Abstract: The new second powerhouse at the Rock Island Dam will contain eight of the world's most powerful bulb units, rated 71,000 HP each at a net head of 39.7 ft (12 m). By raising the reservoir 6.1 ft (1.86 m) and increasing the project's hydraulic capacity to about 220,000 cfs, maximum production of power from the available Columbia River waters will be achieved. The proposed expansion will have minimal effects on the existing spillway, fish passage facilities, and a possible future navigation lock.
