2 Lewis River Hydroelectric Projects SW Washington Swift No. 1 Merwin Yale 0 2 miles 4

3 Merwin Dam: 1931 Height: 313 Ft.

4 Yale Dam: 1953 Height: 323 ft.

5 Swift Dam: 1958 Height: 512 ft.

6 Project Background June 26, 2008 PacifiCorp and Public Utility District No. 1 of Cowlitz County received licenses from the Federal Energy Regulatory Commission (FERC)! Licenses include the Lewis River Settlement Agreement that contains 17 Sections and requires implementation of 69 measures Aquatics Terrestrial Species Recreation Cultural Resources Flood Management

7 Settlement Agreement Aquatic Enhancements Goal: Genetically viable, self- sustaining, naturally reproducing, harvestable populations of anadromous fish upstream of Merwin Dam.! Fish passage is key to achieving the goal. Installation of the Merwin and Swift Facilities opens up 117 miles of anadromous fish habitat upstream of Swift Dam.

8 Anadromous Fish Reintroduction - Stage 1; Phase 1 Hatcheries Separate out Hatchery Fish Haul Natural Adults to Swift Trap and Sorting Facility Trap Adults M e r w in Ya le S wi ft Collector and Sampling Facility Collect Juveniles FSC Haul Wild Juveniles to Release Pond Downstream of Merwin

45 Defining Roles and Responsibilities Who runs it? Fish Passage Team (Biologists) Fish Truck Drivers (Utility workers) Maintenance (Hydro Maintenance Crews) Engineering Support and Operations Key to smooth operation is open and direct communication

46 Defining Roles and Responsibilities Responsibility Matrix what needs to get done! Assigned tasks Who does the work?

47 Transfer of Knowledge Orientation and Training of PacifiCorp Staff! Ten Day Operational Test

48 Identifying Needs O&M Manuals!! Development of Maintenance Schedules based on manufacturers recommendations

49 Minimizing Risk Identifying Critical Alarms & Components! Remote Monitoring of FSC- Human/ Machine Interface

50 Lessons Learned Open communication is key Know your equipment Get training Understand your compliance metrics track results and address underperformance Be ready with Plan B On- call fish technicians Contracts with key maintenance vendors
