The approximate width of the Souris River floodplain varies throughout its course, but it generally ranges from half a mile to a few miles wide. Factors such as local topography, sediment deposition, and flood events can influence this width.
The floodplain is shaped by the river’s flow and can change with seasonal flooding or drought periods. In areas with significant agricultural development or urbanization, portions of the floodplain may have been altered to accommodate land uses, potentially affecting its overall size.
Understanding the dimensions of the floodplain is crucial for managing water resources, flood risks, and ecological health in the region. Properly delineating floodplain areas helps in planning and mitigating the impacts of flood hazards on communities and the environment.
