A report of fisheries investigations in Oregon coastal streams south of the Columbia River and exclusive of the Umpqua River

This report is a summarization of investigational work that has been completed since 1941 by the Oregon State Game Commission on the coast streams south of the Columbia River, exclusive of the Umqpua and its tributaries. The Umpqua river system was covered in another report prepared jointly by biologists of the Fish Commission of Oregon and the Oregon State Game Commission.\ud It is hoped that the facts presented here will help in an understanding of the problems involved and serve to make known the critically low levels of runs of anadromous fishes in the coastal streams. The report covers general observations, fish population studies, barriers and stream improvements, salvage problems, hatcheries and economic evaluations
