2011 Map of Big Flat East

About this map

Big Flat characterizes the wide, open landscape of Phillips County in this 2011 survey, a region defined by its critical water management infrastructure and drainage patterns. The northern section is anchored by Weigand Reservoir and the headwaters of Mud Creek, while Wild Horse Creek winds through the southern portion of the quadrangle. Significant water control features include the JFK Dam and Ernest Dam, which serve this agricultural and grazing territory. The terrain is further marked by distinct erosional features such as Chicken Coulee and Rocky Coulee, which cut through the high plains. Infrastructure is sparse, primarily consisting of Hwy-204 and various local routes providing access across the expansive Montana landscape.
