1967 Map of Willow Park Reservoir

About this map

Bighorn National Forest serves as the backdrop for this high-altitude hydrological study in Johnson County, Wyoming. The landscape is defined by its complex drainage network, where North Piney Creek and South Piney Creek navigate a terrain of glacial lakes and managed water systems. Significant mountain water storage is documented at Cloud Peak Reservoir, Willow Park Reservoir, and Kearny Lake Res, illustrating the importance of high-country runoff to regional water management in the late 1960s.
