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.

Regional analysis of the dependence of peak-flow quantiles on climate with application to adjustment to climate trends Regional analysis of the dependence of peak-flow quantiles on climate with application to adjustment to climate trends

Standard flood-frequency analysis methods rely on an assumption of stationarity, but because of growing understanding of climatic persistence and concern regarding the effects of climate change, the need for methods to detect and model nonstationary flood frequency has become widely recognized. In this study, a regional statistical method for estimating the effects of climate variations...

A framework for understanding the effects of subsurface agricultural drainage on downstream flows A framework for understanding the effects of subsurface agricultural drainage on downstream flows

Understanding controls on streamflow volume and magnitude is important to water resource management applications, such as critical water and transportation structure design and floodplain mapping. Changes in land use and agricultural practices, such as subsurface agricultural drainage, may be contributing to changes in streamflow characteristics. Subsurface agricultural drainage, also...

Assessing microplastics, per- and polyfluoroalkyl substances (PFAS), and other contaminants of global concern in wadable agricultural streams Assessing microplastics, per- and polyfluoroalkyl substances (PFAS), and other contaminants of global concern in wadable agricultural streams

Microplastics, per- and polyfluoroalkyl substances (PFAS), antibiotic resistance genes (ARGs), pharmaceuticals and personal care products (PPCPs), and pesticides may lead to unintended environmental contamination through many pathways in multiple matrices. This statewide, multi-matrix study of contaminants of global concern (CGCs) in agricultural streams across Iowa (United States) is...

Beyond the Usual Suspects: A Comprehensive Look at Agricultural Stream Contaminants

Clean water is essential for both environmental health and human safety, but many everyday products and activities can contribute to water pollution including contaminants such as microplastics, harmful chemicals such as pharmaceuticals and pesticides, and antibiotic resistance genes. A recent USGS study in Iowa investigated pollutants in streams, including stream sediment and biota, to determine...

Wings of Change: The Environment's Influence on Bird Flu

Low pathogenic avian influenza (LPAI) viruses naturally occur in wild birds and are rarely fatal. Highly pathogenic avian influenza (HPAI) viruses are highly contagious, spread rapidly, are often fatal to poultry, and have been responsible for worldwide outbreaks. Together, LPAI and HPAI are generally referred to as either avian influenza viruses (AIVs) or "the bird flu."

Preliminary Research Sheds Light on Proper Analysis and Sample Handling for the Tire-Derived Contaminants 6PPD and 6PPD-quinone

Tire and road wear particles have been shown to cause acute effects to sensitive aquatic animals and degrade their habitats. U.S. Geological Survey (USGS) scientists developed methods to accurately identify aquatic compounds, such as 6PPD and 6PPD-quinone, that can cause acute mortality events in coho salmon (Oncorhynchus kisutch).
