About PNWA

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.

PNWA introduces new look in 2016

This new look is meant to express our membership’s Northwest heritage, while
keeping the professional look for which we are known.  As we prepare to celebrate
our updated image, we thought you might like to see a collection of our past and
present identities from the last 82 years!


1934-1971 – This letterhead shows PNWA’s logo from when we were still the Inland Empire Waterways Association.  As the logo shows, we were based in Walla Walla at the time.



In 1971, the Inland Empire Waterways Association and the Northwest Rivers and Harbors Congress merged to form the Pacific Northwest Waterways Association.  The expansion brought Puget Sound and coastal members together with the inland river groups to be the organization you are all a part of today.








In a series of iterations, updated in 1981, 1993 and 2000, this logo was used for our association until 2005.
It made use of a stylized version of mountain and water elements.


The last redesign in 2005 was the most drastic. It dropped the elements of the rivers and mountains in favor of a stylized capitol building. The goal was to emphasize PNWA’s federal presence and the work we do in DC.




Our new logo is modern, yet references the logos from the original two groups that merged to form PNWA. The picturesque mountain, tree and water scene refers to PNWA’s respect for the environment and our  Northwest focus. The ship ties back to the logos of our founding organizations.  The all-caps font is classic and comfortable, works well in small formats like co-branded marketing, and reads easily in internet and social media formats.  The navy blue matches PNWA’s most recent logo, and the turquoise adds interest. The logo works equally well in color and black & white.
