UPPER MISSOURI RIVER ENVIRONMENTAL MONITORING AND ASSESSMENT PROGRAM (EMAP-UMR) IN MONTANA AND NORTH AND SOUTH DAKOTA
Thompson, J A., T. Angradi, D W. Bolgrien, A. R. Carlson, J. R. Kelly, J. V. Scharold, AND E. W. Schweiger. UPPER MISSOURI RIVER ENVIRONMENTAL MONITORING AND ASSESSMENT PROGRAM (EMAP-UMR) IN MONTANA AND NORTH AND SOUTH DAKOTA. Presented at North American Benthological Society Annual Meeting, Keystone, CO, May 28-June 1, 2000.
In summer 2000, the EPA Office of Research Development's Mid-Continent Ecology Division, in cooperation with EPA Region 8 and States, will begin an EMAP effort on the aquatic resources of the UMR including the river, floodplain and mainstem reservoirs. The objective of this project is to contribute to the scientific underpinning for adaptive management of the UMR via improved ecological assessment and monitoring. Products will include recommended biological indicators, potential stressors, stressor-condition associations, delineation of important sources of variation, development of appropriate sample designs for assessments, and ultimately, an ecological assessment of the UMR. Sample sites will be located using the EMAP stratified random design which produces unbiased estimates of resource condition with known statistical confidence. In 2000, pilot studies will focus on the Garrison Reach of the UMR (ND) and Oahe Reservoir (ND and SD). Initial efforts will inlcude (1) a synoptic survey of water chemistry and sediment in t he mainstem and reservoir; (2) an assessment of the trophic status of Lake Oahe; (3) quantification of longitudinal and interhabitat variation in the riverine and reservoir macrobenthos; (4) analysis and classification of floodplain riparian condition, including the functional significance of woody debris in the mainstem; and (5) an evaluation of the use of multiple stable isotopes as indicators of ecological condition.
