2014 Map of Walls Lake

About this map

Walls Lake Reservoir and the adjacent Walls Lake anchor this high-desert landscape in Harney County, illustrating a complex hydraulic system in a terminal basin environment. The 2014 survey documents the drainage patterns through Walls Lake Canyon and south toward the expanse of the Catlow Valley. Notable geologic and topographic features like the Hole in the Ground and the La Voy Tables suggest a terrain shaped by ancient volcanic and erosional forces. A sparse network of primitive roads, including Jack Mountain Rd and Clover Swail Rd, provides the only access through this desolate rangeland. The map also records smaller water bodies such as Little Walls Lake and La Voy Lakes, which are critical landmarks for land management and local history in this arid corner of Oregon.
