2022 Map of Vallecito Reservoir

About this map

Vallecito Reservoir dominates this portion of the San Juan National Forest, serving as a central catchment for the Los Pinos River and numerous high-country tributaries. The settlement of Vallecito sits at the southern edge of the water, where Cty Rd 501 provides access to the western shoreline. The landscape is characterized by high, flat-topped mesas and parks, including Endlich Mesa and Runlett Park, which are accessible via an extensive network of specialized paths like the Endlich Mesa Trl and Vallecito Horse Route 1. The drainage patterns here are intricate, with narrow canyons such as Dark Canyon and Blind Canyon cutting through the terrain. This map captures the modern recreational and water-management footprint of the region, illustrating how timber and water resources continue to shape the geography of the southwestern Colorado high country.
