Located on the Middle Fork American River, and the Rubicon River, the Middle Fork American River Project (Project) affects 1,883 acres within the Tahoe National Forest and 1,385 acres within Eldorado National Forest, both of which are administered by the U.S. Department of Agriculture-Forest Service.

Primary Project facilities include: five powerhouses (French Meadows, Hell Hole Dam, Middle Fork, Ralston, and Oxbow Powerhouses); five diversion impoundments (Duncan Creek Diversion, North Fork Long Canyon Creek Diversion, South Fork, Long Canyon Creek Diversion, Middle Fork Afterbay, and Ralston Afterbay); five tunnels (Duncan Creek-Middle Fork, French Meadows-Hell Hole, Hell Hole-Middle Fork, Middle Fork-Ralston, Ralston-Oxbow Tunnels); and two reservoirs (French Meadows Reservoir, and Hell Hole Reservoir).

Currently, PCWA has water delivery contracts with the United States Bureau of Reclamation, San Juan Water District, the City of Roseville, and Sacramento Suburban Water District (formerly the Northridge Water District).
