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

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

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
