LIMITING FACTORSTHE LOWER 30 MILES OF THE UMATILLA RIVER IS

HEAVILY DIVERTED FOR AGRICULTURAL USE

INADEQUATE FLOW

AND

PASSAGE IMPEDIMENTS

WERE PRIMARY CONTRIBUTORS TO THE EXTIRPATION OF SALMON AND DECLINE OF SUMMER STEELHEAD IN THE

BASIN

OBJECTIVEINCREASE THE SURVIVAL OF

MIGRATING JUVENILE AND ADULTSALMON AND SUMMER STEELHEAD

IN THE UMATILLA RIVER

GOALTO ASSIST IN THE RESTORATION OF

SALMON AND STEELHEAD IN THE UMATILLA RIVER BY INCREASING THESURVIVAL OF JUVENILE AND ADULT

MIGRANTS

APPROACH

TO MITIGATE FOR THE FLOW AND PASSAGE CONCERNS

IN THE BASIN, A THREE PRONGED PASSAGE

PROGRAM WAS IMPLEMENTED TO

ENHANCE PASSAGE CONDITIONS

PHYSICAL PASSAGE FACILITIES WERE CONSTRUCTED

JUVENILE SCREENS

ADULT FISH LADDERS

TRAP AND HAUL CAPABILITES WERE PROVIDED

TRAPPING FACILITIES

TRANSPORT EQUIPMENT

FLOW ENHANCEMENT EFFORTS WERE IMPLEMENTED

PHASE I EXCHANGE

PHASE II PUMPS

ASSUMPTION

BASED ON THE ABOVE ASSUMPTION, THE UMATILLA RIVER FISH PASSAGE

OPERATIONSPROJECT COORDINATES ALL THREE

COMPONENTS OF THE PASSAGE PROGRAM TO

MAXIMIZE THE TIME PERIODS AND OPTIMIZE PASSAGE CONDITIONS FOR NATURAL MIGRATION

NATURAL, VOLITIONAL MIGRATION OF UPSTREAM AND DOWNSTREAM MIGRANTS

IS PREFERABLE TO TRANSPORTATION AND HIGHER OVERALL SURVIVALS WILL RESULT IF ADEQUATE, NATURAL PASSAGE CONDITIONS

EXIST

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

ARTIFICIAL PROPAGATION ACTIVITIES

Broodstock collectionTransport 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

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
