* WHAT...Heavy snow possible. Total snow accumulations between 10 to 18 inches possible. Winds could gust as high as 35 mph. * WHERE...Northern and Central Oregon Cascades. * WHEN...From late Tuesday night through Thursday afternoon. * IMPACTS...Roads, and especially bridges and overpasses, will likely become slick and hazardous. * ADDITIONAL DETAILS...Latest guidance suggests the heaviest snow accumulations are forecast over the Cascades from Marion to Lane Counties. There is a 50-75% chance snowfall rates will occasionally exceed 1 inch/hour along the Cascade passes between 4 PM Wednesday and 8 AM Thursday, resulting in hazardous travel conditions due to a combination of low visibilities and accumulating snow.
Summary
The ideal streamflow range for this run is between 350 and 800 cubic feet per second (cfs). This flow rate allows for the rapids to be challenging yet navigable.
The class rating for this run is Class III, with some sections approaching Class IV. The run covers a distance of approximately 7 miles and features several significant rapids and obstacles. Notable rapids include the Toilet Bowl, which requires precise navigation to avoid being caught in a whirlpool, and the Pinball Rapid, which features several large boulders that create challenging whitewater.
There are specific regulations in place for this area. All boaters are required to obtain a permit from the Forest Service before entering the river. Motorized boats are not allowed on this section of the river, and all boaters must wear a personal flotation device at all times.
Overall, the Whitewater River run from Timothy Lake Dam to Slackwater of Harriet Lake is a challenging and exciting destination for experienced whitewater paddlers. It is essential to check the current streamflow and weather conditions before heading out, as water levels can change rapidly.
