Non-motorized Boaters

Portage of non-motorized recreational craft and other vessels isunsuitable for lockage is the preferred method of transport around dams. Non-motorized craft on the Columbia River may be locked through if moored to a motorized assist vessel. On the Snake River, non-motorized craft may be locked through without an assist vessel when no spill is occurring. For portage information, visit the portage guide.
