Tributaries of the Clearwater River, Washington, support substantial populations of overwintering juvenile coho salmon Oncorhynchus kisutch . In 1983, a 4‐year study was begun to determine if holes blasted in the mud substrate by explosives and subsequently flooded by creation of a small low‐head dam could enhance these habitats economically. After treatment, overwinter survival and growth of coho salmon increased significantly.
