Impact of phosphorus and nitrogen concentrations on the biological integrity of Wisconsin streams
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.
Water use in Wisconsin
Water-use information is essential for managing Wisconsin's valuable water resources. This critical information includes knowing how much, where, and for what purpose water is being used. The USGS works in cooperation with local, state, and federal environmental agencies to collect water-use information, and compiles and disseminates aggregated data at the county, state, and national level.
Streamflow monitoring in Wisconsin
Streamflow data are needed at many sites on a daily basis for forecasting flow conditions and flooding, water-management decisions, assessing water availability, managing water quality, and meeting legal requirements. The USGS has been measuring streamflow in Wisconsin since 1906 with nearly 1,000 active and discontinued gages.
Flood hazards in Wisconsin
A summary of USGS resources and data related to flooding hazards in Wisconsin.
Drought hazards in Wisconsin
A summary of USGS resources and data related to drought hazards in Wisconsin.
Flood frequency in Wisconsin
Flood-frequency estimates are required at many sites for bridge and culvert design, as well as for flood-plain management and flood-insurance studies. To estimate flood frequency at ungaged locations, a network of approximately 90 crest-stage gages and more than 200 past and current continuous-record gages are used to compute regional flood-frequency equations to estimate floods at ungaged sites.
June 2008 floods in southern Wisconsin
In June 2008, heavy rain caused severe flooding across southern Wisconsin. Record gage heights and streamflows occurred at 21 U.S. Geological Survey streamgages across southern Wisconsin from June 7 to June 21.
Water, Energy, and Biogeochemical Budgets (WEBB): Trout Lake
USGS initiated the Water, Energy, and Biogeochemical Budgets (WEBB) program to understand the processes controlling water, energy, and biogeochemical fluxes over a range of temporal and spatial scales, and the effects of atmospheric and climatic variables. Trout Lake is one of five small, geographically and ecologically diverse watersheds representing a range of hydrologic and climatic conditions.
Evaluating the risks of airborne pathogens from manure irrigation
Manure irrigation, which is the application of liquid animal manure by irrigation, is increasing. However, the risk of airborne pathogen transmission from manure to humans during spray irrigation is not well-understood. To determine how pathogens can spread using manure irrigation, LIDE measured air concentrations and risk of illness due to exposure to pathogens in the irrigation spray.
