Our first mission, eliminating impediments to navigation on the Pacific Northwest's rivers, dates back to 1871.

We maintain safe and reliable channels, harbors and waterways for the transportation of commerce, support to national security and recreation.

Before you go out on the water, get the forecast and don a life vest. Click here for the YouTube video: http://www.youtube.com/watch?v=VKR9Vk5lftc&feature=youtu.be This video outlines the importance of accurate and up-to-date marine weather forecasts before venturing out.

 

Understanding marine forecasts is critical to safe boating. Weather and wave conditions can change suddenly, catching boaters off-guard and creating life-threatening conditions. Before setting out, obtain the latest marine forecast and warning information from www.weather.gov/marine or NOAA Weather Radio. Begin listening for extended outlooks with general information for the next five days, offered in both graphical and text formats.

This brochure, How To Lock Through, instructs recreational boaters on using our navigation locks.
Willamette Falls Locks are closed to the public since November 2011. Due to concerns about the condition of the gudgeon anchors, or the equipment that helps move and stabilize the lock gates, the Portland District's dam safety officer placed the locks in a non-operational status.

Hazards to navigation

The U.S. Army Corps of Engineers and the U.S. Coast Guard have authority to remove hazards to navigation from the waterways of the United States. 
Generally, the U.S.Coast Guard is the primary agency to identify and remove a hazard to navigation; however, the U.S. Army Corps of Engineers may be asked for assistance. Either USCG or USACE may remove hazards at the owner's expense. Local port districts, city, county and state agencies may also take legal action against an owner for removing a hazard to navigation within their jurisdictions.

Authority for removal of hazards to navigation by the U.S. Army Corps of Engineers is referenced in Sections 15-20 of the River and Harbor Act of 1899.
Guidelines for coordination, removal of hazards to navigation, and cost recovery between the United States Coast Guard and the United States Army Corps of Engineers are found in the following:
