Flood Information

Lake County has three major river systems that either run the entire length of the county, or impact a portion of it. Therefore, we are susceptible to flooding. In Spring 2013, Lake County experienced historic major flooding on the Chain O'Lakes and the Des Plaines River.

How do we prepare and respond?  

Before the flood: Preparedness begins at home. Property owners should know if they live in a flood prone area and take steps to prepare. Learn more at Alert Lake County.

During the flood: Local municipalities and townships are often the first responder in a flood event. They provide various resources, including: sandbags and sand, road closures, evacuation of impacted areas, sheltering, law enforcement, clean up kit distribution, debris management and removal, and damage assessment.

The Lake County Emergency Operation Center is activated during a significant flooding event and numerous departments (Emergency Management Agency, Public Works, GIS, DOT, Health Department, Sheriff's Office, Planning, Communications, and Stormwater Management) work together to coordinate resources, including volunteers, equipment, sandbags, dumpsters for debris removal, and clean-up kits.

After the flood: The Emergency Management Agency (EMA) works closely with the Health Department and Planning Building and Development Department on health and safety issues, ensuring that it's safe for residents to reoccupy their business and homes. EMA is also responsible for providing an overall picture of the flood situation to Illinois EMA and FEMA in the event that disaster assistance may be available.
