2017 Map of Walls Lake

About this map

Walls Lake Reservoir and the adjacent Walls Lake anchor this high-desert landscape in Harney County. The terrain is defined by dramatic depressions and basaltic features, most notably the circular Hole-in-the-Ground and the steep descents of Walls Lake Canyon. These natural catchments provided critical water sources for the cattle ranching operations that have long defined the region's economy. Movement through the area is dictated by the landform, with Jack Mountain Rd and Walls Lake Rd following the natural contours between the basin and the La Voy Tables. To the south, the map captures the transition into the expansive Catlow Valley, where a network of unpaved tracks like Rock Creek Ln and Clover Swail Rd connect isolated waterholes and range land. The presence of La Voy Lakes further illustrates the importance of ephemeral water in this arid interior.
