The Long Term Resource Monitoring Program (LTRMP), a component of the Environmental Management Program for the Upper Mississippi River System (UMRS), is funded by the U.S. Army Corps of Engineers and administered by the U.S. Geological Survey's Upper Midwest Environmental Sciences Center (Center) 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...

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. Information on important ecosystem components, including water quality, fish, vegetation, and macroinvertebrates are obtained annually using standardized procedures. Other data such as land cover/land use and bathymetry are gathered and analyzed periodically. Monitoring activities...

Floodplain rivers have been conceptualized as patchwork mosaics of hydrogeomorphic zones that differ in hydrological, physiochemical, and ecological conditions. However, few investigators have empirically examined the extent to which basic ecological properties of large rivers, such as nutrient concentrations, are patchily distributed or the relationship between such distributions and water-mediated connectivity. We used global and local measures of spatial autocorrelation in 5 reaches of the Upper Mississippi River from 1994–2008 in spring (higher discharge) and summer (lower discharge) to examine distributions of total N (TN), total P (TP), and TNTP for evidence of patchiness. TN was distributed as discrete patches...

This report presents a broad overview of spatial and temporal variation in the water quality of the Upper Mississippi River System (UMRS). The Long Term Resource Monitoring Program (LTRMP) provides a systemic perspective through the collection and analysis of monitoring data from six study reaches representing the upper, lower, and open river reaches of the UMRS (Upper Mississippi River: Pools 4, 8, 13, and 26, Open River [near Cape Girardeau, Missouri]; Illinois River: La Grange Pool). This report presents data from 1993 to 2001 (or 2002 when available) and focuses on spring and summer conditions. Water quality constituents (e.g., turbidity, suspended solids, chlorophyll, nutrients, and dissolved oxygen) varied...
