2023 Map of Ross Lake

USGS Topo · Published 2023

About this map

Ross Lake and its surrounding high-desert wetlands define this corner of Owyhee County, where a complex network of seasonal water and irrigation infrastructure has been carefully mapped. The landscape is marked by the distinct drainage of Yatahoney Creek and the meandering Ross Slough, which feeds into several significant basins. This 2023 survey details the vital water management features of the area, including Yatahoney Reservoir Number 1, Yatahoney Reservoir Number 2, and Millin Reservoir. Significant terrain features like Mud Flat and Pleasant Valley illustrate the varied topography of this remote region. For those tracking land use and hydrology, the presence of Juniper Lake, Henry Lake, and Willies Reservoir alongside the 903 Bia route provides a clear picture of the modern interface between natural water bodies and managed resources in this part of Idaho.
