Agnew Lake (California)

Agnew Lake is a small reservoir located in the Sierra Nevada mountains of California, within the Inyo National Forest and Mono County. It is part of the Rush Creek Hydroelectric Project, owned and operated by Southern California Edison (SCE).

The lake is formed by Agnew Dam, a concrete arch dam built on Rush Creek in the early 20th century. Its primary purpose is water storage for hydroelectric power generation at the Rush Creek powerhouses downstream. Agnew Lake is situated above Gem Lake and below Waugh Lake, all interconnected as part of the Rush Creek system.

Recreational opportunities at Agnew Lake are limited primarily due to its relatively small size and challenging access. The lake is typically reached via the Pacific Crest Trail or connecting trails. Backpacking and fishing are possible, though requiring backcountry permits and adherence to regulations of the Inyo National Forest.

Water levels in Agnew Lake fluctuate significantly depending on seasonal snowmelt, precipitation, and the operational needs of the hydroelectric project. During the late summer and fall, the lake can be drawn down considerably, sometimes exposing large areas of its lakebed. This fluctuation can impact fishing and aesthetics.

The lake and surrounding area are known for their scenic beauty, including granite peaks, alpine meadows, and stands of pine trees. The area is also home to a variety of wildlife, including deer, bears, and various bird species.
