2021 Map of Park Reservoir

About this map

Bighorn National Forest contains a complex network of water management features and high-altitude parks along the Sheridan and Johnson County line. Central to this landscape is the namesake Park Reservoir, surrounded by smaller impoundments like Martin Reservoir, Willits Reservoir, and Last Chance Reservoir. The integration of man-made irrigation infrastructure, such as the Big Goose and Beaver Ditch and the Peralta Ditch, reflects the critical role of water diversion in this mountainous region. Settlement is absent here, replaced by a dense system of pack trails and access routes including the Bishop Mine Trl and the Big Goose Cutoff Trl. Named meadows and rock formations like Big Goose Park, Finger Rock, and Lamburger Rock provide specific landmarks for locating historic summer grazing sites or early mining prospects.
