Grangeville Dam (Harpster Dam) | 1963 | Idaho County | South Fork Clearwater River | This long arched concrete hydroelectric dam was constructed by the Washington Water Power Company in 1911. A wooden fish ladder had been installed but it collapsed in 1949. The dam was removed in the interest of fish passage and since the hydropower facilities had become obsolete. The dam was destroyed by dynamite at 6:35 PM on August 19, 1963, following two prior detonations that day which had failed to collapse the structure.[2] At the time, the dam was the largest ever to be removed, a record which stood for decades.[3] | ||
