2020 Map of Priday Reservoir

About this map

Warner Valley defines the northeastern portion of this High Desert landscape, where the basin floor meets the steep ascent of Lynchs Rim. This 2020 survey documents a hydrologically sensitive environment where water sources are the primary landmarks. From Priday Reservoir in the north to the edge of Crump Lake in the south, the map is a ledger of essential water points including Ballew Lake and numerous named springs such as Finucane Spring and Antelope Spring. The distribution of these features, along with man-made improvements like the Sidewinder Waterhole and Lassie Waterhole, illustrates the region's historical and ongoing reliance on managed water for ranching. Transportation is sparse, confined largely to routes like Plush Adel Rd and Hogback Rd, which follow the natural contours between the valley floor and elevated plateaus like Monument Flat.
