CHAMPAIGN, Ill., 12/23/20: The Illinois State Water Survey (ISWS) announced today that new hydrologic and hydraulic modeling in Massac County, 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 January 2021 and end in the spring. In this phase, IDNR-OWR will conduct detailed channel and bridge surveys of the river within the county, including in the vicinity of the City of Metropolis. 

Water Survey activities will primarily be focused within the riparian corridor of Massac Creek from the confluence with the Ohio River (near Metropolis) up to Rosebud Road.

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 at the Illinois State Water Survey (abthomas@illinois.edu), 217-333-7832.
