The U.S. Army Corps of Engineers' Upper Mississippi River Restoration (UMRR) program, through its Long Term Resource Monitoring (LTRM) element, collected aerial imagery of the systemic Upper Mississippi River System (UMRS) during the summer of 2020. A Land Cover/Land Use (LCU) spatial database was developed based on the 2020 aerial imagery, which adds a fourth systemic-wide database to the existing 1989, 2000, and 2010/11 LCU databases. These data have been used to create a variety of products, one of which is a data set used to classify aquatic areas. The 2020 aquatic areas data sets were created by first generalizing the available land cover/use data into a land/water data set, then reinterpreting the areas classified...

The Aquatic Area data sets were created by the Upper Midwest Environmental Sciences Center to identify areas of similar aquatic habitat, based primarily on large-scale geomorphic characteristics. These data are available as polygons and linears. The linear data set contains data for features too narrow to be mapped as polygons (e.g., wing dams, rip rap).
The Upper Midwest Environmental Sciences Center administers the US Army Corps of Engineers' Upper Mississippi River Restoration (UMRR) Program, Long Term Resource Monitoring (LTRM) element, authorized under the Water Resources Development Act of 1986 (Public Law 99-662). The mission of the UMRR-LTRM is to provide decision-makers with information to maintain the Upper Mississippi River System (UMRS) as a viable large river ecosystem given its multiple-use character. The long-term goals of the program are to understand the system, determine resource trends and impacts, develop management alternatives, manage information, and develop useful products. The creation and distribution of aquatic areas data for the UMRS...
