Illinois Highlights

Initial Results from a Reconnaissance of Cyanobacteria and Associated Toxins in Illinois, August-October 2012

During the drought of 2012, cyanobacteria was recognized to be a concern in Illinois lakes and rivers. The USGS and the Illinois Environmental Protection Agency completed a reconnaissance data collection effort and have published an Open-File Report summarizing initial results of the currently available data in support of a public meeting. Stay tuned to this website for additional developments.

Drought of 2012

The Drought of 2012 is affecting streamflow conditions and other hydrologic parameters in Illinois. The USGS Illinois Water Science Center is providing important water-resources data to water management officials, the public, and researchers during the Drought of 2012. You can access the data directly through the sidebar on the left for the most recent data. Or you can go through a map interface for real-time streamflow, precipitation, and water quality, and all groundwater measurements by clicking which type of data you would like. Additionally, field staff from the Illinois Water Science Center have been collecting low-flow discharge measurements and observations from streams throughout Illinois. Download and view the measurements and observations spreadsheet.
