  1. Acoustic Telemetry evaluation of juvenile fish-passage efficiency and survival associated with surface-spill treatments at john day dam in 2010 Mark Weiland, James Hughes, Gene Ploskey, Daniel Deng, Christa Woodley, Tom Carlson-PNNL -PSMFC Rich Townsend, John Skalski-University of Washington Portland District, USACE Brad Eppard (COTR)

  2. Objectives • SPRING (Yearling Chinook and Steelhead) • Compare survival rates associated with 30 and 40% spill treatments • Two 2-day treatments within 4 day blocks • Calculate single release survival estimates from concrete at JDA to The Dalles Dam • Evaluate passage efficiency of the spillway and two top-spill weirs (TSW) in spill bays 18 and 19 • Evaluate survival of smolt passing at spillbay 20 with a modified deflector 2

  3. Objectives • SUMMER (Subyearling Chinook) • Compare survival rates associated with 30 and 40% spill treatments • Two 2-day treatments within 4 day blocks • Calculate single release survival estimates from concrete at JDA to The Dalles Dam • Evaluate passage efficiency of the spillway and two top-spill weirs (TSW) in spill bays 18 and 19 • Evaluate survival of smolt passing at spillbay 20 with a modified deflector 3

  25. Summary • There was not a significant difference in survival between 30% and 40% spill treatments for steelhead, yearling Chinook or subyearling Chinook • BiOp survival criteria (single release estimates to TDA) • Steelhead 96.1% - yes • Yearling Chinook 94.7% -no • Subyearling Chinook 90.8% - no • Spill passage efficiency (SPE) • Significantly greater in spring for both steelhead and yearling Chinook • No significant difference for subyearling Chinook • Surface outlet efficiency (SOE) i.e.TSW efficiency • Significantly greater in spring for both steelhead and yearling Chinook • No significant difference for subyearling Chinook

  26. Summary Minor tag-life correction for steelhead and yearling Chinook No tag-life correction for subyearling Chinook

  27. Conclusion • Not a significant difference in survival between 30% and 40% treatments • TSW’s in spillbays 18 and 19 • Improved passage and survival in spring (surface oriented fish) • Attracted subyearling Chinook in summer but lower survival rates than unmodified spillbays (oriented deeper) • Modified spillbay 20 • Survival at spillbay 20 with modified deflector not as high as unmodified spillbays (better than 2008 and 2009 in spring, possibly due to hydraulic conditions
