Coos Bay to stabilize the channel and that sand fences be constructed to pre- 

 vent windblown sand from extending the spit. Instead, a spur Jetty was 

 authorized in 1879. In 1889, a board of engineers recommended that work on 

 the spur Jetty be halted and that two parallel Jetties be constructed at the 

 mouth of the bay. 



75. The north Jetty was constructed to a 9,600-ft length between 1891 

 and 1895 and restored between 1923 and 1929. The south Jetty was constructed 

 in 1929 and 1930. 



76. A small-boat mooring basin in South Slough at Charleston was 

 authorized in 1948. The project included a 2,100-ft breakwater. The project 

 was constructed during 1956 to 1957 and then expanded by local interests in 

 1966. A chronology of events related to the development and repair of the 

 Jetty and harbor structures is given in Table 23. 



Coquille River, Oregon 



77. The mouth of the Coquille River is located on the southern Oregon 

 coast about 225 miles south of the mouth of the Columbia River and 420 miles 

 north of San Francisco Bay. The town of Bandon, Oregon, is located at the 

 mouth of the river. 



78. The project includes a 3,450-ft north Jetty and a 2,700-ft south 

 Jetty, both of rubble-mound construction, authorized in 1880 and completed in, 

 1907. 



79. The outer 1,600 ft of the north Jetty was rerocked and capped with 

 concrete in 1942 and repaired again in 1956. A 750-ft shoreward extension was 

 added to the east end of the north Jetty in 1951. The outer 450 ft of the 

 south Jetty was repaired in 1954. 



80. Currently, the north Jetty head is in need of repair but is still 

 functional. The south jetty is in good shape. A chronology of events related 

 to the development and repair of the jetty structures is given in Table 24. 

 Depoe Bay, Oregon 



81. Depoe Bay is a small, rock-bound tidal basin on the Oregon Coast 

 about 100 mi south of the Columbia River, measuring roughly 500 ft by 1,000 ft 

 at high tide. The entrance to the bay is a narrow opening between rocky 

 bluffs that connects the bay to an outer cove and the open sea. The entrance 

 is about 300 ft long by as little as 20 ft wide at project depths and 100 ft 

 wide at high waterline. 



82. The original project, authorized in 1937 and completed in 1939,
