Our Mission

 

The Office of Water Resources is the lead state agency for water resources planning, navigation, floodplain management, the National Flood Insurance Program, water supply, drought, and interstate organizations on water resources. Interagency duties include the state water plan, drought response, flood emergency situation reports, and the comprehensive review of Illinois water use law.

 

The primary capital activity of the office is in the area of urban flood damage reduction. The office assists units of local government with urban flood damage reduction projects through planning, design, construction, and financial assistance. The urban program also features the acquisition of flood prone homes and businesses.
