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.

Dynamic rating method for computing discharge from time-series stage data

Ratings are used for a variety of reasons in water-resources investigations. The simplest rating relates discharge to the stage of the river. From a pure hydrodynamics perspective, all rivers and streams have some form of hysteresis in the relation between stage and discharge because of unsteady flow as a flood wave passes. Simple ratings are unable to represent hysteresis in a stage/discharge rel

Water quality in the Missouri River alluvial aquifer near the Independence, Missouri, well field, 1997–2018

Groundwater-quality data collected from 1997 through 2018 from 68 monitoring locations open to the Missouri River alluvial aquifer (hereafter referred to as the “alluvial aquifer”) near the Independence, Missouri, well field were analyzed by the U.S. Geological Survey, in cooperation with the City of Independence, Missouri. This analysis was done to assess the quality of the water in the alluvial

Central Midwest Water Science Center— Harmful Algal Blooms team

The U.S. Geological Survey (USGS) Central Midwest Water Science Center (CMWSC) includes three States—Illinois, Iowa, and Missouri. USGS water science centers across the Nation provide information on water resources including streamflow, water use, water availability, and the quality of surface water and groundwater (https://www.usgs.gov/mission-areas/water-resources).The USGS CMWSC Harmful Algal B

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. Better proxies for identifying and predicting river HABs...

Iowa Alluvial Aquifer

This study is part of ongoing research in Iowa to investigate the availability (quantity and quality) of water in alluvial aquifers that are used for agricultural, domestic, municipal, and industrial supplies. Previous research included modeling and delineation of ground water flow in the Mississippi River, Des Moines River, iowa, and Cedar River alluvial aquifers. The water quality of these and...
