The Clallam River is unusual in that sands and gravels frequently block the river's mouth. The river's lower course runs parallel to the sea, behind the gravel bars. Over the years the river repeatedly breaks through the barrier in different places, usually during periods of high stream flow. Sometimes migrating fish are trapped behind gravel barriers at the river's mouth. In July 1998 significant numbers of Steelhead trout were trapped in this way. The Pacific Coast Salmon Coalition had a channel cleared through the gravel bar, allowing the fish to escape.
