Purpose and Approach Metrics Summary Adaptive Management Moving Forward

Purpose and Approach

Summarize how well the combined program has achieved the mitigation objectives

Highlight achievements and limitations observed over the program history

All metric definitions were agreed upon by data contributors from each program

Data displayed as: Combined averages across all programs Data series from individual programs to show patterns and

variation for each metric across programs I will not focus on or address nuances between programs

Mitigation Goals

Program represents a large geographic area

Majority of program resources are focused on harvest mitigation

Original planning included: 11,020,000 smolts at 8/pound 0.5%SAR for 55,100 to project area 1.5% SAS for 165,300 total mitigation

Smolt Releases

Original modeling 11,020,000 Smolts at 8/pound

Current Smolt Releases 5,350,000 Smolt size- 4.5 to 5 fish/lb

Some of the programs have reduced the number of smolt releases for specific management purposes.

Other programs are not able to achieve the targeted number of smolts due to water limitations

Maintaining Historic Fisheries

Harvest- Above project area

Maintaining Historic Fisheries

Angler Effort The number of “Angler Days” fishing for steelhead has

increased across all programs from the pre-mitigation period

Angling Opportunity Number of days open to fishing for steelhead

Did not change significantly over time Maintained abundant opportunity

212-271 days open to fishing Number of miles open to steelhead fishing

Minor changes in some areas (+ or -) Significant decreases in other areas

Summary

Primary focus of LSRCP steelhead program is on harvest mitigation

Ability of supplementation programs to provide conservation benefits is being evaluated

Post release survival is highly variable but shows synchrony between programs

Overall adult production goal has never been achieved

Escapement goal to project area has been achieved in nine years through 2009

Summary

Contribution to downstream fisheries is less than was anticipated during program development

Hatchery mitigation program has provided consistent robust recreational fisheries above the project area

Angler effort and harvest in the project area has increased since the pre-mitigation period

Hatchery programs provide abundant opportunity for anglers and significant economic benefits to local communities

Summary

Straying is variable across programs We have shown you the range of observed stray rates

but difficult to interpret impacts on natural populations PITs and PBT can provide additional information

Significant increase in the effort to monitor the status and trends of natural populations

Adaptive Management

Acclimation Size at release Reduction in number of smolts released Consolidation of release sites Brood Stock Collection

Endemic Locally adapted Fall Collection Trapping infrastructure

Moving Forward Continue monitoring production and productivity of

hatchery populations. Evaluate methods to increase SASs Continue efforts to evaluate hatchery tool to provide

conservation benefits Continue efforts to reduce impacts of hatchery program

on natural populations while maintaining the successful harvest mitigation program

Run reconstruction workgroup at LGD Snake R. basin co-managers Accounting of LGD escapement

Existing and new work to increase information base on status and trends of natural populations

Coordination and collaboration
