Westhaven Cove Small-
Boat Basin, Washington
Westhaven Cove is located on Gray's Harbor on the Pacific Coast of
Washington, about 100 miles north of Portland, Oregon. The basin, referred to
as West Port Marina, is protected by three main breakwaters (breakwaters A, B,
and C), a closure breakwater, a breakwater that existed before the Corps
assumed the project, and a stub breakwater. In addition, the Corps maintains
a groin field and revetment at the tip of Point Chehalis.
Breakwater A is connected to the north end of the basin and is

970 ft long. Breakwater B, 700
long, was detached and located near the end
of breakwater A. A closure breakwater, 260 ft long, connects the two break-
long, is connected to a detached 865-ft break-
waters. Breakwater C, 1,550
water at
southern end of the basin that existed before the Corps takeover
of the project. The stub breakwater is 200
long and extends from the south
end of the marina toward the detached breakwater. All of the breakwaters are
of stone and timber composite construction.
153. Reconstruction of the south jetty at Gray's Harbor, Washington,
during 1936 to
blocked the littoral drift feeding Point Chehalis, re-
sulting in extensive erosion. A short section of the south jetty was removed
to try to restore the littoral transport, but the opening was quickly blocked
with sand. A groin field was therefore constructed on the point to trap
sediment, and a revetment was constructed to protect the shoreline. A chron-

Naselle Harbor, Washington
Nahcotta is located on the west side of Willapa Bay on the Pacific
coast of Washington, The project includes an entrance channel to a mooring
basin and a rubble-mound breakwater about 1,500 ft long. There have been no
structural problems reported since completion of the breakwater in 1958.

adopted in 1916 and modified by subsequent Acts. The project includes
