included an inner basin 375 by 125 by 5 ft deep at mllw, and an entrance 

 channel 5 ft deep at mllw by 30 ft wide. An expansion to the project was 

 authorized in 1945, including deepening the channel and enlarging the basin, 

 constructing a l60-ft breakwater outside the north entrance to the bay, and 

 constructing a retaining wall along the easterly side of the basin. The 

 expansion was completed around 1950. In I960, another expansion was autho- 

 rized, including constructing a second breakwater on the northern entrance to 

 the bay and widening the entrance channel. 



83. The project is in good condition at this time. There is no record 

 of either breakwater requiring maintenance since its construction. A chronol- 

 ogy of events related to the development and repair of the harbor structures 

 is given in Table 25. 



Nehalem River, Oregon 



84. Nehalem Bay is located at the mouth of the Nehalem River, about 

 40 miles south of the mouth of the Columbia River, on the Pacific coast of 

 Oregon. In the latter half of the 1800' s, local interests repeatedly peti- 

 tioned the Corps for construction of Jetties to maintain a channel across the 

 bar. Unfavorable survey reports in 1875, 1884, and 1886 prevented the work 

 from being started. 



85. In 1890, the construction of two high-tide Jetties at the mouth of 

 the river was authorized at an estimated cost of $326,000. In 1891 the esti- 

 mated cost was increased to $712,000. The project was terminated in 1898 

 without any construction being started. 



86. The existing project was authorized in 1912, including two converg- 

 ing, high-tide, rubble-mound Jetties, 700 ft apart at the outer ends, with the 

 north and south Jetties being 3,850 and 4,950 ft long, respectively. The 

 south Jetty included work begun by local interests in 1910, and local inter- 

 ests would pay one-half the costs of construction of the two Jetties. The 

 south Jetty was completed in 1915; the north Jetty was completed in 1918. 



87. No repairs were made to the Jetties, and the project was classified 

 inactive in 1934. In 1981, both Jetties were given major rehabilitation and 

 are currently in good condition. A chronology of events related to the 

 development and repair of the jetty structures is given in Table 26. 



Port Orford, Oregon 



88. Port Orford is located on the southern Oregon coast, 250 miles 

 south of the Columbia River and 390 miles north of San Francisco Bay. The
