The Lower Columbia River Water Trail is a 146-mile, bi-state trail spanning the tidally influenced river waters from the Bonneville Dam to the Pacific Ocean. This water trail was dedicated in the summer of 2004. Work is ongoing surveying, working with landowners, and publicizing launch and landing sites, campsites, and other facilities for non-motorized boaters (those generally using kayaks, canoes, small rowboats, etc). The new website has a GIS-based map and increasing amounts of information for those traveling on the Lower Columbia.
