2020 Map of Decker

About this map

The Tongue River and its expansive Tongue River Reservoir anchor this 2020 landscape in Big Horn County, defining the hydrology of a region where high plains meet broken breaks. The small settlement of Decker sits in the southwestern portion of the map, served by Decker Rd and Co RD 314. The terrain is deeply dissected by numerous drainages including Pearson Cr, Pond Cr, and Deer Cr, which feed into the central waterway. To the southeast, the Badger Hills rise above the drainage of Badger Cr, illustrating the complex topography typical of the Montana-Wyoming borderlands. The map also identifies several specific groundwater sources such as the 08S40E34ACCA01 Spring, providing a precise record of water resources critical to the local ranching and agricultural economy.
