Date(s) Construction and Rehabilitation History 



1948- A 74-ft-long stone-filled timber crib north pier was constructed in 

 1949 1948. (Figure 75, Section G) . In 1949 the pier was rebuilt by- 

 installing steel sheet piles on each side, filling the voids with 

 gravel, and capping the structure with stone (Figure 76, Section G) . 

 The pier was 24 ft in width and had a crest el of +7.0 ft Iwd. 



1951- A 148-ft-long portion of the south breakwater (Figures 75 and 76, 

 1960 Section Fl) was repaired. Steel sheet piles were installed along 



each side of the breakwater, and 3-ft-thick precast concrete blocks 



were placed in the superstructure. 



1982 A site inspection made of the structures indicated that the north 

 pier and north breakwater were in good to excellent condition. The 

 shoreward 1,200 ft of the south breakwater was also in good condi- 

 tion; however, the lakeward portions (Sections B, F, and Fl) were in 

 need of repair. Settlement of Section B had occurred, and portions 

 of the concrete cap had deteriorated and required patchwork. Sec- 

 tions F and Fl were in fair to poor condition. Stone fill was 

 required under the concrete cap, and in some areas the cap needed 

 replacement. 



1983 Repair of the deficiencies noted during the 1982 site inspection was 

 completed. 



1986 The structures are presently in good condition.
