The City of Scottsdale Fire Department has responded on several water rescue calls since 9 am this morning. Most of the calls are vehicles driving into the wash and stalling. There have not been any injuries reported. We are currently working a call at Hayden and Happy Valley. Please stay clear of the area. Do not enter a flooded wash. A mere 6 inches of fast moving water can knock down an adult. It takes 12 inches of rushing water to carry away a small car, while 2 feet of rushing water can carry away most vehicles. It is never safe to drive or walk into flooded waters.
