 After passing through Bowman Powerhouse, the water continues south via the Bowman–Spaulding Conduit to Lake Spaulding, which is part of the heavily interconnected Drum-Spaulding Hydroelectric Project owned by PG&E.Lake Spaulding is an impoundment of the South Yuba River, and is an important hub of the system as nearly all the water used by both projects passes through it.Below Lake Spaulding water passes through Drum-Spaulding Project canals through Emigrant Gap into the upper Bear River, where it powers six hydroelectric plants on its long descent to Rollins Reservoir, the lowermost major reservoir of the Yuba–Bear project.
