and repair of the jetty structures is given in Table 47. 



Westhaven Cove Sraall- 

 Boat Basin, Washington 



151. 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. 



152. Breakwater A is connected to the north end of the basin and is 

 970 ft long. Breakwater B, 700 ft long, was detached and located near the end 

 of breakwater A. A closure breakwater, 260 ft long, connects the two break- 

 waters. Breakwater C, 1,550 ft long, is connected to a detached 865-ft break- 

 water at the southern end of the basin that existed before the Corps takeover 

 of the project. The stub breakwater is 200 ft 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 1939 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- 

 ology of events related to the development and repair of the harbor structures 

 is given in Table 48. 



Willapa River and Harbor and 

 Naselle Harbor, Washington 



154. 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. 



155. The project is part of the Willapa River and Harbor project 

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



26 miles of deep-draft channels which were classified "inactive" in 1977. A 

 chronology of events related to the development and repair of the harbor 

 structures is given in Table 49.
