Annual Work Plan for the UMRS LTRMP, Fiscal Year 1993 U.S. Fish and Wildlife Service. 1992. Annual Work Plan for the Upper Mississippi River System Long Term Resource Monitoring Program, Fiscal Year 1993. Environmental Management Technical Center, Onalaska, Wisconsin, October 1992. EMTC 92-P001. 65 pp. (NTIS #PB94-112141) ABSTRACT The mission of the Long Term Resource Monitoring Program (LTRMP) is to provide decision makers with information needed to maintain the Upper Mississippi River System (UMRS) as a viable large river ecosystem given its multiple-use character. Congress has declared the System to be both a nationally significant ecosystem and a commercial navigation system. The long term goals of the Program are to (1) understand the UMRS ecosystem, (2) monitor trends and impacts with respect to selected resources, (3) develop resource management alternatives, (4) manage information, and (5) develop useful products. The LTRMP was authorized under the Water Resources Development Act of 1986 (Public Law 99-662) as an element of the U.S. Army Corps of Engineers' Environmental Management Program. The original authorization provided for a 10-year program (1987-1997). Authorization was subsequently extended 5 years (to 2002) by Section 405 of the Water Resources Act of 1990 (Public Law 101-640). This Annual Work Plan for the LTRMP for 1993 has been prepared for the U.S. Army Corps of Engineers (Corps) by the U.S. Fish and Wildlife Service, Environmental Management Technical Center (EMTC). This Plan allows the Corps, the Service, and Program participants to agree at the beginning of the fiscal year on work to be accomplished. It also facilitates the transfer of funds from the Corps' Environmental Management Program budget to the Service.
