CHAMPAIGN, Ill., 1/27/22: Illinois State Water Survey (ISWS) hydrologic and hydraulic modeling in Boone, DeKalb, Ogle and Winnebago Counties, Illinois is underway as part of a study to help local communities identify areas of high flood risk for flood mitigation planning.

ISWS is working collaboratively on the project with the Illinois Department of Natural Resources-Office of Water Resources (IDNR-OWR) and the Federal Emergency Management Agency (FEMA).

The first phase of the project, data collection, is anticipated to begin in late January and to be completed in summer 2022. In this phase, surveyors will conduct detailed channel and bridge surveys of the river, including in or near the cities of Rockford (Winnebago County) and Belvidere (Boone County) and Villages of Cherry Valley (Boone and Winnebago counties), Davis Junction (Ogle County), and Kirkland (DeKalb County).

Field survey activities will primarily be focused on Bull Creek, Killbuck Creek, Kishwaukee Tributary A, Kishwaukee Tributary A Stormwater Diversion, Madigan Creek, Manning Creek, and South Branch Kishwaukee River.

Residents should be aware of the periodic presence of survey crews in the area. Surveys will be completed as stream conditions and weather allow.

Questions about the study can be directed to Aaron Thomas, P.E., CFM, at the Illinois State Water Survey (abthomas@illinois.edu) 217-333-7832.
