The mouth of the Columbia River MCR jetty system is in a state of structural decay. Continued deterioration, ongoing storm activity and the continued loss of sand shoal material the foundation of each of the three MCR jetties has positioned the jetty system for a series of frequent, costly emergency repairs. Consequently, significant modifications and repairs to the MCR jetties are necessary for the continued safe entry of ships into the Columbia River navigation channel.
