2024 Map of Garrison Lake

About this map

Catlow Valley defines the high-desert geography of this corner of Harney County, where water is the primary architect of the human and natural landscape. This modern digital survey reveals a complex system of managed water resources, including the engineered Stockwater Ditch that cuts across the basin to support livestock in this arid environment. Natural water bodies like Garrison Lake, West Field Lake, and Sixmile Lake appear alongside the Threemile Reservoir, illustrating the essential balance of ephemeral and permanent water sources in the Great Basin. The presence of Skull Creek and the lone artery of Catlow Valley Rd highlights the sparse infrastructure and remote character of the region. For the researcher, the map provides a precise layout of the Public Land Survey System, marking the intersections of Township and Range lines that have governed land use in this part of Oregon for generations.
