project, authorized in 1956 and constructed in 1968, consists of a 550-ft 

 extension to an existing, locally-constructed breakwater to protect the harbor 

 from winter storms from the south and southwest. A chronology of events 

 related to the development and repair of the harbor structures is given in 

 Table 27. 

 Rogue River, Oregon 



89. The mouth of the Rogue River is located on the southern Oregon 

 coast, 264 mi south of the mouth of the Columbia River and 319 mi north of San 

 Francisco Bay. The town of Gold Beach, Oregon, is located at the mouth of the 

 river. 



90. The project includes two rubble-mound Jetties. The south Jetty, 

 3,400 ft long, was completed in 1959; the 3,300-ft north jetty was completed 

 in i960. The north jetty, undercut by river action and damaged during a 1964 

 flood, was rehabilitated in I966. 



91. Local interests have constructed a small-boat basin on the south 

 side of the river, protected by a breakwater. The Corps provided an entrance 

 channel and turning basin for the basin in 1972. 



92. Both jetties show sporadic localized damage but are still func- 

 tional. No repair work is planned for the near future. A chronology of 

 events related to the development and repair of the Jetty structures is given 

 in Table 28. 



Siuslaw River, Oregon 



93. The mouth of the Siuslaw River is located on the southern Oregon 

 coast 154 miles south of the mouth of the Columbia River. The town of 

 Florence, Oregon, is located about 5 miles upstream from the mouth of the 

 river. 



94. The project provides for a pair of high-tide rubble-mound Jetties 

 and a channel extending from the mouth of the river upstream to mile 16.5 near 

 Mapleton, Oregon. The project was originally authorized in I89O and revised 

 in 1891. It included a 7,500-ft north Jetty and a 5,600-ft south Jetty, 



600 ft apart at the ends. The project was suspended in 1905, at which time 

 the north jetty had been constructed to 4,090 ft, and the south Jetty had not 

 been started. 



95. The present project was authorized in 1910 and included extension 

 of the north Jetty by 3,700 ft and a 4,200-ft south Jetty, with the Jetties 

 separated by 750 ft at their ends. The Jetties were completed in 1917, at
