Courtright Reservoir

Courtright Reservoir is a large body of water in the Sierra Nevada surrounded by granite formations and coniferous forest at over 8000 feet elevation. Built in the late 1950s with a dam standing over 300 feet tall, it stores water used for hydroelectric power generation through an innovative pumped storage system that moves water between two reservoirs based on electricity demand.

Built in the late 1950s to meet California's growing electricity demands, the reservoir transformed the mountain landscape when its dam was constructed. The pumped storage system that followed represented an innovative approach to power generation that helped balance electricity production across the region.

The reservoir serves as a gathering place for people seeking solitude and connection with the mountain landscape. Over time it has become a refuge where visitors can experience the quiet beauty of high elevation wilderness and appreciate how human infrastructure coexists with the natural environment.

The winding mountain roads to the reservoir require careful driving, especially during busy weekends or bad weather, so arriving early ensures parking availability. Be prepared for rapidly changing conditions at this high elevation by bringing proper gear and checking current road and weather information before your trip.

The power plant is hidden underground in solid granite roughly 1000 feet beneath the surface near Wishon Reservoir, with turbines that function in both directions as generators and pumps. This remarkable engineering allows water to flow downward for power generation and be pumped back up when electricity demand is low, creating a complete cycle of energy storage and production.
