2010 Map of Sinker Canyon

About this map

Diamond Basin and the winding course of Sinker Creek anchor this high-desert Owyhee County landscape at the start of the 21st century. The map illustrates a watershed defined by complex drainage systems, including the numerous branches of Fossil Creek and Bates Creek that cut through the basin. Agricultural and ranching infrastructure is central to the area's layout, marked by the presence of Gilmore Ranch and Spring Ranch. Managed water resources are prominently featured, specifically Hulet Dam which creates the Hulet-Sinker Creek Reservoir. Transportation through this remote terrain is facilitated by several major thoroughfares, such as Silver City Rd and Sinker Creek Rd, which provide access to the deep topography of Sinker Canyon and the engineered routes of the Murphy Mutual Canal.
