The Upper Midwest Water Science Center collects, analyzes, and distributes data on a variety of water-related issues and resources. Much of our data is publicly available through the USGS National Water Information System (NWIS):

Surface water:  MI • MN • WI
Groundwater:  MI • MN • WI
Water quality:  MI • MN • WI

Water use:  MI • MN • WI

NWIS site inventory:  MI • MN • WI

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.

Wisconsin Real-Time Groundwater-Level Network

The Real-Time Groundwater Level Network contains data typically recorded at 15-60 minute intervals, stored onsite, and then transmitted to USGS offices every 1 to 4 hours, depending on the data relay technique used. Recording and transmission times may be more frequent during critical events. All real-time data are provisional and subject to revision.
