1968 Map of Harrence Lake

About this map

Hydrological management defines this high-elevation landscape in Saguache County, where a complex system of flowing wells and arroyos supports the local ecosystem. The map reveals the intricate water network of the Russell Lakes region, including Harrence Lake, Davey Lake, and Island Lake. A Fish Hatchery located near the western margin suggests the importance of wildlife and aquatic resource management in the late 1960s. The terrain is characterized by its drainage patterns, with Werner Arroyo and Bull Arroyo feeding into larger systems like Russell Creek and La Garita Creek. Numerous Flowing Wells are plotted across the township and range lines, indicating the subsurface water reliance that sustained this portion of the San Luis Valley during the mid-20th century.
