Project / Study Area
BUILDING STRONG®
Background 2000 USFWS Federal Columbia River Power
System (FCRPS) BiOp.►Requires Corps to study feasibility of fish
passage at Albeni Falls Dam Studies & Expert Workshops:
►Radio Telemetry Studies & Genetic Testing ►Expert Fish Passage Workshop ►Bull Trout Regional Workshop ►Kalispel Tribe Temporary Denil floating trap
BUILDING STRONG®
Problems & Opportunities Problems:
► Entrained bull trout cannot access high quality habitat.► Entrained bull trout cannot access cold water refugia.► AFD is projected to be the last barrier in the Pend
Oreille and Clark Fork river basin system.
Opportunities:► Reestablish habitat connectivity for bull trout.► Leverage system-wide restoration activities to develop
a comprehensive and regional restoration initiative.
BUILDING STRONG®
Project Scope Purpose: Restore connectivity & ensure
safe, timely, & effective upstream passage of adult and sub-adult bull trout Project Phase: Feasibility level decision
document• Integrated Post-Authorization Decision Document
/ Environmental Assessment (PADD/EA).• Corps has existing construction authority
Proposed Alternative: Trap & Haul Facility
BUILDING STRONG®
Project Schedule AUG 17: Biological Assessment submitted SEP 17: Draft PADD/EA complete OCT 17: Public Review Period JAN 18: Consultation Complete SEP 18: Final PADD/EA approved FY19: Secure Federal funding FY20-21: Design Phase FY22: Earliest construction start date

Trap & Haul Facility Benefits
►Prevents fall back from occurring►Shorter ladder is more advantageous for
sub-adult bull trout►Transport of fish upstream to safe release site►Avoids dam safety impacts►Opportunity for sorting for fish management

Natives to Forebay
Non-natives to Tailrace

Operations – Proposed Action
Year Round Operations, except for:► Extreme ice events (DEC – FEB, < 3o C)► Extreme late summer temperatures (AUG > 20o C)
Sorting facilities to visually inspect & separate:► Bull trout for release upriver► Native species for release in the forebay► Non-native species for release in the tailrace
Trestle Creek Bull Trout
BUILDING STRONG®
Operations – Proposed Action Two years of post-construction monitoring:
► Identify injury and mortality ► Ensure effective passage► Ongoing - Species counts and disposition
Fish managers would have access to the facility for Research, Monitoring and Evaluation (RME)► Control of non-native/invasive species movement.► Elective disease or genetic sampling
