1. UMATILLA RIVER FISH PASSAGE OPERATIONS
CONFEDERATED TRIBES OF THE UMATILLA INDIAN RESERVATION
In Conjunction with Oregon
Department of Fish and Wildlife

2. LIMITING FACTORS THE LOWER 30 MILES OF THE UMATILLA RIVER IS
HEAVILY DIVERTED FOR AGRICULTURAL USE

3. WERE PRIMARY CONTRIBUTORS TO THE EXTIRPATION OF
INADEQUATE
FLOW
AND
PASSAGE
IMPEDIMENTS
WERE PRIMARY CONTRIBUTORS TO THE EXTIRPATION OF
SALMON AND DECLINE OF SUMMER STEELHEAD IN THE BASIN

4. GOAL OBJECTIVE TO ASSIST IN THE RESTORATION OF
SALMON AND STEELHEAD IN THE
UMATILLA RIVER BY INCREASING THE
SURVIVAL OF JUVENILE AND ADULT MIGRANTS
OBJECTIVE
INCREASE THE SURVIVAL OF
MIGRATING JUVENILE AND ADULT
SALMON AND SUMMER STEELHEAD
IN THE UMATILLA RIVER

5. TO MITIGATE FOR THE FLOW A THREE PRONGED PASSAGE PROGRAM
APPROACH
TO MITIGATE FOR THE FLOW
AND PASSAGE CONCERNS
IN THE BASIN,
A THREE PRONGED PASSAGE PROGRAM
WAS IMPLEMENTED TO
ENHANCE PASSAGE CONDITIONS

6. PHYSICAL PASSAGE FACILITIES WERE CONSTRUCTED
JUVENILE SCREENS
ADULT FISH LADDERS

7. TRAP AND HAUL CAPABILITES WERE PROVIDED
TRAPPING FACILITIES
TRANSPORT EQUIPMENT

8. FLOW ENHANCEMENT EFFORTS WERE IMPLEMENTED
PHASE I EXCHANGE
PHASE II PUMPS

9. ASSUMPTION METHODS NATURAL, VOLITIONAL MIGRATION
OF UPSTREAM AND DOWNSTREAM MIGRANTS
IS PREFERABLE TO TRANSPORTATION
AND HIGHER OVERALL SURVIVALS WILL RESULT
IF ADEQUATE, NATURAL PASSAGE CONDITIONS EXIST
METHODS
BASED ON THE ABOVE ASSUMPTION,
THE UMATILLA RIVER FISH PASSAGE OPERATIONS
PROJECT COORDINATES ALL THREE COMPONENTS
OF THE PASSAGE PROGRAM TO
MAXIMIZE THE TIME PERIODS AND OPTIMIZE PASSAGE CONDITIONS FOR NATURAL MIGRATION

12. FISH PASSAGE ACTIVITIES
Monitor flows and river conditions
Operate and maintain passage facilities
Operate adult and juvenile trapping facilities
Continue flow enhancement efforts
Ensure adequate passage conditions exist

13. ARTIFICIAL PROPAGATION ACTIVITIES
Broodstock collection
Transport adults
The project collects and transports broodstock for the Spring chinook, Fall chinook, and summer steelhead programs.
Broodstock are collected under guidelines identified under Strategy 12,Action 12.1.
The project also transports surplus fall chinook adults from outside the basin for natural spawning supplementation and participates in other hauling efforts as needed

15. MONITORING AND EVALUATION ACTIVITIES
Monitoring of all adult returns at Threemile Dam
Operate smolt collection facilities
Support projects to reduce mortality related to Columbia River conditions
The project provides adult return data to both management and monitoring and evaluation projects
The project also provides data on juvenile outmigration timing
In addition, the project provides data for out of basin M&E efforts such as Gas Bubble Disease and Headburn studies and the U of I adult migration study

16. MONITORING OF
ADULT RETURNS
COLLECTION OF
CWT DATA
