Thank you for visiting Stormwater Management's rain and stream gage site. These pages provide access to real-time water resource data collected throughout the county. There are currently 66 rain and 25 active stream gages throughout DuPage County. For the gages that are considered continously recording, results are collected every 15 to 60 minutes and then transmitted back to data stores located on-site. The recording and transmission times may be more frequent during critical events or when otherwise necessary.

USGS Cooperation

DuPage County works together with the United States Geological Survey to provide real-time data. Many of the precipitation and stream gages within DuPage County are monitored and maintained through a cooperative agreement with the USGS. Real-time data is transmitted from a USGS recording location to the County where it is presented on the following webpages.

In addition to the network within the county, there are a number of rain gages located outside of DuPage that are monitored and used in forecasting models to predict potential flooding events. Below is a table listing each gage and its location. Click the gage to view more detailed information. This will open a new browser window and bring you to the USGS website.
