the bay and widening the entrance channel.

40 miles south of the mouth of the Columbia River, on the Pacific coast of
local interests repeatedly peti-

bar. Unfavorable survey reports in 1875, 1884, and 1886 prevented the work
from being started.
85. In
the construction of two high-tide jetties at the mouth of
the river was authorized at an estimated cost of 6,000. In 1891 the esti-
cost was increased to 2,000. 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
apart at the outer ends, with the
north and south jetties being 3,850 and 4,950
long, respectively.
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

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.
