About this map

Arrowwood National Wildlife Refuge dominates this section of the Jim River Valley, protecting a vast chain of wetlands along the James River. During the early 1990s, this landscape remained a critical corridor for migratory birds, characterized by the expansive waters of Jim Lake and the marshy reaches of Mud Lake. The topography is defined by the glacial legacy of the Grasshopper Hills, which rise above the river bottomlands to the east.

The map details the intersection of conservation and agriculture, showing the proximity of the National Waterfowl Production Area to the rural boundaries of Edmunds, Kensal, and Lyon. Smaller isolated water bodies such as Medicine Lake and Plowe Lake dot the surrounding prairie, illustrating the complex hydrology of the North Dakota pothole region before later 20th-century climate and land-use shifts further altered these drainage patterns.
