City of Colorado Springs / Stormwater / Flood InformationFlood Information
Flash flooding is the most common natural hazard in Colorado Springs. Flash floods tend to occur from May through September, and are usually caused by thunderstorms that are out of sight and hearing range of people downstream. Runoff from the mountains can quickly cause the water levels of small creeks and dry streambeds to rise to unsafe levels. These walls of water are fast moving and can easily reach heights of 10-20 feet. Know which streams and waterways are nearby, and where you are in relation to them.
You should never attempt to cross an area that is flooding. It only takes 6 inches of fast moving water to knock you off your feet. Just 10 inches of moving water can move a car, and 18 inches can float your vehicle. Your best course of action is to immediately seek higher ground.
An urban and small stream advisory means that isolated flooding of streams, streets, and low-lying areas, such as railroad underpasses and urban storm drains is occurring.
A flash flood watch means that flash flooding is possible. Be alert and prepared to move to high ground. Watch for rising water levels or unusual street flooding is possible. Listen to local radio or television stations or Weather Service radio for possible flash flood warnings and bulletins. Locate a hand crank or battery powered radio and extra batteries.
A flash flood warning means that a flash flood is occurring or is about to occur. If necessary relocate immediately and seek high ground away from high risk areas and water. Do not attempt to cross moving water either on foot or in your vehicle.
