UMRR Long Term Resource Monitoring


The LTRM element is one of two components of the federally mandated Upper Mississippi River Restoration 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.
