Spatial, temporal, and environmental trends of fish assemblages within six reaches of the Upper Mississippi River System We investigated differences in adult and young-of-the-year (YOY) fishes within each of the six Long Term Resource Monitoring Program study areas, using monitoring data from 1993 to 2001. Our objective was to investigate the relative roles of seasonal, annual, in situ, and physical habitat factors in explaining assemblage structure patterns within the Long Term Resource Monitoring Program study areas. Adult and YOY assemblage structure within each reach was dominated by one to three numerically abundant species. The percent of the total abundance for which these species accounted was 10–88% and varied among age classes and study areas. Physical habitat classes were only weakly associated with differences in fish... Categories: Publication; Types: Map Service, OGC WFS Layer, OGC WMS Layer, OGC WMS Service

Summary of monitoring findings for Fiscal Year 2001 Long Term Resource Monitoring Program of the Upper Mississippi River System The Long Term Resource Monitoring Program (LTRMP), a component of the Environmental Management Program for the Upper Mississippi River System, is administered by the U.S. Geological Survey's Upper Midwest Environmental Sciences Center (UMESC) in La Crosse, Wisconsin. The LTRMP supports six field stations operated by state agencies in Illinois, Iowa, Minnesota, Missouri, and Wisconsin ( Figure 1) to collect most of the monitoring data. Data on important ecosystem components, including water quality, vegetation, macroinvertebrates, and fish, are obtained using standardized operating procedures. Monitoring activities focus primarily on six study areas: Navigation Pools 4, 8, 13, and 26 and Open River on the Mississippi...
