Minnesota Enhanced Flood Forecast/Warning System




Thirty-eight stream gages were installed statewide, and five gages of the U.S. Geological Survey (USGS) were upgraded as a result of a federal/state grant that was obtained by the Minnesota Division of Homeland Security and Emergency Management (HSEM, formerly known as the Division of Emergency Management, or DEM). The grant request (valued at almost $1 million) was submitted to the Federal Emergency Management Agency (FEMA) and the Minnesota State Legislature in response to extreme flooding events in the 1990's, which would have been less damaging with more data available in the affected watersheds. An interagency task force, which primarily consisted of HSEM, the Minnesota Department of Natural Resources (DNR), the National Weather Service (NWS), and the USGS, surveyed flood-prone communities to determine their willingness to participate in improving their response to flooding. The task force then prioritized the potential sites based on the need for more data in specific watersheds.

This project demonstrates cooperation between the agencies and communities:


Gage Details

Each gage is equipped with satellite telemetry to provide real-time information to the NWS, local officials, HSEM, DNR, USGS, and the U.S. Army Corps of Engineers. Optional telephone lines allow the gage to call predesignated local officials of impending flooding conditions.

Specifics on each stream gage, and near real time data, can be found here.
