Stream Flooding

All rivers and streams, regardless of size, have the potential to flood. In the Fort Collins area, spring brings the greatest threat of flooding because of the combination of frequent thunderstorms and winter snowpack still present in the mountains and foothills. However, flooding is possible anytime during the period of May through September due to the frequency of rainfall during that period.

Principal flood sources in Fort Collins are the Cache La Poudre River, Spring Creek, Dry Creek, Fossil Creek, and Boxelder Creek, although flooding can occur in the smaller tributaries and canals throughout the city as well. If you live in a floodplain, the odds are that someday your property will be damaged. A floodplain homeowner with a 30-year mortgage has a 26% chance of being flooded.
