USGS Topo · Published 2020About this map
Spring Valley is the primary settlement focal point in this portion of Valley County, situated at the confluence of several essential watercourses. The local hydrology is defined by the W Fork Little Porcupine Cr and the E Fork Little Porcupine Cr, which converge to form Little Porcupine Cr. This network of seasonal and perennial drainages has historically shaped the agricultural and ranching patterns of the region.
