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.
