About this map

Walls Lake Reservoir and the seasonal catchment of Walls Lake anchor this high desert landscape within Catlow Valley. Surveyed in the early 1970s, the terrain is defined by dramatic topographic sinks and depressions, most notably the aptly named Hole In The Ground and the steep escarpments of the La Voy Tables. This arid environment necessitated a specialized infrastructure of water management, evidenced by several scattered Wells and Dry Wells used to sustain livestock across the scrubland.

Transportation is limited to a network of a Jeep Trail, illustrating the isolation of this corner of Harney County. The map provides clear evidence of land use through labeled resource extraction sites like a Borrow Pit and Gravel Pit, likely used for maintaining the remote access routes. These features, combined with the presence of La Voy Lakes and Little Walls Lake, offer a detailed look at the hydrology of a basin where water is a vital, seasonal commodity.
