Pinnacles National Monument
Bear Gulch Reservoir is located above the Bear Gulch Caves (accessible along the Moses Spring Trail). The original dam predates the park, but recent modifications have been made, in part to control the impact of flooding downstream. The reservoir is located at the upstream end of Bear Gulch Cave, one of three talus caverns in Pinnacles National Monument (Rogers and others, 2003).
