The U.S. Army Corps of Engineers’ Portland District has just released this very interesting video named Dams et al Episode 51 – Depoe Bay Dredging.
Regular dredging, which happens every eight to 10 years depending on funding, keeps the boat basin clear (the boat basin catches sediment coming down the river and acts like “grease trap”).
The Depoe Bay federal project is a boat basin located in a small inlet off the Pacific Ocean and a check dam on South Depoe Bay Creek, in Depoe Bay, Lincoln County, Ore.
The harbor has 85,000 pounds in fish landings valued at $72,323 (2010) per year, 16,000 commercial and 15,000 recreational crossings per year, is home to a U.S. Coast Guard Station and is a critical harbor of refuge.
