The Yuba-Bear Hydroelectric Project is a complex hydroelectric scheme in the northern Sierra Nevada in California, tapping the upper Yuba River and Bear River drainage basins. The project area encompasses approximately {{convert|400|mi2|km2}} in Nevada, Placer, and Sierra Counties. Owned by the Nevada Irrigation District, it consists of 16 storage dams plus numerous diversion and regulating dams, and four generating stations producing 425 million kilowatt hours of electricity each year.

Project features

The main water sources for the project are the Middle Yuba River, and Canyon Creek (a tributary of the South Yuba River. Jackson Meadows Dam stores water from the Middle Yuba, which is diverted southward through the Milton-Bowman Diversion Conduit into Bowman Lake, an impoundment of Canyon Creek. In addition to Jackson Meadows and Bowman reservoirs, the Yuba-Bear project derives water from fourteen smaller high elevation Sierra lakes, which have been dammed to increase their size.^[1]

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.^[1]

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. The Yuba-Bear project operates two of these plants (Dutch Flat No. 2 and Chicago Park), in addition to a smaller powerhouse below Rollins Dam.^[1]

Together with the Drum-Spaulding Project, the Yuba-Bear project is considered by the Federal Energy Regulatory Commission to be "the most physically and operationally complex hydroelectric project in the United States".^[2]

History

The Yuba-Bear project was incepted in 1962 when NID voters approved a bond issue to construct the system. Construction began in 1963 and was completed in 1966, at a cost of $65 million (${{formatprice|{{Inflation|US-GDP|65e6|1966}}}} in {{Inflation-year|US-GDP}} dollars{{Inflation-fn|US-GDP}}). The Rollins Dam and Bowman power plants were added in the 1980s.^[3][4]

Uses

At maximum capacity, the project can generate 79.32 megawatts. Power is distributed under contract with Pacific Gas and Electric (PG&E).^[5] The project's reservoirs have a gross storage capacity of {{convert|203865|acre feet|km3}}.^[6]

In addition to hydroelectric power, the project significantly increases the water flow in the Bear River, the main source of NID's irrigation water supply.^[6]
