The North Fork Klaskanine is a major tributary to Young’s Bay and the first major watershed that ocean-returning fish encounter in the Lower Columbia River. The North Fork has received limited attention for habitat restoration due to passage impediments at ODFW’s Klaskanine Fish Hatchery. ODFW and USFWS partnered to complete survey and passage assessments at the hatchery and on the North Fork Klaskanine and its tributaries to explore opportunities to maximize Pacific lamprey and fish passage and restore stream connectivity while maintaining hatchery management. This led to the 2020 removal of one hatchery dam on the North Fork Klaskanine and verified presence of Pacific lamprey. Funding is requested to restore passage at a second hatchery dam on the North North Fork Klaskanine to improve access to 4.7 miles of habitat. The project will build a roughened channel to backwater the dam and provide full fish passage through the constructed riffle and over the dam. The roughened channel will extend ~260 feet downstream from the dam crest at a 3.5% slope. The constructed riffle will provide fish passage for all life history forms of all native species including Pacific and western brook lampreys. The base of the dam will be buried, but not removed. The diversion will continue to meet hatchery needs and the fish screen will meet regulatory requirements.
