About this map

The Columbia Road Reservoir dominates the southeastern portion of this landscape in Brown County, where the James River valley meets the agricultural grid of the Dakota prairies. This 2021 survey illustrates a transition from the marshy, wetland-rich basins characteristic of the James River floodplain to the high-plains agriculture of northern South Dakota. The presence of the Auto Tour Rte and N Tour Rte suggests a managed landscape designed for public access and wildlife observation, centered around the reservoir's waters. Inland, the map detail focuses on the township and range system, punctuated by landmarks like Comstock Field and a dense network of section-line roads, including Co Rd 7 and Co Rd 16. The terrain is defined by subtle elevation changes and numerous depressions, reflecting the glacial history of the region and its contemporary use for waterfowl habitat and cereal farming.
