2. Evaluate Performance objectives Gauge effectiveness of recovery measures Measure progress toward recovery and mitigation goals Maintain accountability Provide basis for adaptive management

3.  Hatchery Evaluation/Management Evaluate hatchery rearing and release strategies Estimate Contributions to fisheries Brood stock management Smolt-to-Adult Return Rates (SAR’s)  Wild/Hatchery proportions, pHOS  Run size and composition  Distribution and abundance (fisheries and on spawning grounds)

5. Mouth of Snake River (Col Rkm 522) Rkm 95 Rkm 173 Rkm 346 Hells Canyon Dam Rkm 397.4

6. Ice Harbor Lower Monumental Lower Monumental Little Goose Lower Granite Historical Fall Chinook Returns to the Snake Basin and timing of Lower Snake Dam Construction 1962-1985 (Ice Harbor Dam Window Counts)

7. Lower Snake River Fish and Wildlife Compensation Plan (LSRCP) - 1976 Mitigate for juvenile passage mortality and direct loss of spawning area for 5,000 fall Chinook Return 18,300 adults/year to the Snake River Basin In-place and in-kind (maintain genetic integrity)

9. Roles of Players in the Egg Bank Program Kalama Falls Hatchery Lower Columbia River Juvenile releases and collection of Returning Adults Ice Harbor Dam Lower Snake River Adult Collection Lyons Ferry Hatchery Lower Snake River Juvenile releases and Adult collection 1976 1986 Hagerman Hatchery Mid-Snake Juvenile releases Little Goose Dam

11.  9.16 million subyearling smolts (101,880 lbs) at 90 fpp (80 mm) expected smolt-to-adult return (SAR) of 0.2%  Idaho Power Co. mitigation for Hells Canyon Complex for 1.3 million eyed eggs due after LFH reached 80% of capacity

12. Very high stray rate—could jeopardize the SRF stock integrity

13.  1989 Brood Progeny Initiated 100% wire-tagging  Modified broodstock collection protocol LGR trapping Unmarked fish  Beginning in 1990, CWT’s were read prior to combining the gametes Fall Chinook trapped at Lower Granite Dam

16.  Yearling/Subyearling Comparative Survival Study (1985- 1990)  Snake River Fall Chinook ESA Listed as threatened in 1992  Fall Chinook Acclimation Program (FCAP)-1996

17. Subyearling Mean = 0.05 Yearling Mean = 0.59
