* WHAT...Flooding caused by excessive rainfall continues to be possible as a result of regulated reservoir and dam operations. * WHERE...A portion of west central Washington, including the following counties, King, Lewis and Pierce. * WHEN...Through Saturday morning. * 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... - Regulated rivers may continue to remain elevated or increase as reservoirs and dam operators manage the water levels. River flows downstream of dams may rise or lower rapidly as a result. Dam regulations can change rapidly to account for incoming water. - http://www.weather.gov/safety/flood

Summary

The ideal streamflow range for this section of the river is between 700-1500 cfs. The segment covers approximately 8.1 miles and is rated as class III-IV rapids.

Some of the specific rapids and obstacles to watch out for include "Pinball" and "S-Turns." The Pinball rapid is named for its resemblance to a pinball machine as the water bounces off of rocks and creates a challenging obstacle course. The S-Turns rapid is a series of sharp turns that require quick maneuvering.

There are specific regulations in place for this area, including a requirement for a permit to enter the Alpine Lakes Wilderness. Additionally, all motorized boats are prohibited on the river.
