The Bad River has one of the highest sediment loads of all Lake Superior tributaries and is an important resource for lake sturgeon and the Bad River Tribe. This study monitors the effects of streamflow variability on sediment-related problems, including understanding the influence of land cover on hydrology, habitat, erosion and sedimentation rates, and water quality of the Bad River.

Chemicals used to deice planes at General Mitchell International Airport in Milwaukee may be entering nearby streams in concentrations that may be harmful to aquatic life. This project will investigate the toxicity of decing chemicals, evaluate their impact on receiving streams, and assess changes in water quality in response to the implementation of deicer management at General Mitchell Airport.

Since 2000, the USGS and MMSD have been partners in the Milwaukee Area Watercourse Corridor Study. The USGS has applied a multi-disciplinary approach to monitor and assess stream water quality within studies of aquatic communities, geomorphology and habitat, water and sediment, and streamflow. Results are provided to MMSD and watershed management agencies for planning and decision-making.

The MMSD Watercourse Corridor Study supports seven USGS streamflow gages on Milwaukee-area streams that measure real-time discharge and gage height; five of these sites also collect time-lapse videos.

The effectiveness of green infrastructure (including urban land conversion and bioswales) at reducing stormwater runoff is being assessed at RecoveryPark, a redeveloped urban farm in Detroit, Michigan. This study will monitor pre- and post-construction storm-sewer flow, groundwater levels, precipitation, and potential evapotranspiration (ET) to evaluate stormwater-volume reduction in response to...

The effectiveness of green infrastructure (rain gardens and decreased impervious surface) at reducing stormwater runoff and capturing dissolved chloride is being assessed at a redevelopment project at Gary City Hall (Gary, Indiana). This study will evaluate pre- and post-construction hydrologic conditions using data collected by monitoring storm-sewer flow, groundwater levels, soil moisture, and...

Much has been learned about how effectively individual green infrastructure practices can reduce stormwater volume, however, the role of urban trees in stormwater detention is poorly understood. This study quantified the impact that trees have on stormwater runoff volume.

The GLRI Urban Stormwater Monitoring effort brings together the expertise of the USGS with local and national partners to assess the ability of green infrastructure to reduce stormwater runoff in Great Lakes urban areas.

The Minnesota Pollution Control Agency (MPCA) lists streamflow alteration as a key stressor on aquatic life in many watersheds. However, the MPCA currently does not have the information needed to quantitatively associate metrics from Index of Biological Integrity (IBI) surveys with metrics of streamflow alteration. We are using USGS streamgage data and MPCA IBI data to develop relations between...

Fluvial geomorphology studies provide an understanding of the physical processes responsible for shaping the character of streams and their riparian zones across both glaciatied and unglaciated regions of Wisconsin and the midwestern U.S.

The USGS in Michigan-in cooperation with local, State, Tribal, and Federal partners-operates 155 streamgages recording stage and streamflow, and 13 lake-level gages. There are about 7,400 streamgages nationwide; many of these gages provide real-time data in 15-minute increments, which typically are transmitted to the World Wide Web every 1 to 2 hours using satellite, telephone, or cellular phone...

The U.S. Geological Survey is assessing the effectiveness of green infrastructure at attenuating and reducing stormflow along a 2.26 mile corridor of Niagara Street in Buffalo, NY. This research is being conducted in collaboration with the Environmental Protection Agency, the Buffalo Sewer Authority and University at Buffalo.
