The vast wetlands of Marshall County define this landscape, characterized by an extensive network of conservation areas and water management systems. Portions of Rollis, Eckvoll, and Moylan are dominated by the Agassiz National Wildlife Refuge, where the Mud River and Lost River meander through a series of pools and marshes. The map documents significant hydrological engineering, including the Upper CCC Pool and numerous judicial ditches designed to manage the flow through this low-lying prairie region.
