Thief River winds through this low-lying wetland landscape in Marshall County, defined by the intricate water management systems of the Agassiz region. The map reveals a complex network of artificial and natural water bodies, including the Madsen Reservoir and Lansing Parker Reservoir, which serve as critical nodes in the local hydrology. This area is characterized by vast expanses of pools such as Agassiz Pool, Northwest Pool, and Thief Bay Pool, illustrating the transition of the Red River Valley’s eastern edge into managed marshlands. A rigid grid of section roads, including Co Hwy-7 and 300th St NE, provides access through the saturated terrain, connecting remote drainage points and water control structures like Green Stump Pool and Mud Lake.
