Flooding Flooding Flooding

Every year heavy rains make an appearance in Colorado.  Sometimes in the form of spring showers other times in the way of Summer Monsoons.  As a child I remember cutting milk cartons in half to make homemade boats to float down the swollen gutters along the street outside my  house.  I also remember the fresh smell of rain in our crisp mountain air.

As an adult however, heavy rainfall typically means something all together different for me.  I still love the smell of rain in the air and of course my lawn perks up after being quenched by an afternoon shower. But now, especially with the devastation that wildfires have brought to the vegetation and Colorado countryside, I now think of "flash floods."  Flash floods in areas like these can cause dangerous mudslides that can carry away people, cars and even houses.

Flash floods are of course not limited to the areas affected by wildfires.  Heavy rainfall in Colorado cities can quickly overwhelm even the most well maintained city streets.  Low lying areas swiftly become flooded with deep pools and fast moving washes of water.  These murky waters hide many dangers. Hidden culverts and grates over storm drains that were meant to channel water from these very same streets, lay in wait for the unsuspecting passerby to venture too close and become sucked into these death traps with unrelenting force.  This phenomenon is referred to as "Delta P" and has been the cause of many a tragic drowning.  One of the most well known incidence of this was the August 17th 2000 drowning death of Denver Firefighter Robert Crump.

On the evening of August 17th, firefighter Crump was with his crew when he was called to an improvised rescue in the middle of a city street flooded with water.  Firefighter Crump was tragically swallowed up by water on the flooded street as it followed the path of least resistance down a 12 foot culvert.  The weight and velocity of the water compounded to create forces much to strong for any person to fight against.   Firefighter Crump was swept away that day.  Just as dangerous as any other aspect of flash floods, hidden storm drains and culverts shout watch out to anyone who considers wading down city streets that are flooded with rain water.

One reason firefighter Crump and his crew were working on these flooded streets were the large number of vehicles littering them.  Drivers are either unaware of the dangers of flooded streets or fail to recognize such a danger prior to reaching the point of no return.  It takes 9 inches of moving water to sweep a person off their feet, and less than two feef of water to carry even an SUV off the roadway and down stream to certain danger.

Many Public Safety Announcements (PSA's) have been done portraying the dangers of driving into low lying areas where waters have floodfed the roadway.  One popular safety message is "Turn around don't drown.)  Please take a moment to visit this video and heed it's warning.

Remember these flash flood and water safety tips.

• Never wade on flooded streets.  These muddy waters can hide storm drains and culverts that can sweep you off your feet.
• 9 inches of moving water can sweep you off your feet.
• Turn around, don't drown.
• less than 24 inches of water can float your vehicle from the roadway and downstream to certain danger.

Let's all make it home to enjoy the fresh smell of rain from our porches, and show our kids how to make boats out of milk cartons.
