predominantly southerly littoral drift to pass through the jetty, causing
shoaling of the inner bar and the Sand Island and Crossover Channel. The
deterioration of the jetty also forced the channel southward from 2,000 ft
north of the south jetty to along the north side of the south jetty. The
channel gradually deepened, reaching depths of -65 to -70 ft mllw and eroding
the sand foundation material from the south jetty.

of the south jetty were reconstructed, and
In 1966 4,000
of the north jetty were reconstructed during 1975 to 1976, both using

placed stone construction over the earlier randomly placed stone. The outer
5,600 ft of the south jetty and 1,200
of the north jetty are submerged, and
there are no plans to restore them to grade. The reconstructed portion of the
north jetty has been overtopped on several occasions, threatening or damaging
a major roadway that parallels a portion of the jetty.
125. The jetties were inadequate to maintain project dimensions in the
bar channel, particularly when in a deteriorated condition. Supplemental
dredging was therefore initiated in
and continued at regular intervals
until 1926. The bar required almost continual dredging from 1926 until the
jetties were reconstructed. The bar has not been dredged since 1942. A
chronology of events related to the development and repair of the harbor
structures is given in Table 37.
Kingston Harbor, Washington
126. Kingston Harbor is a locally maintained small-boat basin located
in Appletree Cove on Puget Sound at Kingston, Washington, about 10 miles
northwest of Seattle. The project authorized improvements to an existing
basin, including construction of a 1,040-ft rubble-mound breakwater and
dredging an entrance channel. The project was adopted in 1962 and constructed

Lake Crockett, Washington
127. Lake Crockett is located on Whidbey Island, Washington, along
Admiralty Bay in Puget Sound, The project includes a 6-acre mooring basin
protected by a breakwater.
128. The project was adopted in 1945, providing for a mooring basin and
an entrance channel connecting the basin to Admiralty Bay, protected by a
rubble-mound breakwater. The project was completed in 1948.
