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

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

5 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 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 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

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 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
