3-May-2017 2017-FWS #1 U.S. Fish and Wildlife Service 2017 Libby Dam Releases for Sturgeon and Bull Trout Augmentation Flows
1. SOR Request SPECIFICATIONS:
Based on the U.S. Fish and Wildlife Services (Service) February 2006 Biological Opinion (2006 BO) on operations of Libby Dam, and the May final April-August volume runoff forecast of 8.19 million acre-feet (MAF), we are within a Tier 5 operations year for Kootenai River white sturgeon. The minimum recommended release volume for sturgeon conservation in a Tier 5 year is 1.2 MAF and we recommend the following procedures for discharge of at least this minimum volume from Libby Dam:

The precise means that will be utilized to meet these objectives are largely dependent on real-time conditions and in-season management. It is not possible to develop a single definitive recommendation for a sturgeon operation at this time due to the uncertainties in the forecast, and shape and volume of inflow. Given these uncertainties, the Service has developed the following guidelines for sturgeon operations in 2017:

o The 2017 sturgeon operations at Libby Dam will consist of one period of pre-peak flow (20,000 cubic feet per second (cfs)), one period of peak flow (powerhouse capacity), one period of interim flow maintenance (~18-21 kcfs at Bonners Ferry), a second period of peak flow (powerhouse capacity), and one period of post-peak flow (ramp-down). The ramp-down from peak operation will occur within 2006 BO ramping rates, and will exhaust remaining sturgeon volume following the second period of peak flow augmentation.

o Based on the Services 2006 BO on operations of Libby Dam, and the May final April-August volume runoff forecast of 8.19 MAF, we are within a Tier 5 operations year for Kootenai River white sturgeon. The minimum recommended release volume for sturgeon conservation in a Tier 5 year is 1.2 MAF, and we recommend the following procedures for discharge of at least this minimum volume:

o Begin sturgeon augmentation flow for the first peak when the Regional Team of Biologists determines that local tributary run-off downstream of Libby Dam is peaking.

o Increase discharge (according to ramping rates in 2006 BO) from Libby Dam up to full powerhouse capacity (~25,000 cfs), depending on local conditions (e.g. river stage at Bonners Ferry).

o Maintain peak discharge for a period of 5-7 days.

o Selective withdrawal gates at Libby Dam above elevation 2,326 mean sea level will remain uninstalled during this peak, allowing for conservation of warmer surface water that will be targeted for release during the descending limb of the second peak, described below.

o After 5-7 days of peak discharge, decrease discharge at Libby Dam (according to ramping rates in 2006 BO) to a discharge that is sufficient to maintain a flow of at least 18,000 cfs at Bonners Ferry until commencement of the second peak.

o Increase discharge (according to ramping rates in 2006 BO) from Libby Dam up to full powerhouse capacity when the Regional Team of Biologists determines that the high-elevation run-off in the Kootenai Basin has begun. Actual peak discharge during this second peak will depend on local conditions (i.e. river stage at Bonners Ferry).

o Selective withdrawal gates at Libby Dam above elevation 2,326 mean sea level will be placed to within 30 feet of the surface of the reservoir prior to the end of the second peak, described above, allowing for release of warmer surface water as the receding limb of the hydrograph commences. Release of warmer water from Libby Dam, in combination with lower volume of release, will allow the Kootenai River temperature to increase to appropriate spawning temperatures at Bonners Ferry (8-10 degrees C) during the receding limb of the hydrograph.

o Maintain peak discharge for a period of 7-14 days.

o After 7-14 days of peak discharge, and until the sturgeon volume is exhausted, decrease discharge at Libby Dam towards stable summer flows, to no less than bull trout minimum flows (9,000 cfs in Tier 5).

o Total number of days at peak discharge will depend on real time conditions and the shape of the inflow hydrographs.

As always, flood risk reduction operations supersede sturgeon flow augmentation, and dam managers will coordinate operations with regional sturgeon managers.

Sturgeon augmentation discharge may be extended for additional days if the Corps elects to provide volume in excess of the minimum volume requirement in the 2006 BO and to control the refill rate of Libby Dam.

Provide stable or gradually declining discharge through the end of September following ramping rates and minimum flow guidelines in the 2006 BO for bull trout and white sturgeon.

Additional recommendations may be provided as water supply forecasts are updated.

JUSTIFICATIONS:
The objective of the 2017 sturgeon augmentation operation described in this SOR is to provide two periods of peak river stages/flows during the spring run-off period. The first peak, timed to low-elevation run-off below Libby Dam, is intended to provide sturgeon cues to begin upstream migration and staging. The second peak, timed to high-elevation run-off above Libby Dam, is intended to provide sturgeon cues to migrate further upstream from their staging areas and spawn towards the end of the second peak and/or on its descending limb. Overall, the goal is to provide conditions that will enable sturgeon to migrate to, and spawn over, rocky substrates that exist upstream of Bonners Ferry.

This two-peak approach was successfully implemented in 2013 and 2014. Telemetry data for spawning Kootenai sturgeon females from those years indicate that a higher proportion migrated just upstream of Bonners Ferry than in recent years. A third year of single-peak sturgeon operations will allow sturgeon managers to test whether those results are due to the two-peak approach, temperature management, a combination of the two, or another factor.

The operating parameters outlined in this SOR are intended to provide some guidance on how to achieve the attributes listed in Table 1 of the 2006 BO, given the current water supply forecast. Previous years operations have shown that conditions at Libby Dam and in the Kootenai River basin can change rapidly. Recognizing this, the start date and exact shape of the operation will need to be developed and modified in-season as more is known. The in-season coordination will occur in the sturge on technical team and with a final recommendation coordinated through the action agencies and the Technical Management Team.

5. IT Recommendation  
6. AA decision (post IT)  
7. Actual Implemented Operation This years sturgeon operation involved two separate peaks in Libby Dam outflows. The first peak began on May 15, when Libby outflows of 16 kcfs were increased to 20 kcfs when local Kootenai River tributaries were forecasted to have peak outflows downstream of Libby Dam. Outflows were increased again between the dates of May 16 through May 21 when Libby maintained powerhouse capacity outflows of 24 kcfs. The end of the first pulse occurred on May 22 when Libby Dam outflows were reduced down to 18 kcfs. Libby Dam maintained these lower ouflows (18 kcfs) until the second pulse started on June 2 when Libby outflows were increased to 22 kcfs. Then Libby Dam maintained powerhouse capacity outflows of 25 kcfs June 3 through 11. The ramp down for the second pulse began on June 12 when Libby outflows were decreased to 22 kcfs. Subsequently ouflows were reduced to 20 kcfs June 13 through 15, and again down to 17 kcfs between the dates of June 16 through 18. The second pulse ended on June 14 when outflows were decreased to 14 kcfs.

A summary of Libby outflows during the sturgeon pulse are included below.

May 7 through 14: Prior to the 1st peak outflow was 16 kcfs

May 15: 20.0 kcfs (initiation of the first pulse)

May 16 to May 21: 24 kcfs

May 22 through June 1: 18 kcfs (1st pulse ended on May 22 when outflows were reduced to 18 kcfs)

June 2: 22 kcfs (initiation of the 2nd pulse)

June 3 through 11: 25 kcfs

June 12: 22 kcfs

June 13 through 15: 20 kcfs

June 16 through 18: 17 kcfs

June 20: 14 kcfs (end of the second pulse)

4-May-2017 2017-1 Kootenai Tribe of Idaho; Sue Ireland, Fish and Wildlife Department Director September through first week of November 2017 Libby Dam Outflow for Kootenai River Habitat Restoration Program, Lower Meander Project
1. SOR Request SPECIFICATIONS:
Release 6,000 cfs or less from Libby Dam during September through the first week of November, 2017.

Provide gradually declining discharge to the target flow following ramping rate guidelines in the 2006 USFWS BiOp for bull trout and white sturgeon.

JUSTIFICATION:
Low flows in the Kootenai River during September through the first week of November, 2016 are requested to allow the Kootenai Tribe of Idahos contractor to implement in-water work associated with the Kootenai River Habitat Restoration Program - Lower Meander Project during September through first week of November, 2016.

The purpose of restoration activities in the Lower Meander project area is to improve habitat conditions in the Kootenai River to help adult sturgeon migrate upstream, improve spawning habitat, increase juvenile rearing habitat, and improve overall ecosystem function. The strategy for this area includes: establishing a longitudinal sequence of high quality, deeper pools to support migration of Kootenai river white sturgeon to upstream habitats in the Braided and Canyon reaches; adding fill and plantings to existing islands to promote riparian development and provide food web support; grading and planting eroding banks to establish sustainable riparian buffers; installing bank structures to promote bank stability and to maintain pools; and installing woody debris structures in side channels and along bank margins to improve habitat complexity. The project will be constructed in two phases, the first of which will occur in 2017. The second phase of the project is scheduled for construction during 2018.

The proposed operation will ensure Action Agency compliance with the USFWS Biological Opinion regarding the Effects of Libby Dam Operations on the Kootenai River White Sturgeon, Bull Trout, and Kootenai Sturgeon Critical Habitat (1901F0279R) as clarified (2008). Action 2.1 under RPA Component 2 (Management of Sturgeon Habitat) calls for Action Agency cooperation in implementing the Kootenai Tribe of Idahos Kootenai River Restoration Project Master Plan.

3. TMT Recommendation The KTOI presented the SOR to the TMT during the meeting on May 10, 2017. Additional information regarding the operation may be found on the on the following website.

http://pweb.crohms.org/tmt/

May 10, 2017, TMT Meeting: The Kootenai Tribe, presented SOR-2017-1 which calls for 6kcfs or less outflow from Libby from September through the first week of November to allow for in-water habitat work. This is part of an ongoing effort since 2011 aimed at improving habitat for Kootenai River white sturgeon, including building spawning and rearing habitat. The construction this year will be finishing up the “pool-ladder” concept for the reach just upstream of Bonners Ferry. The KTOI noted that this work is implementing the USFWS BiOp.

14-June-2017 2017-C1 Jaime A. Pinkham, CRITFC Operation of the Lower Columbia Pools for the summer 2017 Treaty Fishery
1. SOR Request JUSTIFICATION:
The Columbia River Inter-Tribal Fish Commission, on behalf of its members, the Nez Perce Tribe, the Confederated Tribes of the Umatilla Indian Reservation, the Confederated Tribes of the Warm Springs Reservation of Oregon, and the Confederated Tribes and Bands of the Yakama Nation, requests the following reservoir operations in “Zone 6” (BON to MCN dams) during the summer 2017 Treaty fishery. This effort supports the 2017 ceremonial, subsistence, and commercial Treaty fishery times as set by the tribes and the Columbia River Compact.

The 2017 summer treaty fishing season is of critical importance to CRITFC’s member tribes. The run sizes (Columbia River at Bonneville Dam) of an estimated 59,700 (below average) adult summer Upper Columbia chinook and 198,000 sockeye (below average) will create harvest opportunities for tribal fishers who will exercise their treaty rights by participating in this harvest using platform and gillnet fishing methods. This harvest will provide for the cultural, religious, and economic needs of the treaty tribes.

CRITFC will sponsor net flights each week to count the set nets in each Zone 6 pool. The survey data will be shared with COE-RCC staff by early afternoon of the flight day.

Achieving good river conditions through managed river operations during the treaty fishery have been the basis of past litigation that have been supported by federal courts and are consistent with the trust and fiduciary responsibilities that the federal operators have with respect to CRITFC’s member tribes. Good river conditions during the treaty fishery are also consistent with the spirit of the 10-year Memorandum of Agreements signed by tribal and Corps, BPA, and USBR officials.

In past meetings with Corps officials, tribal fishers have explained that a pool fluctuation of more than 1.5 foot disrupts tribal fishery operations. Specific problems include: (1) increased local currents that sweep debris into fishing nets, (2) rapid 1-2 hour drops in water level will lead to entanglement of nets or change local currents that affect fishing success, (3) boat access problems, and (4) nets torn from their anchors if pools are raised after nets are set. Nets and gear are costly to replace and may become lost.

Any delays or disruptions to tribal fishing operations caused by the excessive pool fluctuations in Zone 6 can negatively impact tribal incomes, food resources and cultural practices. Much of the tribal fishers’ annual income and food is generated during the brief treaty fishing season. The fishers have expressed to Corps officials that the loss of fishing opportunity during the extremely limited treaty fishery period cannot be replaced.

If this SOR cannot be accommodated, CRITFC requests a verbal response with an explanation from the federal operators by COB, Friday, June 16, 2017. Thank you for considering this request. Please contact Kyle Dittmer or Stuart Ellis should you have any questions at (503) 238-0667.

SPECIFICATIONS:
Implement the following pool operations, as follows:

Monday, June 19, 2017, 6 am, through Thursday, June 22, 2017, 6 pm.

Monday, June 26, 2017, 6 am, through Thursday, June 29, 2017, 6 pm.

Bonneville: Operate the pool within a 1.5 foot band during the treaty fishing period.

The Dalles: Operate the pool within a 1.5 foot band during the treaty fishing period.

John Day: Operate the pool within a 1.5 foot band during the treaty fishing period.

CRITFC will notify the Corps with specific times for the tribal fishery after a Compact hearing.
2. Requester(s) Columbia River Inter-Tribal Fish Commission; Jaime A. Pinkham, Executive Director
3. TMT Recommendation The CRITFC presented the SOR to the TMT during the meeting on June 21, 2017. The CRITFC, provided an overview of the Treaty Fishing SOR on behalf of the Columbia River Inter-Tribal Fish Commission members. SOR 2017-C1 requests a 1.5 foot band for the Bonneville, The Dalles and John Day pools during the treaty fishing periods: June 19-22 and June 26-29. CRITFC noted that there will likely be subsequent requests for additional fishing periods. CRITFC shared that due to the run conditions, the fishing season will be shortened this year, likely concluding in mid-July instead of the end of July as normally occurs. The fall fishing season will begin in August.

The Corps implemented the SOR in coordination with the CRITFC and the TMT. Specific hourly data regarding these operations may be found on the following website. http://www.nwd-wc.usace.army.mil/dd/common/dataquery/www/

8-August-2017 2017-2 Port of Clarkston Lower Granite Dam Minimum Operating Pool
1. SOR Request SPECIFICATIONS:
Raise Lower Granite pool from Minimum Operating Pool (MOP) to MOP + 1 and hold for the 11 hour period from 0600 August 15, 2017 to 1700 August 15, 2017 before resuming normal operations.

JUSTIFICATIONS:
Economic impact: Cruise boats bring roughly 27,000 visitors and crew to the Lewis-Clark Valley every year. This tourist/recreation traffic has a significant impact on the local economy. Early to late fall are the busiest times. These domestic and foreign visitors are typically between 70 and 90 years old.

Preparation: The Port of Clarkston anticipated shoaling around its cruise boat facilities and developed alternatives for deeper draft cruise boats as sediment increases between dredging efforts. More sediment than anticipated arrived in 2017 as a result of a very rainy spring which caused flooding and erosion (see Attachment A). As a result, more cruise boats, even those with less deep drafts, have been impacted. On August 15, there are insufficient alternatives to accommodate all the scheduled moorings. By making shifts and adjustments, the Port has been able to make other dates with conflicts work and requested that cruise boats use less than optimal locations and hours for mooring. However, it was just discovered that the final, riskier alternative for mooring the boats has weak physical structure and should not be utilized.

Minimizing impact: Even the request for an 11-hour adjustment in MOP comes because cruise lines realize the importance of all the river operations and the need to conform with the Biological Opinion. With this ask, we have pared down the desirable pool adjustments to only that which is essential for the safety of passengers and the environment.

Going forward: As it expects cruise boat traffic to increase, the Port will explore any and all options for accommodating cruise boats in 2018 and going forward. The Port is seeking help from the Ports of Whitman County and Lewiston to identify additional berthing options. In addition, the Port of Clarkston will explore berth dredging because the cruise boat dock has been designed to assure safe over-the-water fueling, off-loading waste, etc. and is best suited, at this time, to meet passenger needs.

The Dalles: Operate the pool within a 1.5 foot band during the treaty fishing period.

John Day: Operate the pool within a 1.5 foot band during the treaty fishing period.

JUSTIFICATIONS:
The 2017 fall treaty fishing season is of critical importance to CRITFC’s member tribes. The run sizes (Columbia River at Bonneville Dam) of an estimated 400,600 (below average) adult fall chinook, 61,300 steelhead (below average), and 97,400 coho (near average) will create harvest opportunities for tribal fishers who will exercise their treaty rights by participating in this harvest using platform and gillnet fishing methods.

21-November-2017 2017-1 NOAA Fisheries; Paul Wagner Recommendation for Dworshak Operations (November-December 2017)
1. SOR Request SPECIFICATIONS:
Target end of December elevation of 1520’. Limit outflows up to powerhouse maximum with no spill.

We recognize that this has the slight potential to impact June refill. However, with current forecasts, the probability of impacting June refill is extremely low.

JUSTIFICATION:
Due to extended outage of Unit 3 and planned Unit 1 outage in January, we are concerned that reservoir volume may be such that spill in excess of 110% TDG may be necessary for flood risk management. In order to minimize the risk of this, we are recommending precautionary measures be taken in advance. Current predictions for La Niña water year increases the likelihood that 2018 will be above average.
