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).

The Long Term Resource Monitoring (LTRM) element is one of two components of the federally mandated Upper Mississippi River Restoration (UMRR) Program, a cooperative program between the U.S. Army Corps of Engineers, U.S. Geological Survey, U.S. Fish and Wildlife Service, U.S. Environmental Protection Agency, and the states of Illinois, Iowa, Minnesota, Missouri, and Wisconsin. Data release products listed below are associated with the analysis of LTRM data and LTRM staff publications.

Wind fetch is defined as the unobstructed distance that wind can travel over water in a constant direction. Fetch is an important characteristic of open water because longer fetch can result in larger wind-generated waves. The larger waves, in turn, can increase shoreline erosion and sediment re-suspension. A baseline conditions assessment of wind fetch was conducted to assist the Upper Mississippi River Restoration program's Long Term Resource Monitoring element (LTRM) in identifying areas within the river system where excessive wind fetch could be a problem. This was accomplished using three separate years of land cover/land use data developed by the LTRM (1989, 2000, and 2010/2011). Wind fetch from 36 directions...
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.

The LTRMP samples probabilistically using a stratified random sampling design within five reaches of the Upper Mississippi River (UMR) and one reach of the Illinois River. These six reaches represent a judgment sample of reaches within the Upper Mississippi River System (UMRS), and, as a result, inferences about either the UMR or the UMRS from LTRMP data must rely on models rather than on the design.
