Flooding
What You Should Know During Flood Threats
The Walnut Creek is known for flash flooding. Flash flooding is a term used for small streams and creeks that are susceptible to quick rises in stream levels. As quick as these water levels reach their peak (crest) they begin to recede. Walnut Creek reaches from the City of Clive northwest to Dallas Center and stretches out between Grimes and Waukee. This is approximately 10 miles between Dallas Center and I –35/80. It is important to understand that only heavy rains within the Walnut Creek watershed will have an impact on flooding within the City of Clive.

If you are a homeowner or business owner in the City of Clive and you live or work within a flood prone area, pay close attention to heavy rain fall events within the watershed. Typical heavy rainfall events take place between May and June, but we have had major flood events in late winter and late summer as well. It is important you stay informed to the latest weather reports and information during wet weather periods. A NOAA weather radio will alarm you during the late evening and early morning. If you are at work, listen to the radio or access the NOAA Des Moines Internet site for the latest watches and warnings. Click here for information on local flooding.
