2017 Map of Southwest Harney Lake

About this map

Harney Lake and the arid terrain of Warm Springs Valley dominate this corner of the High Desert. The landscape is defined by its water sources, including the strategically placed Basco Spring Reservoir and several named springs like Soldier Spring and Bathtub Spring that provided critical hydration for range livestock and travelers. The presence of Basque Flat points to the regional history of sheep ranching, while the remote tracks of S Harney Rd and S Harney Lake Rd follow the contours of the basin. Topographic details show the stark transition from the lake bed to the surrounding flats, such as Weed Lake Flat, and minor drainage points like Hughes Cr. This survey documents a vital part of the county's hydraulic infrastructure, from the Weed Lake Butte Waterhole to the Upper Sizemore Spring.
