Collawash River

From Wikipedia, the free encyclopedia

The Collawash River is a small remote river in Oregon's Cascade Range. It feeds into the Clackamas River.

The Collawash River is the largest tributary of the upper Clackamas River, with a main stem length of 11.6 miles and a basin area of 150 square miles. The stream provides one-third of the low flow volume of the Clackamas River. The entire Collawash River drainage is on National Forest System lands. About 35% of the watershed is in fully protected status as wilderness. Approximately 20% more is under protected riparian area status or is unsuitable for timber harvest. Overall fish habitat is rated good to excellent, with good holding and rearing habitat present throughout the system. ^[1]

For whitewater runners, the river is considered as two or three sections which range from class II to class V. Suggested flow range is 500 to 1000 cubic feet per second.^[2][3][4]
