1 FISH PASSAGE CENTER 847 NE 19 th Avenue, #250, Portland, OR Phone: (503) Fax: (503) us at MEMORANDUM To: From: Fish Passage Advisory Committee (FPAC) FPC Staff Date: April 4, 2017 Subject: Action Notes from April 4, 2017, FPAC meeting On April 4, 2017, FPAC met via conference call for its weekly meeting. The following people participated in the meeting: Paul Wagner (FPAC Co-Chair NOAA) Tom Lorz (FPAC Co-Chair CRITFC) Brandon Chockley (FPC) Charlie Morrill (WDFW) Dave Benner (FPC) Dave Swank (USFWS) Erick Van Dyke (ODFW) Erin Cooper (FPC) Jay Hesse (Nez Perce Tribe) Jennifer Graham (Warm Springs Tribe) Kyle Dittmer (CRITFC) Margaret Filardo (FPC) Russ Kiefer (IDFG) Sheri Sears (Colville Tribe) Tom Iverson (Yakima Nation) Trevor Conder (NOAA) AGENDA ITEMS Approval of Notes FPAC notes from March 28 were approved without changes. Water Supply/Flood Control Dave Benner (FPC) provided a summary of the current reservoir operations and water supply forecasts, snowpack estimates, and ESP runoff volumes. See the attached document. G:\STAFF\DOCUMENT\2017_Documents\2017_Files\FPAC\0404\FPAC Notes April 4.doc

2 Paul Wagner has received an updated forecast for Hungry Horse. The April-August forecast is 2.23 MAF, 105% of average. Weather Kyle Dittmer (CRITFC) provided a summary of weather conditions and water year status. See attached. Juvenile Fish Passage Status For passage indices on April 4, 2017, please see the attached document. For updated indices, use the FPC website. Due to high flows and debris, the Snake River trap has been removed for the season. SMP sampling is currently every other day at Little Goose and every third day at Lower Monumental. PIT-tag detections at Lower Granite Dam starting on March 20 show passage of Dworshak hatchery releases. The Grande Ronde trap has collected Pacific ammocoetes, for the first time. Jay Hesse (Nez Perce Tribe) indicated that this may be due to adult lamprey transferred into the Grande Ronde a few years ago. All bypass systems are operating, with the exception of McNary. McNary will start between April 8 th and April 10 th. GBT sampling at Lower Granite started on March 30. Of a sample of 100 fish, 3 had level 1 (lowest rank) GBT in fins. Sampling will continue on every Thursday. o Brandon Chockley (FPC) will conduct GBT training tomorrow, Wednesday April 5. All other GBT sites will start sampling soon after. Little Goose will sample on April 7. Charlie Morrill (WDFW) pointed out that unlike steelhead, there are fewer yearling Chinook detections at Little Goose than at Lower Granite, indicating that travel times may be increasing after passing Lower Granite. Observation was based on FPC Cumulative PIT-tag Detection query ( Adult Fish Passage Status For adult counts on April 4, 2017, please see the attached document. For updated counts, use the FPC website. The FPC is still working with the COE to get updated adult counts on the FPC website. Automization is still a problem, due to security constraints. Spill Update For spill and TDG from April 3 to April 4, please see the attached document. For updated information, please use the FPC website. Page 2 of 5

3 Spring spill has officially commenced at all Snake River projects. Spill has largely been in excess of FOP spill levels due to limits of hydraulic capacity. TDG standards have been exceeded throughout the Snake and Middle Columbia rivers due to spill in excess of FOP. Bonneville Spill Proposal Paul Wagner (NOAA) presented a COE proposal on spill at Bonneville Dam. Margaret Filardo (FPC) clarified the proposal as she understood it. In the event that wind power generation slows, Bonneville must keep a certain amount of volume of water in reserve in the reservoir to increase power generation on short notice. Due to needs to keep the forebay elevation within a certain operating range, additional water will need to be passed as spill. o As an alternate operation, Scott Bettin (COE) has proposed operating Bonneville turbines outside the 1% efficiency range to move more water through the powerhouse rather than storing water. This would potentially reduce TDG. Paul Wagner stated that data will be available later today from the COE regarding the frequency of operation above the 1%. Paul Wagner stated that his understanding is that it is not used frequently and generally not for more than 2 hours at a time. Margaret Filardo expressed concern that by increasing the flow through turbines and operating outside of the 1% range, more fish will move through the powerhouse under conditions with higher mortality. By comparison, current TDG levels are not concerning. Margaret Filardo suggests not considering the proposal until TDG levels are near 130%. The reduction in TDG may be 2 3% under the proposed operation. Charlie Morrill (WDFW) stated that it is clear from the CSS workshop (April 3) that in order to reach Council recovery goals, fisheries managers should be minimizing powerhouse passage. Dave Swank (USFWS) stated they would like to have more information regarding the frequency and duration of the operation before making a decision. Margaret Filardo (FPC) stated that this operation is proposed at McNary and The Dalles due to their proximity to transmission lines, but concern that that it could be proposed at other projects in future. Sort-by-Code Request FPC members had no questions or objections for a Sort-by-Code request from Lance Clark (ODFW). Paul Wagner (NOAA) will approve the request later this week. Little Goose Operations Little Goose Dam has a need to operate at full pool, rather than MOP, in order to float a bulkhead in for repairs to the lock. Russ Kiefer (IDFG) suggested that rather than drawing down to MOP immediately after the floating of the bulkhead (April 12), delay the drawdown of the full pool at Little Goose to a time when drawdown volume could be used to maintain a uniform spill pattern at Lower Monumental. Uniform spill at LMN Page 3 of 5

4 is better for fish passage, and at high flows the higher elevation at Little Goose may not significantly impact travel times. Dave Benner provided the projected water travel times (WTT) at Little Goose under different operations. Flow (Kcfs) WTT at MOP (days) WTT at Full Reservoir (days) Margaret Filardo (FPC) recommended that if flows are around 130 or higher during the bulkhead operation, it might be better to drop to MOP at a rate of 5 Kcfs/day and maintain uniform spill at Lower Monumental. Flows can be monitored and the decision can be made based on current conditions. Transportation Start Date Paul Wagner (NOAA) stated that the default start date for transportation is May 1 st. He suggested that due to a lack of information regarding the potential benefit of early transportation, to fill out information a transportation study should transport fish from Lower Granite twice a week between April 20 and the official start of transportation. Russ Kiefer (IDFG) suggested that transportation once per week prior to the start of transportation may be sufficient. Margaret Filardo (FPC) reminded FPAC members that the transportation start date was moved from late April into May because data from NOAA showed that transportation benefit ratios were negatively impacted by the fact that fish transported early in the season did not do as well as those that migrated in-river. Tom Lorz (CRITFC) mentioned that since transport one day per week is the current research proposal, he wondered why Paul Wagner was advocating for more frequent transport. Paul Wagner replied that the current transport research only addresses fish tagged at Lower Granite, which are not directly comparable to fish tagged above Lower Granite, according to analysis by Steve Smith (NOAA). o Tom Lorz replied that with the high flows anticipated for this year, there is a low probability that enough tagged fish would be collected and transported to provide adequate sample size. Brandon Chockley (FPC) added that only tagged fish with the appropriate sort-by-code request would be transported rather than returned to the river. o Jay Hesse (Nez Perce Tribe) asked if information regarding sample size and required sampling rate is included in the proposed research. This information is not included in the one-page proposal. Coordination TMT tomorrow, Wednesday April 5. Page 4 of 5

20 * See sampling comments Smolt indices, clipped & unclipped or combined, are presented in the following order: yearling chinook (chinook 1's,) subyearling chinook (chinook 0's), steelhead, coho, sockeye, and lamprey juveniles. Three classes of fish counts are shown in these tables: Sample counts (Samp) are provided for juvenile lamprey at LGR. See note below for details. Collection counts (Coll), which account for sample rates but are not adjusted for flow; Passage indices (INDEX), which are collection counts divided by the proportion of water passing through the sampled powerhouse. Passage indices are not population estimates, but are used to adjust collection counts for daily fluctuations in the site's or project's operations. The classes of counts presented in the report are defined below for each site. Most samples occur over a 24-hr period that spans two calendar days. In this report, the date shown corresponds with the sample end date. Combined lamprey juvenile collection counts are provided for all sites. Combined lamprey juveniles is a combination of pacific lamprey ammocoetes, brook lamprey ammocoetes, unknown lamprey ammocoetes, pacific lamprey macropthalmia, and unidentified lamprey species. In 2013 it was confirmed that juvenile lamprey can escape the sample tank at LGR which would lead to unreliable estimates of collection. Therefore, only sample counts are provided in this report.

The WFA staff make every attempt to keep the counts as up to date as possible. Note: at WFA Monday's are extremely busy, as the staff attempt to catch up with the weekend counts. The Corp of Engineers has stopped shad counting at The Dalles, starting in 2011 on the advice of the Fish Passage Operations and Management (FPOM) committee, made up of NOAA, CRITFC, ODFW, WDFW, IDFW, BPA, and COE biologists. 1) Since the year 2006, Priest Rapids Dam and Wanapum Dam jack counts have included mini jacks. 2) Shad are not counted at Willamette Falls, The Dalles, John Day, Lower Monumental, Little Goose, Rock Island, Rocky Reach and Wells Dams 3) Steelhead counts appear higher at Lower Granite Dam because most years a group which migrated into the river system between October and December overwinters below LGR and continues its migration in early March. 4) As the Army Corp of Engineers no longer collects adult counts from the PUDs, we now get data directly from Chelan, Douglas and Grant Co. PUDs and DART. The steelhead counts include unclipped (wild) steelhead. It is not appropriate to add the steelhead counts and wild steelhead counts together. 5) Wild steelhead are counted separately from hatchery steelhead at Corps dams on the Columbia and Snake Rivers. Wild steelhead are identified as fish with an intact adipose fin. However, a small number of hatchery fish may not have had their adipose fin removed. There are no wild steelhead counts at Priest Rapids or Willamette Falls. Willamette Falls counts for: Chinook, Steelhead, and Coho only. 6) Shad are typically not counted at any of the Corps dams after August 31 each year and shad are not counted at all Corps dams. An n/a in the shad columns at Bonneville Dam and Lower Granite Dam after August 31st means that the shad are not being counted. 7) In 2014, Grant County PUD trapped and transported hundreds of Lamprey above Rock Island Dam. Therefore, the ladder counts of Lamprey at Rock Island under estimate the true numbers of lamprey past the project. When the source column on this report reads 'unknown', 'ceftp', or 'TMT', it is because the counts have been gathered via the phone or ftp and are considered preliminary data. When the Corp of Engineers finalizes the counts and posts them on their website the source reads USACE. This report includes ALL available adult counts. The information in this report is preliminary. In 2012, the U.S. Army Corps of Engineers and NOAA Fisheries are currently developing automated counting systems for Lamprey Passage Structures (LPS) installed at Bonneville Dam. In the interest of publishing accurate counts, LPS counts will not be publicly posted in season until the automated systems are fully operational. The adult counts in this report are based on reporting dates for dams recently established (2000). They are presented in the table below. A report with adult salmon counts based on historical dates (prior to 2000) can be found here. The reporting dates table shows that several dams stop counting fish around November 15th each year. After a dam stops counting fish for the season, only the total number of fish are shown on this report. These data are updated periodically throughout the day. The FPC data retrieving robot searches the web for updated data every 30 minutes in the AM, and every hour in the PM. ytd_adults.htm 2/3

23 4/7/ Day and YTD Adult Counts The last column " Source " shows where the data was imported from: NWACE is imported from the COE's Daily Fish Reports; USACE is from US Army Corps of Engineers fish count pages; CHPUD is from Chelan PUD; GCPUD is from Grant PUD and DGPUD is from Douglas PUD and DART is from the University of Washington's Data Access in Real Time, WFA is imported from ODFW's Willamette Falls website. Some of the sites are several days behind in reporting, but is reported by the COE as zero, so where zeros appear across all rows, the data should be considered as "not yet reported". Video counts can cause a delay in posting the data to the web, because the staff at the projects have to review the tapes Adult Salmon Dam Count Monitoring Dates Dam Bonneville Dam The Dalles Dam John Day Dam McNary Dam Ice Harbor Dam Video Monitoring Dates Day Night March 1 March 31, 2017 May 15 September December 1, , 2016 February 28, 2018 June 15 September 30, 2017 June 15 September 30, 2017 June 15 September 30, 2017 Direct Monitoring Dates April 1 to November 30, 2017 April 1 to October 31, 2017 April 1 to October 31, 2017 April 1 to October 31, 2017 April 1 to October 31, 2017 Lower Monumental Dam April 1 to October 31, 2017 Little Goose Dam Lower Granite Dam Priest Rapids Dam Wanapum Dam Rock Island Dam Rocky Reach Dam Wells Dam March 1 March 31, 2017 November 1 December 30, 2017 April 15 November 15, 2017 (24 hr) April 15 November 15, 2017 (24 hr) April 14 November 15, 2017 (24 hr) April 14 November 15, 2017 (24 hr) May 1 November 15, 2017 (24 hr) Willamette Falls Count year round (24 hr) June 1 September 30, 2017 April 1 to October 31, 2017 April 1 October 31, Columbia and Snake River Fishway Outages Dam Bonneville Dam The Dalles Dam John Day Dam McNary Dam Ice Harbor Dam Lower Monumental Dam Dates Fishways are Closed Bradford Island Fishway: Not Dewatering.

In January and February, Willamette Falls Dam is the only project that appears on the report because historically it collected data during this time period. End Date is the last day of data we have for that site the 2014 and 10 year average are also run to this end date. PRD is not posting wild steelhead numbers. These numbers were collected from USACE, Grant PUD, Douglas PUD, Chelan PUD, ODFW and DART. Shad data are not available at WEL, WFA, RIS, and RRH. Wild steelhead numbers are included in the total. Wild Steelhead are defined as unclipped fish. Historic counts (pre 1996) were obtained from CRITFC and compiled by the FPC. Historic counts 1997 to present were obtained from the Corps of Engineers.

29 Carrying non-spinning reserves above 1% at MCN and TDA. 3/30/17 Currently the Federal Columbia River Power System (FCRPS) is experiencing unusually high streamflows in excess of powerhouse capacities resulting in total dissolved gas (TDG) saturation levels exceeding the state water quality standards. These conditions are expected to persist at least through the month of April depending on streamflows. During this period BPA is attempting to fully load all of the available turbines to control TDG levels as close to the state standards as possible. Prior to April 1, the turbines were allowed to be operated up to full load. After April 1, turbine operations are restricted to operating within 1 percent of their peak efficiency. At McNary Dam and The Dalles Dam the 1% restriction results in a significant reduction the amount of water that can flow through the turbines. When streamflows are at more typical levels the restriction does not result in a noticeable change in spill at the dams. However, during very high streamflow conditions, such as is the case this year, the reduction in turbine flow exacerbates the already high TDG saturation in the river. Example: With the current high flows, restricting the flow through units to the 1% band will result in ~30-60 kcfs more spill at each of McNary and The Dalles dams. The increase in spill flow is estimated to raise the TDG saturations levels level 1-3% above current levels which are exceeding 120%. To maintain the reliability of the power system, a portion of the generation in the system must be held in reserve to account for unexpected increases in electricity demand, voltage or frequency. In order to provide the required reserves a generator must unload turbines to create unused capacity and make sure there is sufficient water available to utilize that capacity. A certain amount of these reserves must be available for deployment in seconds and are therefore required to be held on a generator that is already spinning. Some level of the required reserves can be non-spinning, meaning the reserves need to be deployable within 10 minutes. To maintain the required reliability of the power system at least half of the required reserves in the system must be spinning. BPA is proposing to use the system capability above the 1 percent operating range at McNary and The Dalles dams as a non-spinning reserve. If implemented, the ability to deploy non-spinning reserves in this manner will allow BPA to fulfill a portion of our reserve requirements and minimize spill above the state water quality standards. The operation will be rescinded when streamflows recede sufficiently to allow the reserves to be held within the FPP spill caps with the turbines operating within the established 1 percent operating range. If not implemented, in order to carry reserves, BPA will be required to further restrict the operation of units within the established 1 percent operating range, resulting in additional spill and increased TDG saturation levels above the state water quality standards until streamflows recede as noted above.
