with a crest height of +16 ft mllw, and a 72.8-acre small-boat basin behind 

 the breakwater, A chronology of events related to the development and repair

 Swinomish Channel. Washington 



146. Swinomish Channel is a dredged inland tidal waterway— 100 ft wide, 

 -12 ft mllw deep, and 11 miles long--located in the northwestern part of the 

 state of Washington about 60 miles north of Seattle. It connects the deep 

 waters of Saratoga Passage and Padilla Bay and separates Fidalgo Island from 

 the mainland. The project includes dikes along the waterway to protect 

 farmland and three jetties at the southern end of the channel. 



147. The project was adopted in 1892. The jetties include a rubble- 

 mound and timber pile north jetty extending west from "Hole in the Wall," a 

 rubble-mound south jetty extending west from Goat Island, and a rubble-mound 

 jetty connecting Goat Island to McGlinn Island. The north jetty was con- 

 structed in 1893 and reconstructed in 1900. The south jetty was constructed 

 in 1908 and rehabilitated and extended in 1973. The Goat-McGlinn Island jetty 

 was completed in 1938 and rehabilitated in 1940, 1946, and 1963. 



148. The rehabilitations were required because of settlement due to 

 foundation problems. At the present time, the south jetty and the Goat- 

 McGlinn Island jetty appear to be in good condition, while the north jetty 

 shows obvious deterioration. A chronology of events related to the develop- 

 ment and repair of the jetty structures is given in Table 46. 



Waterway Connecting Port Townsend 

 and Oak Bay, Washington 



149. Port Townsend is located on the northern Washington coast along 

 the Strait of Juan de Fuca. The Oak Bay Canal connects Port Townsend Bay and 

 Oak Bay. The project includes two jetties at the Oak Bay end of the canal, 

 the west jetty being 550 ft long and the east jetty being 600 ft long, and 

 2,100 ft of bulkheads on the west side of the canal. The jetties were con- 

 structed of brush, pile, and stone; the bulkheads were constructed of brush, 

 pile, and timber. 



150. The project was adopted in 1913 and completed in 1916. The east 

 jetty was rehabilitated in 1937; the west jetty was rehabilitated in 1961. 

 Very little information on the project is available. Currently, the west 

 jetty is in good condition, while the east jetty shows some deterioration but 

 is stable and functional. A chronology of events related to the development
