Multiyear Synthesis of Limnological Data from 1993 to 2001 for the Long Term Resource Monitoring Program
Abstract
This report presents a broad overview of spatial and temporal variation in the limnological characteristics of the Upper Mississippi River System (UMRS). Important sources of variability within the UMRS include a longitudinal (north-south) gradient, and differences among years, seasons, and aquatic areas (e.g., main channel versus contiguous backwaters). Understanding spatial and temporal variation at these scales requires a systemic perspective on the river. 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: Pool 4 near Lake City, Minnesota; Pool 8 near Onalaska, Wisconsin; Pool 13 near Bellevue, Iowa; Pool 26 near Alton, Illinois; Open River, near Cape Girardeau, Missouri; and La Orange Pool of the Illinois River near Havana, Illinois. This report presents data from 1993 to 2001 (or 2002 when available). The focus is on spring and summer conditions because spring is the time of maximum discharge and, therefore, maximum transport of suspended solids and nutrients and summer is the time of peak biological activity. Winter data are included in the analyses of dissolved oxygen because dissolved oxygen may be a critical component of winter habitat for many fish species within the northern reaches of the UMRS.
