Flood Risk Infrastructure

Maintenance of flood risk infrastructure is key in maintaining the risk reduction provided by dams and levees. Living behind levees or downstream of a dam provides a unique type of risk.

The National Levee Database (NLD) is a database of levees which were constructed by USACE or are involved in the USACE PL 84-99 program (not all levees are presented in this database).

Other Data Sources

The National Weather Service (NWS) Advanced Hydrologic Prediction Service provides current and historic information about flood stages at several sites throughout Iowa.

Ice Jams create natural dams which cause localized flooding. Ice Jam flooding is characterized by rapidly increasing river stages that can be significantly higher than normal.
