New Flood Warning Maps for Kansas and Missouri

A new interactive flood map introduced by the U.S. Geological Survey, will help emergency managers from national, state and local agencies make quick decisions about when and how to evacuate residents threatened by rising floodwaters.

The flood-inundation maps, developed using USGS streamgages already in place, will enable better flood preparedness and response. The tool has been developed by the U.S. Geological Survey in cooperation with the City of Overland Park, Kansas, and the City of Kansas City, Missouri, have developed a new interactive online tool to improve flood warnings in selected parts of Kansas and Missouri.

The map features the Blue River and its tributaries, including Tomahawk and Indian Creeks in Johnson County, Kansas, and Indian and Brush Creeks in Jackson County, Missouri. The flood-inundation maps will encompass nearly 60 miles of the Blue River and its tributaries, and is the largest contiguous-mapped network of its kind in the country.

USGS Flood Inundation Mapping

The USGS Flood Inundation Mapping product is an interactive web-based tool that shows the extent of flooding at selected rivers and streams across the U.S. The maps illustrate where flooding is occurring, as well as areas that will likely flood in the near future. The flood-forecasting portion of the map is determined by using real-time USGS streamgage information and flood-forecast information by the National Weather Service (NWS). The mapping product can be found online.
