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) Dave Statler (Nez Perce Tribe) Erick Van Dyke (ODFW) Erin Cooper (FPC) Jennifer Graham (Warm Springs Tribe) Kyle Dittmer (CRITFC) Margaret Filardo (FPC) Rick Martinson (PSMFC/SMP) Russ Kiefer (IDFG) Trevor Conder (NOAA) AGENDA ITEMS Approval of Notes FPAC notes from June 28 were changed to reflect 65 o F or 66 o F regarding temperature management at Lower Granite. Water Supply/Flood Control G:\STAFF\DOCUMENT\2016_Documents\2016_Files\FPAC\0706\FPAC Action Notes July 6_Revised2.doc

2 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. Weather Kyle Dittmer (CRITFC) provided a summary of weather conditions and water year status. See attached. Juvenile Fish Passage Status For passage indices on July 6, 2016, please see the attached document. For updated indices, use the FPC website. Adult Fish Passage Status For adult counts on July 6, 2016, please see the attached document. For updated counts, use the FPC website. Brandon presented graphs showing forebay temperature and adult sockeye counts at BON, MCN, PRD, and IHR. Per FPAC s request, Brandon will circulate these graphs to the group after the meeting. Temperature For daily temperatures from and year-to-date temperatures, please use the FPC website ( FPAC discussed Little Goose ladder temperatures and differential between entrance (S4) and other monitors (S1-S3). Ladder temperatures were available through June 29 th on the FPC website ( From June 26-29, temperature differential between entrance (S4) and other monitors (S1-S3) was up to 5 F. Cooling pumps at Little Goose were turned on at 11:00 am on July 1 st. Ladder temperatures during the operation of the pumps should be available later this week. Spill Update For spill and TDG from June 28 to July 5, please see the attached document. For updated information, please use the FPC website. Spill at LGR was less than 18 Kcfs for several hours on June 29 th. This period of reduced spill occurred just after RSW was taken out of operation. On morning of June 28 th ( ), spill of 85 kcfs was provided at BON instead of FOP prescribed 95 Kcfs. Paul Wagner (NOAA) will inquire as to why this occurred. On July 5 th, flows at LMN were reduced in the afternoon. This reduction in flows resulted in spill of less than FOP prescribed 17 Kcfs. Flows were increased later in the afternoon and 17 Kcfs spill was again provided. Russ Kiefer (IDFG) pointed out that, when flows increased in the evening, powerhouse flows exceeded ~12 Kcfs minimum. Page 2 of 4

3 FPAC discussed whether it was appropriate for flows to be reduced in the afternoon to a level that would result in reductions in spill in order to allow for increased powerhouse flows in the evening. Paul Wagner (NOAA) will inquire as to why this occurred. Dwoshak Operations Flows at Dworshak have dropped over the last week. The COE reviewed temperature models (available on the TMT website) and decided to decrease flows. FPAC members expressed concern that this operation was not discussed with fisheries managers prior to implementation. Paul Wagner (NOAA) explained that the COE will make decisions based on models, and if FPAC disagrees, they can request a change of operations, as coordinated at TMT. Margaret Filardo (FPC) pointed out that the proposal to drawdown the Dworshak reservoir (to some level below 1520 ) was discussed last week, with no decision. Paul Wagner (NOAA) stated that due to various potential objections, the proposal should not move forward without stated interest by the Nez Perce Tribe. Dave Statler (Nez Perce) will update FPAC about the possibility of the Nez Perce Tribe wishing to move forward with the proposal. Most members of FPAC expressed interest in the proposal for some level of drawdown at DWOR. Russ Kiefer (IDFG) indicated that the state of Idaho will not support an SOR for drawdown of DWOR below 1520 in 2016 because 1520 assures a 95% probability of refill and the COE does not plan to draft below 1520 for flood control. The FPC pointed out that refill was not jeopardized in the analysis conducted. It is possible that the analysis conducted by FPC may not be fully understood. Margaret Filardo (FPC) reminded FPAC of the June 24 FPC memo about the potential of using Lower Granite Reservoir Drawdown to better meet water quality standards for temperatures below LGR and perhaps in the Lower Snake River. NOAA suggested that this alternative may be considered in the NEPA investigations in upcoming years. It was suggested that delaying this consideration into the years long process would remove a potential tool that could be used in 2 years time for reducing temperatures. The SOR conducted in the 1990s considered 2 years as an appropriate time frame to address considerations about drawdown implementation i.e. recreation, juvenile bypass, transportation and cultural resources. While it is agreed that modeling of the drawdown for temperature effects is necessary, it could be accomplished in a very short time frame (weeks as opposed to years). After lengthy discussion of concerns about impacts and timing, FPAC agreed that CE QAUL 2 should be used to model potential for LGR Drawdown on alleviating temperature concerns in the Lower Snake. However, there was no resolution as to who requests these modeling exercises and when. Bonneville Ladder Work Although the recent ROV survey eliminated some erosion concerns, the COE will be conducting an additional survey this Thursday, July 7. This survey will require four hours of no spill. Page 3 of 4

4 On July 8 th, the COE will implement a constant spill operation of 95 Kcfs, rather than alternating 95 Kcfs with days of 85 Kcfs/121 Kcfs. This constant spill operation will remain in place for the rest of the summer. This request may be reevaluated after the results of Thursday s survey are available. John Day North Ladder PIT-tag Detection A location has been found for the PIT-tag detection equipment at the north ladder of John Day Dam. Adult PIT-tag detection at JDA should be online in Spill Gate Minimums at Lower Granite Dam Erick VanDyke (ODFW) is considering an SOR that would request a 2-stop minimum in the spill gates at Lower Granite Dam. This will prevent spill dropping below 18 Kcfs under operations without the RSW and may result in spill of up to ~24 Kcfs. FPAC members will review the spill operations outlined in the FPP and discuss the proposal next week. August Transportation SOR Paul Wagner (NOAA) will contact the COE to find out the status of the August transportation SOR. He will update FPAC next week. Coordination FPOM will be this Thursday, July 7 th. The next FPAC conference call on Tuesday, July 12 th at 9:00 AM. The next FPAC face-to-face meeting will be on July 19 th, 2016, at 9:00 AM. These minutes have been reviewed and approved by the Fish Passage Advisory Committee. Page 4 of 4

Two 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.

27 Weekly Sockeye Report 7/5/2016 The entire sockeye run at Bonneville appears be on the declining phase of the run, having peaked around 6/23. Based on PIT tag counts at Bonneville, the Snake River Sockeye run also peaked around 6/24 and is on the declining phase of the run. Given current travel time, the peak of the Snake River Sockeye run Should arrive at Ice Harbor around July 3-4. All sockeye at Bonneville (window counts)

29 Adult Passage at Snake River Dams (window counts)

30 Water temperatures are approaching 20 C in the Snake and Lower Columbia Rivers, reduced Sockeye survival and increased fallback/straying have been observed at temperatures >18 C. However, no PIT tagged Snake River Sockeye have been detected crossing Priest Rapids dam, and fallback rates in the lower Columbia (BON-1.4%, TDA-7.6%, MCN-0%, DART) and Snake Rivers remain relatively low. There appears to be an increasing trend in fallbacks in the Snake River as temperatures increase as is typically observed. No fallbacks have been observed at Lower Granite through July 5. This is slightly lower than typical years and may be the result of the new temperature control structure for the ladder. However, fallback rates typically increase after July 1, so the next few weeks will give a better indication..

31 Survivals in the Lower Columbia and Snake Rivers remain at levels that would be expected with commercial harvest openings in effect. Sockeye began passing Lower Granite Dam on June 20, with a total of 252 passing through July 5. No PIT tagged sockeye have been observed at the Upper Salmon detectors yet, though the average travel time in 2014 was 20 days, so they should start showing up near the end of July.
