2011 Map of South Sandstone Reservoir

About this map

South Sandstone Reservoir sits at the heart of this Fallon County drainage basin, illustrating the critical role of water management in eastern Montana. The landscape is defined by the winding course of the South Fork Sandstone Creek, which feeds into the reservoir secured by the South Sandstone Creek Dam. The distribution of smaller impoundments, such as the R Maier Dam and Ehret Number 1 Dam, reflects the historical importance of local water storage for ranching and agriculture in this semi-arid region. Tributaries including Coon Creek, Pine Creek, and Timber Creek etch a complex network of coulees and draws across the terrain. A sparse network of rural routes, including Road 301, provides the primary access through this open country, highlighting the isolation and vast distances characteristic of the high plains.
