Walnut Creek, North Walnut Creek, and Little Walnut Creek are central to the City of Clive and make the City unique. These waterways are prone to flash floods and urban street flooding. Flooding is a natural process and inevitable. Click here for the Be Flood Ready brochure.

Flood Warning System. The City of Clive works in partnership with other communities (Des Moines, Urbandale, and West Des Moines) and the National Weather Service (NWS) to operate an Automated Flood Warning System for Walnut Creek.  The system of telemetered rain gauges, river gauges, and receivers is operated jointly by NWS and the City of Des Moines. 

The system provides constant real time access to flooding threat events along Walnut Creek and North Walnut Creek.  The automated system provides alert information to key city personnel based on pre-defined threat levels as identified in the City’s Flood Response and Recovery Plan.   Based on the USGS gauge at I-35/80, the NWS provides predictive information regarding anticipated timing and crest.

Additionally, Clive has 4 gauges with real-time information at the Iowa Flood Information System. Click on the IFIS icon below to access the website; an instructional video is available on the home page.
