The Finger Lakes Habitat Rehabilitation and Enhancement Project(HREP) is intended to improve winter habitat conditions for fish in a series of interconnected backwater lakes of the Mississippi River near Alma, Wisconsin. Winter habitat requirements (temperature, flow velocity, and dissolved oxygen) for the target fish population in the Finger Lakes have been defined and limnologcal efforts have been aimed at quantifying the spatial-temporal patterns and interrelationships among water movement, oxygen, and temperature. The progress to date (pre-construction) has included detailed investigations into (1) system hydrology (including dye-tracer studies), (2) oxygen supply and depletion, (3) temperature regime, (4) aquatic...

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...

The objective of this review was to evaluate the ability of existing models and modeling approaches to explain and predict temporal changes in fish abundance in the Upper Mississippi River System (UMRS) based on environmental factors. Information on models was obtained through a literature review and personal contacts with Federal and academic specialists. Models were evaluated based on their assumptions, data requirements, outputs generated, and applicability to UMRS fishes. Many existing models can incorporate environmental effects on fish populations, but none were developed specifically for large rivers. The models reviewed were of three types: analytical, empirical, and mechanistic. Of these three model types,...

This report summarizes monitoring activities of the Long Term Resource Monitoring Program (LTRMP) during 1999 and highlights selected results and accomplishments pertaining to hydrology, water quality, fish, macroinvertebrates, and vegetation. Mean discharge in 1999 was above average in the Upper Mississippi and Illinois Rivers, but spring flooding was relatively minor. Total nitrogen concentration has declined in the upper reaches of the LTRMP study area (Pools 4 and 8) from highs of about 4 mg/L in 1993 to present levels of about 1.5 mg/L. Mass balance budgets indicate that little nitrogen is lost (denitrified) as water moves through the LTRMP study pools on the Mississippi River. La Grange Pool on the Illinois...
