2023 Map of Joes Valley Reservoir

About this map

Joes Valley Reservoir dominates this high-altitude landscape where the Wasatch Plateau transitions into the rugged drainage systems of Lower Joes Valley. Positioned within the Manti-La Sal National Forest, this 2023 survey illustrates the critical water infrastructure and recreational network of the Sanpete and Emery county border. The map details a complex system of mountain transit, from the engineered geometry of The Switchbacks on State Rte 29 to historical routes like Wagon Road Ridge. High-country water features such as Academy Mill Reservoir, Blue Lake, and Marys Lake are shown alongside prominent summits like Trail Mtn and North Horn Mtn, providing a modern view of a region defined by its timber, water, and grazing history.
