2012 Map of Willow Park Reservoir

About this map

Willow Park Reservoir and its surrounding alpine basin define this high-altitude landscape in the Bighorn Mountains. The 2012 survey illustrates a complex hydrologic network managed for water storage and diversion, notably featuring the Rock Creek and Piney Diversion Ditch cutting across the northeastern terrain. Small mountain lakes are scattered throughout the region, including named basins such as Frying Pan Lake, Gem Lake, and the remote Lake Mead. Human activity is primarily centered around seasonal grazing and water management, evidenced by the presence of Hepp Cow Camp near the reservoir. Drainage patterns are dominated by the forks of S Piney Cr, N Piney Cr, and Kearny Cr, which feed into major impoundments like Kearny Lake Reservoir and the Cloud Peak Reservoir. This map serves as a precise record of these vital watersheds and their associated infrastructure in the early 21st century.
