DuPage County Stormwater Management uses the United States Geological Survey (USGS) stream and rain gages, as well as a local stream gages. The stream gages show real-time observations of stream height and discharge. USGS compiles these measurements hourly. The rain gages provide information about precipitation totals in the last week, as well as a link to the USGS station page.

Flood Forecast Simulations
Using real and forecasted precipitation and stream levels, DuPage County Stormwater Management models rain totals countywide. They are simulated using provisional data, and actual watershed conditions may vary. All local agencies should use individual judgment when making operating decisions
Simulations have been run at each of the below locations. In addition, County staff provides simulation notes. Further information regarding individual sites can be accessed by visiting their respective hyperlinks.
