United States Coast Guard Auxlilary Flotilla 73 boating on the Columbia River
Welcome to the home page of US Coast Guard Auxiliary Flotilla 73.

Flotilla 73 serves the boating public in the Northwest Oregon and Southwest Washington areas. 
 
Our area of patrol responsibility includes the Willamette River from the Oregon City Falls to Kelly Point, and the Columbia from Bonneville Dam to St. Helens.  You will often see us underway at major maritime events, such as the  Rose Festival, Yacht Club Opening Day, Christmas Ship escort duty, Fourth of July fireworks shows in Portland and Vancouver, barge launches, “make way” patrols for commercial shipping, and marine safety/security patrols. 
 
We work closely with our active duty, reserve and civilian colleagues from U.S. Coast Guard District 13, U.S.C.G. Sector Portland and Station Portland to educate the public about boating safely, protect the environment, and keep the region's waterways safe & secure.
