The Long Term Resource Monitoring Program (LTRMP) of the Upper Mississippi River System (UMRS) was authorized under the Water Resources Development Act of 1986 (Public Law 99-662). The UMRS is composed of the navigable reaches of the Upper Mississippi, Illinois, Kaskaskia, Black, St. Croix and Minnesota rivers. Program objectives are: to analyze significant resource problems such as sedimentation, water level management, and navigation impacts; to monitor selected habitats and species; and to develop data management systems and techniques which will assist resource personnel to better manage the rivers' ecosystems.
