ESFSEW A series of atmospheric rivers will provide rounds of increasingly impactful rainfall starting on Friday and continuing through early next week. Snow levels will remain around 5000 to 6000 feet. Expect rising rivers with potential for flooding especially for rivers flowing off the Olympics and Cascades. Urban flooding and landslides are also possible throughout this period as the soil conditions remain wet.
The ideal streamflow range for this run is between 800 and 2,000 cfs. The class rating for this run is Class III-IV, with some Class V rapids depending on the water level. The segment mileage for the run is approximately 11 miles, starting at the confluence with the Taylor River and ending at the confluence with the North Fork Snoqualmie River.
There are several notable rapids and obstacles along the Whitewater River run. One of the most challenging rapids is called "Super Collider," which is a Class V rapid with multiple channels and large boulders. Another notable rapid is "Tom's Foolery," which is a Class IV rapid with a sharp left-hand turn.
There are specific regulations that must be followed in the area. For example, all boaters are required to wear a personal flotation device (PFD) and a helmet. Additionally, motorized vehicles are not allowed in the area.
