North Cascades NP – Late last week, a major Pacific storm brought rain and high winds gusting to 70 mph to the area. On Thursday and Friday, as much as 10 inches of rain fell in 48 hours in areas on the west side of the Cascades. The high winds caused downed trees and major power outages throughout the area; the extensive rains caused rivers and streams to overflow their banks and closed many roads. A series of mudslides, including one that took out a 150 foot section of road near Diablo Lake, closed the North Cascades Highway (State Route 20) for the season. This closure is the earliest in the highway’s 31-year history. The heavy rains caused rocks to tumble onto roads and block culverts, felled trees across roads and caused mud to slide off hillsides in several areas throughout Ross Lake NRA. Fisheries biologists expect that the high stream and river flows will result in a large reduction in survival of pink and federally listed chinook salmon in the Skagit River system. The return of chinook salmon three to four years from now will consequently be much lower than otherwise, and the return of pinks in 2005 will be severely reduced. Park staff assisted numerous stranded visitors and supported staff members and local jurisdictions with evacuations of low lying areas. Rangers were called to assist in a search for two local men who went to check their cabin in the Bacon Creek area on the Mt. Baker-Snoqualmie National Forest just west of the park boundary. The men were found on Monday morning after having been stranded in their cabin by high waters for over 16 hours. Park staff have begun the process assessing damages. Another Pacific storm is hitting the area at present, bringing another bout of high winds, heavy rains and further flooding.
