Pelton Dam

Pelton Dam is a major dam on the Deschutes River in Jefferson County, Oregon, owned and operated as a hydroelectric facility by Portland General Electric, one element of its Pelton Round Butte Project on the Deschutes.

The lake has a surface area of about 540 acres (220 ha) and holds 33,190 acre-feet (40,940,000 m3) of water.

[2] Downstream, 2.5 miles (4 km) north, a regulating dam controls the river flow.

In 1982 the Confederated Tribes of Warm Springs installed a hydroelectric turbine unit in the regulating dam for additional power.

[3] Between 2000 and 2005 the CTWS also asserted itself as a stakeholder in the project's re-licensing negotiations between Portland General Electric and the Federal Energy Regulatory Commission, winning key environmental, cultural, and water rights concessions.
