Agassiz National Wildlife Refuge dominates this northern Minnesota landscape, where extensive wetlands and brushy terrain are meticulously managed for migratory birds. The map illustrates a complex hydrologic network designed to control water flow across the low-lying plains of Moylan and Rollis, including the winding Mud River and Lost River. The intersection of natural watercourses and engineered features like Judicial Ditch No 11 and the Upper Pool at a normal pool elevation of 1143 feet reveals the 20th-century transition of this land toward conservation. Neighboring protection zones such as the Eckvoll State Wildlife Management Area and Elm Lake State Wildlife Management Area create a continuous corridor of protected habitat. Throughout Whiteford and Grand Plain, the scattered sections are largely undeveloped, save for occasional landmarks like a Gravel Pit, reflecting the area's remote character.
