Within the project period, staff coordinated with the USFS, IDFG, and NOAA-Fisheries to ensure all permits (SF-299, ESA Section 10, IDFG Scientific Collecting Permit, IDWR Stream Alteration Permit, and CORE 404 Permit) were valid to operate the project. The Tribes completed the 2016 BRCAMP Program – data collection, data analysis, and initiation of the Annual Report. The rotary screw trap was installed on 23 May and fished for 162 days until future removal on 31 October 2016 in response to freezing conditions. Thus far, preliminary 2016 outmigration estimates for juvenile Chinook salmon equals approximately 256,375; largest migrating life stage will likely be parr. To date, there are 1,403 Chinook salmon juveniles PIT-tagged for evaluation of migration timing and survival to the ocean, but tagging will continue until the trap is removed. All other non-target species were immediately enumerated and released downstream at the trap. The adult videography weir and PIT-tag antennas were installed on 14 June and removed on 10 September after seven consecutive days of no adult passages. Tribal staff preliminarily estimates a total return of 651 Chinook salmon to the watershed and 584 to the spawning grounds (corrected for harvest) that produced 314 redds (1.86 fish/redd). The final BRCAMP report will be submitted to NOAA Fisheries by 30 December 2016.

Project Benefit    

Bear Valley Creek is an important traditional use Chinook fishery area for the Tribes. It is extremely important to manage this Chinook salmon fishery based on the requirements of the ESA and the TRMP. Current abundance estimates, generated from redd counts show Bear Valley Creek Chinook salmon are at risk of extinction. Developing accurate adult abundance and productivity information will allow the Tribes and other resource managers to assess the effectiveness of conservation actions for listed Chinook salmon. Adult abundance information provides the Tribes the ability to conduct in-season harvest management (e.g., adjusting forecasts, harvest guidelines), which ultimately improves our ability to control Tribal harvest impacts on an ESA listed Chinook salmon. Juvenile abundance and PIT tagging data will allow the Tribes to further examine the productivity of Bear Valley Creek and enumerate the survival of Chinook salmon and steelhead as they travel through the Columbia and Snake rivers hydrosystem.

            The Tribes installed a rotary screw trap in Bear Valley Creek for the purposes of enumerating, tagging, and tissue sampling migrating juvenile Chinook salmon for research, monitoring, and evaluation purposes. The sample collection is valuable as results document the presence/absence of migrating juveniles and enables determination of age and size at migration, condition, timing, species, and genotypic characteristics. Additional data examines both migration timing and survival to and from the ocean.
