* WHAT...Flooding caused by excessive rainfall continues to be possible. * WHERE...Portions of northwest and west central Washington, including the following counties, in northwest Washington, Clallam, Grays Harbor, Jefferson, Kitsap, Mason, Skagit and Whatcom. In west central Washington, King, Lewis, Pierce, Snohomish and Thurston. * WHEN...From 10 AM PST this morning through Thursday afternoon. * IMPACTS...Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Creeks and streams may rise out of their banks. Flooding may occur in poor drainage and urban areas. Storm drains and ditches may become clogged with debris. Area creeks and streams are running high and could flood with more heavy rain. * ADDITIONAL DETAILS... - A series of weather systems this week will bring another round of significant rainfall to western Washington through Wednesday. Preliminary liquid totals of 2 to 6 inches, locally higher in some spots, will cause additional sharp rises to area rivers. Urban and small stream flooding remains possible for areas with poor drainage. Very saturated soils will maintain increased risk for potential landslides and debris flows off of burn scars. - Http://www.weather.gov/safety/flood
Summary
The ideal streamflow range for this segment is between 1,500-4,500 cubic feet per second (cfs), which provides Class III-IV rapids. The total segment mileage is 7.2 miles, with a gradient of 87 feet per mile. The rapids on this segment include Corkscrew, Rattlesnake, and Kautz Creek Falls.
Specific regulations to the area include a required permit for all commercial and private rafters, which can be obtained through the National Park Service. Additionally, all boaters are required to wear appropriate personal flotation devices (PFDs) and follow Leave No Trace principles. The area is also designated as a Wild and Scenic River, which means that certain restrictions apply, such as no motorized boats and limited group size.
It is important to note that the Whitewater River Run can be dangerous and should only be attempted by experienced whitewater paddlers. Water levels can change rapidly, and there are many hazards, including undercut rocks and strainers. It is recommended that boaters scout the rapids before attempting them and that they paddle with a group of experienced paddlers.
