Episode narrativeepisode_narrativeA wet spring season continued for the Inland Northwest during the last week of May as another, wet storm system moved through the region producing in the neighborhood of half to one and a half inches of liquid precipitation over Northern Washington May 25-26th. Many basins were already swollen from wet conditions and excessive snowmelt earlier in the month and soils were very saturated and unstable in some locations. As a result, rivers, small streams, and creeks continued to rise near bankfull to above flood stages. Additionally, several landslides occurred in the Okanogan National Forest.
Event narrativeevent_narrativeA massive landslide occurred in the Pearrygin Lake area just outside Winthrop, WA|on the afternoon of May 31st. The Okanogan Sheriff's Office reported that the landslide was about 40 acres long and covered 200 yards of Walter Road and majority of a property located at the end of Walter's Road. The mudslide damaged and spun the homeowner's travel trailer around, damaged a hot tub, pushed a pickup truck 75 feet, but missed his home by 50 feet. The property owner stated that he had roughly 13 thousand in property damage; 40-60 thousand in cleanup cost; and additional loss due to the range and alfalfa fields being covered in mud and large logs. The property owner estimated it would be three years before the fields could be planted again. Agriculture losses were estimated to be near 17 thousand dollars over the three year period. The slide may have also compromised the aquafer in the area. Springs which fed the aquifer were torn apart and are currently running down the top of the slide much like a stream. Residents in the area are digging new holding ponds to mitigate the loss of spring water. Additionally, a U.S. Forest Service vehicle and four employees were trapped behind the slide but were able to walk through the slide that afternoon and return to town. The slide was believed to be caused when Pearrygin Creek got dammed upstream and changed course toward Walter Road. There were no injuries.
