SALT LAKE CITY (ABC4 News) – Another tragedy, floodwaters rip through Goblin valley killing a 7 year old, and her 3 year old sister.
Floods statewide have claimed lives for more than 100 years.
When it rains our mountains and canyons become extremely dangerous, especially in Southern Utah. This area of the state can be the most deadly, the beautiful red rocks harbor the densest population of slot canyons in the world. Over 1000 of them south of Interstate 70.
The slot canyons are found in Zion National Park, Canyonland’s National Park, Capitol Reef National Park, inside the San Rafael Swell, and the Grand Staircase-Escalante National Monument, with a concentration along the Escalante River drainage including Coyote Gulch.
According to the National Weather Service flash floods occur within a few minutes or hours of excessive rainfall, a dam or levee failure. Sudden releases of water held back by ice can cause the violent runoff too.

You wouldn’t think the rainfall would have that much power, but as it collects and starts moving over the barren ground it gets stronger and stronger. The NWS says the floods can roll boulders, tear out trees, destroy buildings and bridges, and literally dig themselves a new route. The water rises so fast it can reach heights of 30 feet or more.
The truly terrifying part? You don’t always get a warning the sudden deadly flood is coming. Most flood deaths are caused by flash floods.
Over the last 100 years Utah has experienced several deadly flooding events. The events happen throughout the state and we have had more people killed since 1970 as the sport of canyoneering has become more popular.

Officials urge flood safety wherever you are in Utah.
A pamphlet is available about floods and what you should know about the dangerous waters living in Utah.
The pamphlet says to remember six inches of moving water can knock you off your feet. 2 Feet of water will float your car. Never swim or drive through such swift water. If you come upon flood waters, stop! Turn around and go the other way.
