Service Description: The objective of this work was to delineate areas in the Upper Mississippi River System where the combined effects of water clarity and water level fluctuation conditions are not limiting the establishment and persistence of submersed aquatic vegetation (SAV). We note that other factors, such as herbivory or high current velocity may actively prevent establishment of submersed aquatic vegetation in areas of the Upper Mississippi River System, and that this analysis is based on physical constraints imposed by water clarity and water level fluctuation only. Total suspended solids information was collected by the Upper Mississippi River Restoration program, and water level information was collected by the United State Army Corps of Engineers and United States Geological Survey and water depth data from the USGS to map areas suitable for support of submersed aquatic vegetation using four scenarios (lower SAV boundary elevation, lower SAV boundary elevation -1 SD, lower SAV boundary elevation + 1 SD, lower SAV boundary elevation with a 75% reduction in total suspended solids) https://www.usgs.gov/centers/umesc/science/understanding-constraints-submersed-vegetation-distribution-a-large-floodplain
