Xxxxxxxxx gave a brief summary of the ongoing Xxxxxx Dam Adult Trap Efficiency (ATE) Study for winter steelhead. So far, a total of 92 fish have been tagged (19 trap naïve vs. 73 trap non- naïve). Of the 19 trap naïve fish tagged downstream, 16 have returned to Xxxxxx Dam and all have been recaptured (ATETEST = 100%). All but one of the 73 trap non-naïve fish rereleased downstream have returned to Xxxxxx Dam and 63 have been recaptured (ATETEST = 88%). Further statistical analysis is still pending. Monitoring and data collection is scheduled through June 2018, with the draft report issued for review in early fall. As of end of April 2018, no adult spring Chinook have been transported upstream as part of the 2018 run year so far. By the end of April, there were approximately 360 adult spring Chinook being held at Xxxxx River Hatchery. These fish may be taken upstream once the returning run has reached the historic 50% level (generally around the 3rd week in May). A decision on whether to transport some or all of these fish will be made at that time. Additional details regarding this decision process can be found in Section B - 2.2 in the draft 2018 Hatchery and Supplementation Annual Operating Plan (AOP). Swift Floating Surface...
