Port Clinton Harbor Jetties 



Port Clinton, Ohio 



Date(s) Construction and Rehabilitation History 



1893 Construction of parallel jetties extending lakeward from the mouth of 

 the Portage River (Figure 204) was completed. The original lengths 

 of the east and west jetties were 2,200 and 1,980 ft, respectively. 

 The jetties were constructed of woodpiling and stone. Side slopes of 

 the rubble portions of the structures were IV: IH. 



1963 Breakwater repairs were completed for a cost of $12,240. 



1973 Placement of stone on various portions of the east jetty was com- 

 pleted to repair areas that were washed out and damaged by a large 

 storm in 1972. The cost of these repairs was $128,860. 



1980 An inspection of the site indicated the structures were in very poor 

 condition with the exception of the areas that were repaired in 1973. 

 The jetties were badly deteriorated and sheet pile and additional 

 stone was recommended. It was also recommended that 850 ft of the 

 shore arm of the west jetty be deauthorized since much of it was 

 settled badly and/or buried and it was not considered necessary for 

 shore protection. This deauthorizatlon would result in a west jetty 

 length of 1,130 ft as shown in Figure 204. 



1982 Repair of damaged areas of the east jetty was completed. Damaged 

 areas were overlayered with stone similar to that used during con- 

 struction in 1973. Steel sheetpiling and a concrete cap were in- 

 stalled on the portion of the jetty adjacent to the overbank, and a 

 concrete walkway was installed on the structure originating at the 

 shoreline and extending 1,000 ft lakeward (Figure 204). The crest el 

 of the concrete cap ranged from +3 to +5 ft Iwd, and the el of the 

 walkway was +7.25 ft Iwd. 



1983- Repairs to the west jetty were completed. Armor stone was placed 



1984 along the lakeside and the crest of the existing jetty. These stones 



ranged from 0.5 to 3.5 tons. The crest el after the repairs was 



+7.3 ft Iwd. 



1986 The structures are presently considered to be in good condition. An 

 aerial view of the Port Clinton Harbor Jetties is shown in 

 Figure 205.
