The powerhouse, with generating capacity of 1,807,000 kilowatts, is connected to the Pacific Northwest power system. During 1996 the powerplant generated 7.4 billion kilowatt hours, marketed by the Bonneville Power Administration and 16.5 million kilowatt hours used by the project. Construction and operating costs of the project's power facilities are repaid from those deposits. Facilities to move fish around the dam include two fish ladders, powerhouse collection systems and a transportation channel, and the lock. Each ladder is about one-third mile long.
Visitors can observe migrating fish at both ladders.
Recreation facilities have been developed in a number of areas near the dam and upstream along the river. Seufert Visitors Center was completed and open to the public in fall of 1980. Seufert Park on the Oregon shore, operated by the Corps, has a good view of the downstream side of the dam. A small train takes visitors from the visitor center to the powerhouse and dam. The Corps' Celilo Park, on Lake Celilo, has facilities for picnicking, fishing, swimming and boat launching.
