Hell Hole Reservoir

Hell Hole Reservoir is a water storage lake in California located in a mountainous area that supplies the region. The lake features steep shorelines and deep waters surrounded by dense forests and rocky outcroppings.

The reservoir was built in the mid-20th century to store water for power generation and irrigation purposes. Its construction was part of a broader water management project in the Sierra Nevada region.

The lake is reached via forest service roads and best visited during warmer months when access routes are passable. Visitors should prepare for uneven terrain and remote conditions.

The lake's name comes from a natural rocky hole discovered during dam construction that posed a geological challenge. This discovery led to unexpected engineering solutions during the building phase.
