About this map

Sanchez Reservoir dominates this high-altitude landscape in Costilla County, situated within the expansive Mesa De San Pedro Grant. This 1967 field-checked study illustrates a complex drainage network feeding into the reservoir, including Ventero Creek, Torcido Creek, and Jaroso Creek. The map provides a detailed look at the water infrastructure of the era, specifically noting the Spillway Elev 8217 at the northern end of the basin.

Evidence of local resource extraction and early land navigation is scattered throughout the terrain, including several Gravel Pits and a noted Prospect in the southwestern corner. A series of Jeep Trails wind through the mesa, connecting the various creek valleys such as Cuates Creek and Willow Jarocito Cr. The map captures a moment in the late 1960s when the land was defined by a mix of historic land grants and modern irrigation management.
