Construction and Rehabilitation History
The town of Port Lions was established. The small-boat basin feasi-
study was authorized.
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.
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
armor rock on the crest and seaward
armor rock on the basin side. The armor rock in
sides, and Class
the secondary layer included 95 percent over 50 lb and 30 to 70 per-
cent over 600 lb. The Class
armor rock was over 400 lb, with
armor rock was 98 percent
85 percent over 1,000 lb. The Class
over 3,000 lb and 75 percent over 4,000 lb.
The harbor is illustrated in Figure 40, and an aerial photograph of
1985
the harbor is presented in Figure 41. There have been no reports of
needed repairs or rehabilitation since 1983.
