Strait of Juan de Fuca Complex Land use in the Straits of Juan de Fuca complex (West Twin River, East Twin River, and Deep Creek) has been forestry since early in the 20th century. As a result, much of the wood that historically created pools and regulated the movement of sediment and organic matter in these watersheds had been depleted. Wood loss contributed to channel incision at some sites, isolating the floodplain and reducing access to off-channel habitats.
