The Iowa Flood Center has utilized the state’s unusually mild start to winter by installing an additional 50 electronic stream stage sensors across Iowa.

These sensors, 100 of which have been installed throughout the state, use sonar to measure the distance to the water’s surface and determine water levels. They then report this data to the Flood Center’s headquarters at the University of Iowa every 15 minutes.

This data allows for real-time monitoring of water levels in Iowa’s rivers and streams, thus improving the center’s ability to predict flooding.

Check out the data produced by these sensors at the Iowa Flood Information System website, which provides a detailed map of Iowa flood conditions, along with forecasts, visualizations, inundation maps, and other flood related information.
