 Port Lions Harbor 

 Port Lions, Alaska 



Date(s) Construction and Rehabilitation History 



1965 The town of Port Lions was established. The small-boat basin feasi- 

 bility study was authorized. 



1977 The project was approved for construction by the Office of the Chief 

 of Engineers, including an undredged 12-acre basin protected by a 

 650-ft north breakwater and a 500-ft south breakwater and an un- 

 dredged 750- by 150-ft wide entrance channel. 



1981 The project was constructed, including an undredged 5-acre basin 



protected by a 600-ft main breakwater and a 170-ft stub breakwater 

 and an undredged entrance channel. A storm in November destroyed 

 most of the main breakwater. 



1983 The main breakwater was rebuilt and lengthened to 725 ft, and an 



entrance channel was dredged. The breakwater and the extension were 

 rebuilt with a core of 5- to 50-lb stone, a layer of secondary armor 

 rock and a layer of Class "A" armor rock on the crest and seaward 

 sides, and Class "B" armor rock on the basin side. The armor rock in 

 the secondary layer included 95 percent over 50 lb and 30 to 70 per- 

 cent over 600 lb. The Class "B" armor rock was over 400 lb, with 

 85 percent over 1,000 lb. The Class "A" armor rock was 98 percent 

 over 3,000 lb and 75 percent over 4,000 lb. 



1985 The harbor is illustrated in Figure 40, and an aerial photograph of 

 the harbor is presented in Figure 41. There have been no reports of 

 needed repairs or rehabilitation since 1983.
