Stream Water Quality

The Kalamazoo River, a federal Superfund site, contains sediments contaminated with PCBs from historical paper mills. Dam control and erosion has exposed and mobilized the contaminated sediment, transporting and depositing it downstream. This study determined the historical geomorphic changes, measured bank stability, and evaluated the potential effects of future dam failure and removal scenarios.

Little St. Germain Lake, Wis., consists of four main basins separated by narrows. This study monitored lake water quality, identified phosphorus sources, determined spatial and temporal distribution of oxygen, evaluated the effectiveness of winter aeration systems, and modeled groundwater/lake-water interactions.

North Fish Creek, Wisconsin, has accelerated erosion and sedimentation that negatively affects aquatic habitat. This project monitored three rehabilitation projects (including submerged flow-deflecting vanes) to determine their effect on bluff erosion rates and sediment volumes, and to describe the upland land cover and soils. This data will help guide runoff management and bluff restoration...

Riparian grazing allows cattle free access to streams, but may accelerate erosion by the removal or trampling of vegetation. This study measured stream bank erosion, channel morphology, and stream substrate through seven experimental intensive-rotational pastures. It also evaluated the use of photo-electronic erosion pins (PEEPs) for measuring bank erosion in this type of geomorphic setting.

Lake Superior tributaries in Bayfield County, Wis., have accelerated erosion and sedimentation influenced by changing land use, steep slopes, erodible soils, and flashy runoff. This project assessed the geomorpology of five tributaries, identified problem areas, and assessed rehabilitation alternatives and watershed management strategies specifically related to the rehabilitation of brook trout.

The USGS and Wisconsin DNR collected water-quality and biological data from 240 wadeable streams and 40 nonwadeable rivers throughout Wisconsin to evaluate the potential environmental benefits of enforcing nutrient criteria and standards for streams and rivers if they better reflected regionally defined, scientifically defensible thresholds to biotic response.

The U.S. Geological Survey (USGS) Michigan Bacteriological Research Laboratory (MI-BaRL) conducts ecological studies on the structure and function of eubacterial and archeal communities in the environment. Studies of this type give us basic information about the composition and functionality of different microbial communities and allow us to investigate the effects that natural and anthropogenic...

The USGS implemented the National Water-Quality Assessment (NAWQA) Program in 1991 to develop long-term consistent and comparable information on streams, rivers, groundwater, and aquatic systems in support of national, regional, State, and local information needs and decisions related to water-quality management and policy.

As part of the USGS National Water Quality Assessment (NAWQA) program the USGS MIWSC operates a stream gage and routinely collects water quality samples at the Clinton River at Sterling Heights, MI. station. Water is analyzed for sediment, nutrients, major ions, and a suite of 271 different pesticides. Information obtained from this site is compiled with information from other National Fixed...

The U.S. Geological Survey (USGS) Michigan Bacteriological Research Laboratory (MI-BaRL) is a newly renovated laboratory space operated by the USGS Michigan Water Science Center in Lansing, MI. The laboratory is staffed by two Ph.D. level microbiologists and five M.S. level microbiologists with a combined 70 years of experience in microbiology and water resources research. The USGS MI-BaRL...

Microbiologists at the Michigan Bacteriological Research Laboratory (MI-BaRL) use a wide array of traditional and modern molecular approaches to evaluate microbial pathogens and antimicrobial resistance pathways in the environment.
