fish.

12-June-2007 2007-MT-1 Montana Fish Wildlife & Parks & Kootenai Tribe of Idaho Libby & Hungry Horse Operations for July through September
1. SOR request Specifications:
Hungry Horse
  • Attempt to refill by June 30 while also avoiding the risk of filling to quickly resulting in uncontrolled spill. Even small amounts of spill will likely exceed Montana's water quality regulations for 110% dissolved gas. Therefore, the refill date and outflows should be managed to avoid, if possible, uncontrolled spill.
  • Assuming that Hungry Horse refills in late June or early July it will be necessary for Reclamation to pass inflows until they drop below the desired flat flow of 4.0 kcfs1. For the remainder of July, August and September target a flat flow of 4.0 kcfs.
  • Maintain minimum in stream flows for bull trout at Columbia Falls and in the river below Hungry Horse dam.
  • Attempt to provide stable or, if necessary, gradually declining flows at Columbia Falls.
Libby
  • Following the May-June flow operation for sturgeon, continue the flat flow target of 15.0 kcfs1 through July 21st or until the core sampling in the Bonners Ferry area is complete. Based on recent runoff volume forecasts it appears that it will be necessary to reduce flows to 12 kcfs for the remainder of July and August.
  • Montana the Kootenai Tribe of Idaho and the Corps will review this operation, actual runoff volumes and resulting reservoir elevations. By the middle of July this SOR's flow request for the remainder of July, August and September may need to be modified. If modification is necessary, a recommendation will be brought to TMT for discussion and resolution.
  • Water conditions this year make it unlikely that the Corps will be able to refill Libby therefore; refill is lower priority than providing flat flows in the most productive summer months.
  • Operate to provide at least minimum bull trout flows through September (USFWS BiOp).
Biological Evaluations

Montana Fish Wildlife & Parks has a range of field experiments that will provide useful information on the changes in survival and productivity of trout below Libby and Horse reservoirs. These experiments will be continued and to the extent possible provide additional biological information on the benefits of the proposed operation for resident fish.

Radio tracking and PIT tag methods will continue in the Flathead and Kootenai Rivers to detect movements and potential downstream displacement of fish. This will allow a comparison of changes in fish movement and response to flow fluctuations caused by the dam operations called for in this SOR.

IFIM river models, benthic biomass models and reservoir modeling will compare previous operations with modified operations. Field observations will be conducted to see how fish respond to new operations to determine any changes from previous measurements.

Using the existing biological models the proposed operations will be evaluated to determine changes in river and reservoir productivity and these simulations will be validated with field sampling.

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.

11-May-2007 2007-FWS1 USFWS 2007 Libby Dam Releases for Sturgeon and Bull Trout Augmentation Flows
1. SOR request Specifications:
Based on the May final April-August volume runoff forecast of 6.990 million acre-feet we are within a tier 4 operations year for Kootenai River white sturgeon as defined in the Fish and Wildlife Service's February 2006 Biological Opinion (2006 BO) on operations of Libby Dam. The minimum recommended release volume for sturgeon conservation under these circumstances is 1,170 thousand acre-feet, and we now recommend the following procedures for discharge of at least this minimum volume from Libby Dam:

Ascending limb of hydrograph: Once Kootenai River temperatures at Bonners Ferry reach 8° C, and Koocanusa Reservoir warms such that 20-25 thousand cubic feet per second can be released through the turbines without decreasing Kootenai River temperatures by more than 1.5° C, increase flow at Libby Dam to 20 thousand cubic feet per second (according to ramping rates in the 2006 BO); the ramp up should begin at 6:00 AM on the initial day.

Peak of hydrograph: Ninety six hours (4 days) after the start of the above flow increases, at about 6:00 AM, increase flow at Libby Dam to 25 thousand cubic feet per second. No load following should occur during this period of peak flows. Maintain 25 thousand cubic feet per second flow out of Libby Dam for 14 days.

Descending Limb of the Hydrograph: At about 6:00 AM following 14 days at full discharge, discharge from Libby Dam can be reduced (following prescribed ramping rates) to 20 thousand cubic feet per second. However, this discharge rate may be continued if necessary to reduce the rate of reservoir refill to avoid a double peak following the spring freshet. Note: The intent is to delay reservoir refill until inflows decline below turbine capacity.

At about 6:00 am after three days at 20 thousand cubic feet per second, ramp Libby Dam discharge downward to a minimum of 15K cfs.

Use the remainder of the tiered volume of 1,170 thousand acre-feet to assure a gradual decline from the spring freshet and avoid a double peak. However, this discharge rate may be continued for additional days if you elect to provide sturgeon flow in addition to the minimum recommended.

Provide stabile or gradually declining discharge through the end of September.

Additional recommendations may be provided as water supply forecasts are updated. However in the absence of this clarification, beginning approximately June 15, 2007 we recommend that at least the tiered bull trout minimum flow of 9,000 cfs from the 2006 BO be maintained through September.

26-Apr-2007 2007-05 ODFW, WDFW, IDFG, NOAA Fisheries, USFWS, SBT, CRITFC Bonneville Dam Operations for Spring Creek Hatchery Release on May 1, 2007
1. SOR request Specifications:
  1. The Salmon Managers listed above request the Action Agencies to operate the units at Bonneville Second Powerhouse equipped with gap closure devices, at the low end of the 1% efficiency range. This operation should be implemented beginning at 0001 hours on May 2 and continue for 72 hours, or longer, if the majority (95%) of Spring Creek Hatchery fish continue to pass the project.
  2. If mortality rates in the sample at any time meet, or exceed 2%, spill should be increased from the 100 Kcfs to the level of the gas cap spill.
2. Participants Oregon Department of Fish and Wildlife, Washington Department of Fish and Wildlife, Idaho Department of Fish and Game, NOAA Fisheries, US Fish and Wildlife Service, Shoshone-Bannock Tribes, and the Columbia River Inter-Tribal Fish Commission.
3. TMT recommendation Implement the SOR
4. AA decision Implement the SOR to operate those units in powerhouse two with modified gap closure devices at the lower end of 1%
5. IT recommendation  
6. AA decision (after IT)
 
7. Actual Operation Started the operation at 1201hours on May 2 and on May 4 the USFWS requested that the operation continue past the planned 72 hours for an additional 8-hours as described in the SOR. The COE agreed to extend the operation to ensure that 95% of the Spring Creek hatchery fish passed the project.
8. If different from AA decision, why?

Bonneville Dam Operations

1. SOR request Specifications:
Beginning immediately, spill at Bonneville Dam to provide an alternate route of passage from the bypass system in order to spread-the risk at the project. Continue the spill operation until the Bonneville Dam bypass system has been eliminated as a source of the recent increased mortality rates for listed Spring Creek National Fish Hatchery subyearling fall chinook. Spill a minimum of 85 Kcfs at Bonneville Dam, using a minimum 2-foot spill gate opening at each spillbay. Continue until 95% of the Spring Creek hatchery releases have passed, likely this will occur by Wednesday morning March 14, 2007.
2. Participants U.S. Fish & Wildlife Service, Oregon Department of Fish and Wildlife, the Washington Department of Fish and Wildlife, NOAA Fisheries, Shoshone-Bannock Tribes, and the Columbia River Inter-Tribal Fish Commission (Due to the 2007 Operations Agreement between BPA and the CRITFC Tribes, we cannot support the SOR but will not oppose the SOR).
3. TMT recommendation TMT recommended spill of 85 kcfs and operate the corner collector to spread the risk as stated in the SOR. However, information provided by NOAA-F during the TMT call resulted in the Corps continuing with the existing operation of the corner collector only, with no spill. TMT agreed to continue with the monitoring of fish mortalities at the Juvenile Monitoring Facility (JMF) and in the event of increases in mortalities at the JMF; reconvene a TMT meeting as soon as needed and discuss the SOR.
4. AA decision Continue to operate corner collector for spring creek release w/o spill
5. IT recommendation  
6. AA decision (after IT)
 
7. Actual Operation Operate corner collector for spring creek release w/o spill. TMT did not reconvene due to declining mortalities reported by the Juvenile Monitoring Facility.
8. If different from AA decision, why?
