The 18 square mile Mill Creek Watershed is fed by runoff that begins in the Hoover Wilderness at the 12,000-foot peaks above Lundy Canyon. The stream hosts rainbow trout.
Though Mill Creek is the only creek that wasn’t diverted into the Los Angeles Aqueduct, it is impacted by diversions for hydropower and irrigation, which have resulted in the degradation of the historical fishery and riparian habitat.
The stream is part of the Federal Energy Regulatory Commission (FERC) re-licensing process for the hydropower station at Lundy Lake. Working with partner groups/agencies and per a FERC re-licensing agreement, opportunities for restoration exist on Mill Creek, and thus water may be returned to it in the future.
