Rockford Scanner™: Illinois State Water Survey to analyze flood risks



Illinois State Water Survey to analyze flood risks


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

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, began in late January
2022 and is expected 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. Surveyors from the
Illinois Department of Natural Resources are scheduled to begin work on Madigan
Creek in Rockford this week and could last several weeks.

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