The Middle Fork Project includes five developments:  French Meadows, Hell Hole, Middle Fork, Ralston, and Oxbow and is located in Placer and El Dorado counties, almost entirely within theTahoe and El Dorado National Forests. The Project serves as both a water supply and a hydroelectric project.

The project is operated in a seasonal store and release mode.  Typical annual operation of the project results in the capture of runoff, which is diverted to increase storage in the French Meadows and Hell Hole reservoirs during the winter and spring.  Reservoir storage is later released during the summer, fall, and early winter.  Storage and release of flows varies from year to year based on the timing and magnitude of spring runoff, which is influenced by winter snow pack, temperature conditions, and precipitation.
