2011 Map of Chelsea NW

About this map

Chelsea Creek and Tule Creek define the drainage patterns across this section of Roosevelt County within the Wolf Point District. The landscape is marked by small-scale water management features typical of the Montana plains, including the Anderson Reservoir Number 1 Dam and the L Sayer-Magdelena Dam. These structures suggest a focus on water retention for livestock or local agricultural needs in an otherwise arid environment. The presence of the Tule Creek Bridge indicates a primary crossing point for the local road network, which follows a rigid section-line grid across the territory. This 2011 survey by the U.S. Geological Survey provides a precise view of the rural infrastructure and hydraulic engineering required to manage the area's intermittent water sources.
