PNWA is a collaboration of ports, businesses, public agencies and individuals who combine their economic and political strength in support of navigation, energy, trade and economic development throughout the Pacific Northwest.
Established as Inland Empire Waterways Association (IEWA) in 1934, PNWA’s first act was to petition President Roosevelt and Congress for funds to secure a navigation lock at Bonneville Dam. PNWA then led the way for Congressional authorization and funding to build the remaining seven locks and dams on the Columbia and Snake Rivers.
In 1971 we expanded, adding Puget Sound and coastal members to provide a comprehensive regional perspective. Our membership has grown to include public ports, tug and barge companies, steamship operators, grain elevator operators, agricultural producers, forest products manufacturers, electric utilities, irrigation districts, other businesses, public agencies, and individuals throughout Washington, Oregon, Idaho and Northern California.
With 80 years of experience at the helm, PNWA works to ensure that our waterways are efficient, reliable, and environmentally sustainable.
