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.

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.

National Water Information System (NWIS) Mapper

The NWIS mapper provides access to over 1.5 million sites contained in the USGS National Water Information System (NWIS), including sites where current and historical surface-water, groundwater, springs, and atmospheric data has been collected. Users can search by site type, data type, site number, or place.

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.

National Ground-Water Monitoring Network (NGWMN) Data Portal

The NGWMN Data Portal provides access to groundwater data from multiple, dispersed databases in a web-based mapping application. The Portal contains current and historical data including water levels, water quality, lithology, and well construction.

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.

GLM model data sets used to evaluate changes in the hydrodynamics of Anvil Lake, Wisconsin: U.S. Geological Survey Data Release

Interannual differences in the water quality of Anvil Lake, WI, were examined to determine how water level and climate affect the hydrodynamics and trophic state of shallow lakes, and their importance compared to anthropogenic changes in the watershed. To determine how changes in water level may affect these processes, the General Lake Model (GLM) was used to simulate how the lake’s...

Eutrophication water-quality models and supporting water-quality and phosphorus load data used to simulate changes in the water quality of the Winnebago Pool Lakes, Wisconsin, in response to change in phosphorus loading

Three eutrophication models (mass balance, BATHUB, and Jensen models) were developed and calibrated for the Winnebago Pools, Wisconsin. These models were used to quantify the input of phosphorus from the sediments of the lakes, and determine how the water quality (total phosphorus concentration, chlorophyll a concentrations, and Secchi depth) should respond to changes in phosphorus loading...

Estimated daily loads of nutrients, sediment, and chloride at USGS edge-of-field stations, in Wisconsin, water years 2012-17

As part of the Great Lakes Restoration Initiative, the U.S. Department of Agriculture, Natural Resources Conservation Service; U.S. Environmental Protection Agency; and the U.S. Geological Survey (USGS) have partnered to evaluate agricultural conservation practices focused on nutrient management. Monitoring methods allow for rapid assessment of water-quality changes in response to conservation...

Regression models and associated data for describing variability of host specific bacteria fluxes in eight Great Lakes tributaries, 2011-2013

Three regression models were developed for describing variability of host-specific flux data in eight Great Lakes tributaries. Models include one for Lachnospiraceae flux, one for human bacteroides flux, and one for ruminant bacteroides flux. Models were developed using the R project for statistical computing with core functionality and the survival, smwrBase, and smwrQW packages. Predictor...
