Building Strong® at the Coos Bay
Coos Bay is on the Oregon coast 200 miles south of mouth of Columbia River and 445 miles north of San Francisco Bay.
Coos Bay is about 13 miles long and 1 mile wide, with an area at high tide of about 15 square miles. The Corps maintains two jetties at the entrance: the south jetty, completed in 1928, and the north jetty, completed in 1929.
The original authorization allowed the Corps to maintain the entrance channel at 45 feet deep and 700 feet wide. A modification was authorized in the fiscal year 1996 Energy and Water Development Appropriations Act, Public Law 104-46, which provided for deepening the channel by 2 feet to 47 feet from the entrance to Guano Rock at river mile 1, and to 37 feet from river mile 1 to 15. Public Law 104-46 also provided for deepening by two feet and expanding the turning basin at river mile 12 by 100 feet from 800 by 1,000 feet to 900 by 1,000 feet.
