Acoustic instruments are increasingly being used to measure suspended-sediment concentration (SSC) in fluvial environments. The USGS Office of Surface Water, USGS Sediment Acoustics Leadership Team, and the Federal Interagency Sedimentation Project are developing standardized methods and software for estimating SSC from acoustic backscatter from acoustic Doppler current profilers (ADCPs).
Valuable hydraulic data such as water levels, estimates of discharge, inundated areas, etc., can be extracted from photos and movies taken by engineers and scientists that can be used to help improve the analysis and understanding of flood hazards.
Approved Mean Annual Discharge
The stream flow monitoring station on the Chicago Sanitary and Ship Canal near Lemont, Illinois has been in operation since December 7, 2004. The site is operated in cooperation with the U.S. Army Corps of Engineers, Chicago District, Chicago, Illinois.

A water conditions summary table that includes historical and current river stage data and combines National Weather Service forecast river stages for stream-monitoring sites in Illinois is available. The table is updated every 30 minutes and the stream-monitoring sites are operated by various agencies. River stages above flood stage are shown in red to help monitor flooding conditions. ...
The USGS Central Midwest Water Science Center (CMWSC) is comprised of water science offices in Illinois, Iowa, and Missouri.
The MOWSC conducts research and monitoring on a wide variety of hydrologicial issues affecting steams, rivers, lakes, and groundwater in our three states and across the Nation.
Real-time precipitation data is available in our map-driven application for Illinois. You can use a map to select a precipitation-monitoring site and view precipitation amounts for the previous 3,6,12,24,48 hours and 7,14, and 30 days. A data table shows precipitation amounts at all sites within the state.

To monitor fish movement in selected rivers, the USGS has installed near real-time receivers for fish tags. These receivers detect the presence of acoustic tags that have been surgically implanted into a variety of fish species. The tag detection data can provide information about how far fish are moving in a river system, changes in fish population distribution, and, when viewed with flow and...

We have installed webcams at a number of locations in the Central Midwest Water Science Center to allow you to view, in real time, the current conditions. Some of the cameras allow users to temporarily control the tilt, pan, and zoom. During periods of flooding the Central Midwest Water Science Center may take control of the camera.
Assessing the uncertainty in model estimated streamflows: A case study using watersheds and rain gage network in Chicago metropolitan area- David T. Soong
The intern will benefit through professional growth gained by academic training in hydrologic science, statistical analysis, and numerical modeling. The intern will also benefit from mentoring opportunities with the PIs and other USGS scientists; with academic professionals at University of Illinois–Urbana, and potential co-authorship on one or more scientific publications.
This is an interdisciplinary project linking stream ecology and hydraulic engineering. The intern will join a team to conduct scientific research on a “hot-topic problem” that has gained national attention and will benefit by gaining exposure to a real-world problem that perhaps cannot be found in textbooks.
