Wisconsin Water Science Center

Data and Tools

The Wisconsin Water Science Center collects, analyzes, and distributes data on a wide variety of water-related issues and resources. Much of our data is publicly available through the USGS National Water Information System (NWIS), but additional datasets and analytical tools are also available.

Surface-water data for Wisconsin

Real-time, daily, peak-flow, field measurements, and statistics of current and historical data that describe stream levels, streamflow (discharge), reservoir and lake levels, surface-water quality, and rainfall in Wisconsin. Surface-water data are collected and stored as either discrete field-water-level measurements or as continuous time-series data from automated recorders.

Groundwater data for Wisconsin

Data from wells, springs, test holes, tunnels, drains, and excavations in Wisconsin; well location data includes information such as latitude and longitude, well depth, and aquifer. Groundwater level data are collected and stored as either discrete field-water-level measurements or as continuous time-series data from automated recorders.

Water-quality data for Wisconsin

Chemical, physical, and biological properties of water, sediment, and tissue samples from Wisconsin. Water-quality data are collected as either discrete field measurements or as continuous time-series data from automated recorders that continuously record physical and chemical characteristics including pH, specific conductance, temperature, and dissolved oxygen.

Water-use data for Wisconsin

Water-use data is collected by area type (state, county, watershed, or aquifer) and source (such as rivers or groundwater), and category (such as public supply or irrigation). Water-use data has been reported every five years since 1950. The USGS works in cooperation with local, State, and Federal agencies as well as academic and private organizations to collect and report withdrawals.

Lake-level data for Wisconsin

Real-time water levels and long-term statistics for lakes and reservoirs in Wisconsin. Lake data are collected and stored as continuous time-series data from automated recorders.

National Water Information System (NWIS) mapper

This mapper provides access to over 1.5 million sites contained in the USGS National Water Information System (NWIS), including sites where surface-water, groundwater, springs, and atmospheric data has been collected.

Annual Water Data reports

Annual Water Data Reports were published annually for many decades as static archival products that supplemented direct access to current and historical water data provided by the National Water Information System (NWIS). This site helps users access historical Water Data Reports, electronic Site Data Sheets, or current on-demand, print-ready Water-Year Summaries.

Water-quality and lake-stage data reports for Wisconsin lakes

The purpose of these reports is to provide information about the chemical and physical characteristics of Wisconsin lakes. Data that have been collected at specific lakes, and information to aid in the interpretation of those data, are included in these reports.

WaterWatch (surface water)

WaterWatch displays maps, graphs, and tables describing real-time, recent, and past streamflow conditions for the United States, including flood and droughts. Real-time information generally is updated on an hourly basis.

Groundwater Watch

Groundwater Watch displays maps, graphs, and tables describing real-time, recent, and historical groundwater data from wells and springs across the United States. Groundwater Watch groups related wells and data from active well networks and provides basic statistics about the water-level data collected by the USGS and from data supplied to us from partners through cooperative agreements.

WaterQualityWatch

WaterQualityWatch provides access to real time water-quality data collected in surface waters throughout the United States, including streamflow, water temperature, specific conductance, pH, dissolved oxygen, turbidity, and nitrate.

Water Quality Portal

The Water Quality Portal integrates and provides access to publicly available water-quality data from databases such as USGS NWIS and BioData, EPA STORET, and USDA-ARS STEWARDS through a single search interface.
