2010: A continuous feed of moisture into the Mojave Desert triggered by a slow moving area of low pressure off the coast of the Pacific Northwest resulted in several days of moderate to heavy rain falling across southern Nevada, northwest Arizona and southwest Utah. This resulted in significant to major flooding on area rivers and washes. The Beaver Dam Wash reached major flood stage and flooded the community of Beaver Dam, AZ. Six homes in Beaver Dam Estates were washed away with one of the homes falling into the wash and floating 200 yards before it crashed into trees, split apart and sank. Another 12 homes were damaged, and two mobile homes and a garage were destroyed. A 300 to 400 foot stretch of Clark Gable Drive was washed out. The raging waters of the Beaver Dam Wash then flowed into the Virgin River which then flooded Littlefield, AZ where a sewer lift station was damaged. Further downstream on the Virgin River at Mesquite, NV flooding damaged a golf course, two homes, a diversion dam for an irrigation canal and 200 feet of reinforced concrete pipes which serve as the outlet for a detention basin. The Virgin River crested at 13.2 feet at the Scenic Bridge in Mesquite at 5:02 PM on December 23rd.
In California the Mojave River overflowed its banks between December 21st and 24th due to a combination of heavy rain and an emergence release of water from the Cedar Spring Dam near Arowhead. Numerous roads in and around Barstow were covered with mud and closed, one bridge was washed out, a broken levee flooded a Barstow neighborhood and 3 swiftwater rescues were performed in Yermo.
In addition, this series of storms produced heavy mountain snows between December 17th and December 22nd. Aspendell, CA measured 88.1 inches of snow while 96 inches was measured at the Las Vegas Ski and Snowboard Resort on Mt. Charleston, NV. At least 2 feet of snow fell on Westgard Pass in the White Mountains of California. The tremendous volume of snow crippled mountain communities with a "Code Red" declared by Inyo County for the eastern southern Sierra Nevada as people were advised to either stay put or leave before the snow set in. On Mt. Charleston at least 3 avalanches took place, and this combined with the volume of snow triggered evacuations. There were numerous downed trees and power lines and damages on the mountain alone were estimated at a half a million dollars from the snow.
Elsewhere across the area numerous roads were flooded. Valley of Fire, Echo Canyon and Spring Valley State Parks in Nevada were closed due to flash flooding. Total damages across the entire Las Vegas County Warning and Forecast Area were estimated at $13.5 million in 2010 dollars.
