Jetties at the Mouth of the Columbia River

PNWA is the lead organization advocating for the Jetties at the Mouth of the Columbia River. For over 100 years, these three rubble mound structures have helped to maintain the depth and orientation of the navigation channel to ensure safe passage for commercial and recreational mariners.  The U.S. Coast Guard Station Cape Disappointment also benefits from the jetties which help to minimize the dangerous conditions at the mouth. In 2015, the station launched 162 search and rescue cases, which saved 97 lives in the Area of Responsibility around the jetties. Without the jetties, there would be an increased need for a more active search and rescue presence.

The Columbia River jetties also help support the economy of our region and the entire country.  The Columbia Snake River System is the nation’s largest wheat export gateway, and second for corn and soy. It is also number one on the west coast for forest products, automobiles and mineral bulk exports, and in 2018, moved over 56 million tons of cargo valued at over $23 billion.  Over 40,000 local jobs are directly dependent on this trade.  The jetties are a vital part of ensuring our river is able to handle current cargo volumes and continue to grow.

In June 2012, the Corps completed their Major Rehabilitation Report (MRR) for these jetties.  An aggressive funding plan was identified and is now estimated at just under $240M if completed by FY2023.  The project received critical “new start” status in FY2014 and has received a total of $46.5M over the last four years, including funding to complete construction on Jetty A.  The project is proposed to receive $22M in FY2018, $11M of which will be used to complete construction on the North Jetty.  Funding requests in FY2019 and beyond will focus on construction of the South Jetty.  For more information, please contact or visit
