Landform characteristics dictate water movement, water storage, and water retention. The Prairie Pothole Region (PPR) is characterized by numerous catchment basins that provide water retention, wildlife habitat, and water quality functions. Understanding how water moves across PPR landforms within and among watersheds is needed for functional assessment of PPR agricultural wetland landscapes.
New watershed data are now available for the central North Dakota PPR, located between Bismarck and Minot along the Missouri Coteau.
Landform topographic features indicate where surface waters potentially flow and eventually drain to major rivers. For our area-of-interest, there are three major river outlets:the Missouri, the Souris, and the Sheyenne. These drainage points can be used to model the area contributing water to each point—this area is defined as the watershed. Within each watershed are thousands of drainage networks and catchments basins that are used to characterize water movement, storage and retention. A topographic map detailing the elevation of the area is shown below and it also displays the outlets for all the subwatershed mapped.
