at mllw, between Kodiak Island and Near Island. The project was modified in
1954 to include the small-boat basin. In 1964, the earth subsided about 5 ft
in an earthquake, causing severe damage to the basin and the breakwaters. The
breakwaters were rebuilt the same year.
38. The basin, along with a small basin named Old Harbor, provide the
only harbors-of-refuge between Cook Inlet and the Shumagin Islands. An ex-
tension to the harbor was recommended in 1976 by constructing two breakwaters
on Near Island to protect a 45-acre basin. In 1984, further study on the ex-
tension was determined to be unwarranted due to the severe decline in the
local shellfish fishery. A chronology of events related to the development
and repair of the harbor structures is given in Table 1 .

Metlakatla Harbor, Alaska
39. Annette Island is located in southeastern Alaska, 1 water miles
6
south of Ketchikan, Alaska, and 650 air miles northwest of Seattle,
Washington.
40. The original basin was adopted in 1 4 and completed in 1956. The
95
harbor included 2.18 acres protected by a
rubble-mound breakwater.
A second harbor was adopted in 1972 and completed in 1982. The new harbor
provides 5.75 acres protected by a
and a
rubble-mound
breakwater. The harbor capacities are 42 boats in the original harbor and
1 0 boats in the new harbor. A chronology of events related to the devel-

midway between Kenai and Homer, 1 0 air miles or 1 7 road miles southwest of

Anchorage. The harbor is located near the mouth of the Ninilchik River. The
harbor was authorized in 1958, including a 320-ft by 150-ft basin dredged to
ft mllw, an entrance channel, and a 410-ft-long pile jetty located 50 to
1 0 ft south of the channel entrance.

42. The harbor was completed in 1961, including a 400- by 120-ft basin
upstream and downstream of the basin. The pile jetty was de-
with rock
leted. In 1967 the harbor underwent a major rehabilitation, including con-
struction of two rock pile jetties at the mouth of the river. The harbor has
required dredging or repairs every year since completion. Dredging has aver-
aged 9,500 to 9,945 cu yd per year, and a log revetment for beach erosion
control has required annual maintenance.
