2014 Map of Rex Reservoir

About this map

Fishlake National Forest defines the high-altitude terrain of Sevier County, where a network of forest roads and springs supports the region's high-country livestock and recreation. The landscape is marked by a series of open flats such as Hearthstone Flat, Zero Flat, and Pinenuts Flat, illustrating the transition between wooded slopes and high meadows. At the heart of the drainage system lies Rex Reservoir, fed by Lost Cr, which serves as a critical water source in this arid mountain environment. Evidence of historical land use appears in named landmarks like Scorups Meadows and the curiously named Purgatory and Hock Swale. The map traces numerous springs, including Kinnikinnick Spring and Hearthstone Spring, which were vital for early settlement and ranching efforts in these high basins before modern water management.
