Welcome to the USGS Illinois Water Science Center. These pages are your source for water-resource information collected and interpreted
by the U.S. Geological Survey in Illinois.
On the map to the left, point to one of the stream-monitoring locations to see a summary of current streamflow conditions, or click elsewhere on the map to open a larger view.
The Illinois Department of Transportation (IDOT) and the United States Geological Survey (USGS), in cooperation with the Illinois Center for Transportation (ICT), are working on a project to update important equations in the widely used StreamStats online tool. The project will produce Web-based peak flow estimates for all urbanizing watersheds in Illinois. read more
Thomas Over, hydrologist at the U.S. Geological Survey’s (USGS) Illinois Water Science Center, is currently serving as co-principal investigator on Illinois Center for Transportation/Illinois Department of Transportation (ICT/IDOT) project R27-144 “Development and Implementation of Updated Urban Regional Flood Frequency Equations for Illinois.” The objective of this research is to update the 1979 Illinois urban regional flood-frequency equations to current urbanized conditions and implement the resulting equations in StreamStats, a Web-based geographic information systems (GIS) application used in water resources planning and management and in engineering design. read more
“The researchers at the USGS Illinois Water Science Center in Urbana are uniquely positioned and qualified for this project, given both their staffing experience with hydrology and water resources projects and their management and familiarity with the stream gaging network in Illinois. BBS Hydraulics has partnered with USGS on several research projects—they deliver reliable, useful results in a very competent manner. Considering Illinois StreamStats is supported and maintained by the USGS national office going forward, IDOT is receiving a great bargain on a critical design resource.”

On the basis of their recent review of the human health effects of hexavalent chromium [Cr(VI)] in public drinking water, the U.S. Environmental Protection Agency is considering the need for Federal regulation of Cr(VI). Presently, only total chromium is regulated, at a Maximum Contaminant Level (MCL) of 100 micrograms per liter (µg/L). The occurrence of Cr(VI) in groundwater and surface waters generally is attributed to industrial sources, but can be of natural origin. California’s recently established MCL for Cr(VI) of 10 µg/L illustrates the drinking-water concerns associated with Cr(VI). To improve understanding of the possible impact of a Cr(VI)-specific standard that approximates the California level on the management of Illinois’ public drinking water, the U.S. Geological Survey, in cooperation with the Illinois Environmental Protection Agency, assessed the occurrence and distribution of Cr(VI) in the State’s public-water supplies.

The Fluvial Egg Drift Simulator (FluEgg) is a three-dimensional Lagrangian model that simulates the movement and development of Asian carp eggs until hatching based on the physical characteristics of the flow field and the physical and biological characteristics of the eggs. This tool provides information concerning egg development and spawning habitat suitability including: egg plume location, egg vertical and travel time distribution, and egg-hatching risk.
