Central Midwest Water Science Center

Welcome to the Central Midwest Water Science Center’s (CMWSC) Website. We offer information on streamflow, water quality, water-use, and groundwater data for Illinois, Iowa, and Missouri. We conduct unbiased, scientific hydrologic investigations & research projects to effectively manage CMWSC and our Nation's water resources through joint efforts with our partners.

Bathymetric contour maps, surface area and capacity tables, and bathymetric change maps for selected water-supply lakes in north-central and west-central Missouri, 2020

Bathymetric data were collected at 10 water-supply lakes in north-central and west-central Missouri by the U.S. Geological Survey (USGS) in cooperation with the Missouri Department of Natural Resources and in collaboration with various local agencies, as part of a multiyear effort to establish or update the surface area and capacity tables for the surveyed lakes. The lakes were surveyed in June an

Bathymetric and velocimetric surveys at highway bridges crossing the Missouri and Mississippi Rivers near St. Louis, Missouri, August 3–10, 2020

Bathymetric and velocimetric data were collected by the U.S. Geological Survey, in cooperation with the Missouri Department of Transportation, near 15 bridges at 10 highway crossings of the Missouri and Mississippi Rivers near Washington, Louisiana, and St. Louis, Missouri, on August 3–10, 2020. A multibeam echosounder mapping system was used to obtain channel-bed elevations for river reaches abou

Method for identification of reservoir regulation within U.S. Geological Survey streamgage basins in the Central United States using a decadal dam impact metric

Researchers routinely study streamflow data to understand the effects of natural climate variability and anthropogenic climate change, and to develop methods for estimating streamflow at ungaged locations. These studies require streamflow data that are not modified or largely altered by other anthropogenic activities, such as reservoirs or diversions. This report discusses a method for identifying

Airborne Electromagnetic (AEM) Survey 2023 - Illinois River Basin

The U.S. Geological Survey (USGS) is conducting an Airborne ElectroMagnetic (AEM) Survey starting in late January 2023 and lasting three to four weeks. A helicopter towing a large hoop from a cable will begin making low-level flights over the Illinois River Basin, covering much of central Illinois and parts of northwest Indiana.

Bathymetry and Water-Quality of Surface Water Bodies in Cook County, Illinois

Surface water bodies in Cook County are used for stormwater detention, domestic and industrial uses, recreation, and commercial navigation. However, the bathymetry (elevation of the bottom surface) of most water bodies in Cook County has not been measured or mapped comprehensively. Similarly, water quality in most of these water bodies is unknown.

Harmful Algal Bloom Research and Monitoring - CMWSC

The Central Midwest Water Science Center (CMWSC) includes three states: Illinois, Iowa, and Missouri. The water science center is responsible for providing information on discharge, water quality, water-use, and groundwater data. The Harmful Algal Bloom (HABs) team is currently researching ways to better predict, analyze, and study HABs.
