The Sacagawea River winds through this Fergus County landscape, defining the local drainage patterns that include Dexter Coulee and Griffee Coulee. This 2011 survey reveals a region heavily modified for water management in an otherwise arid environment, evidenced by multiple small-scale infrastructure projects such as Cimrhakle Number 2 Dam, Cimrhakle Number 3 Dam, and Lazy JD Number 10 Dam. These features, often associated with private ranching operations, illustrate the critical importance of water storage in the high plains.
