* WHAT...Flooding caused by excessive rainfall continues to be possible. * WHERE...Northwest Oregon and southwest Washington including the following counties. In Oregon: Benton, Clackamas, Clatsop, Columbia, Hood River, Lane, Linn, Lincoln, Marion, Multnomah, Polk, Tillamook, Washington, and Yamhill. In Washington: Clark, Cowlitz, Pacific, Skamania, and Wahkiakum. * WHEN...Through Saturday afternoon. * IMPACTS...Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. 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. Landslides and debris flows are possible during this flood event. People, structures, and roads located below steep slopes, in canyons, and near the mouths of canyons may be at serious risk from rapidly moving landslides. * ADDITIONAL DETAILS... - An atmospheric river is forecast to bring periods of heavy rain to northwestern Oregon and southwestern Washington today. This system occurs at a time when area rivers continue to run high and soils remain saturated following heavy rain earlier in the month. During initial heavy rainfall today, the urban and small stream flooding threat will be most urgent, although the details of precise timing and location of the highest risk remains uncertain at this time. As runoff works its way downstream, the river flooding threat will increase tonight into Friday, with numerous area rivers now forecast to reach at least Minor flood stage. Slower reacting rivers may stay in flood stage into Saturday afternoon. - http://www.weather.gov/safety/flood
The ideal streamflow range for this run is between 500-1000 cfs, with peak flow in late winter and early spring. The class rating for this section of the river ranges from Class III to Class IV, with some challenging rapids and obstacles such as "Suicide Falls" and "Boulder Garden."
The segment mileage of this run is approximately 10 miles, making for a great day trip. However, it is important to note that there are specific regulations in place for this area. A permit is required for all river users, and camping is only allowed at designated sites. Additionally, there are restrictions on the use of motorized boats and other watercraft.
It is important for anyone considering this run to have experience in whitewater paddling and to have the proper equipment, including a helmet and personal flotation device. The river can be unpredictable and dangerous, so caution and preparation are key.
