Date(s) Construction and Rehabilitation History 



1900 Construction of the 796-ft-long outer portion of the north breakwater 

 (Figure 88, Section F) was completed. The breakwater was a stone- 

 filled timber crib structure (Figure 89, Section F) . It was 30 ft 

 wide, and riprap toe protection was placed on each side. 



1912- Construction of the 1,844-ft shoreward portion of the north break- 

 1913 water was completed during this time (Figure 88, Sections A, A', B, 

 B', C, D, and E) . The shoreward 800 ft of the structure (Figures 89 

 and 90, Sections A, A', B, and B') v/ere constructed with woodpilings 

 driven from 11 to 14 ft apart and stone filled. The breakwater was 

 capped with a stone and concrete superstructure installed at an el of 

 +7.1 ft Iwd. Riprap toe protection was placed on both sides of the 

 breakwater. The adjacent 1,044 ft of breakwater extending lakeward 

 (Figure 89, Sections C, D, and E) was constructed of a stone-filled 

 concrete structure built on wood piles. The crest el of the break- 

 water was +7.1 ft Iwd, and the crest width ranged from 15 to 20 ft. 

 Riprap toe protection also was installed on both sides of the 

 breakwater. 



1917- Construction of the 1 ,512-f t-long lakeward portion of the south 

 1919 breakwater (Figure 88, Sections H, I, and J) was completed during 



this period. The breakwater consisted of a concrete superstructure 

 built on stone. The superstructure was either sand or stone filled 

 (Figure 89, Sections H, I, and J). The crest el of the structure was 

 +7.1 ft Iwd, and it had a 10-ft crest width. The outer portion of 

 the structure (Section J) was covered with riprap ranging from 6 to 

 16 tons (9-ton average) to an el of +4 ft Iwd. The slope of the rip- 

 rap was 1V:1.5H. 



1924 Construction of the shoreward 1, 104-f t-long portion of the south 

 breakwater (Figure 88, Sections B and G) and the south pier (Sec- 

 tion M) was completed. The breakwater was constructed with a stone- 

 filled concrete superstructure built on woodpilings (Figure 89, 

 Sections B and G) . The pilings were 14 ft (Section B) or 17 ft (Sec- 

 tion G) apart. Riprap toe protection was included on both sides of 

 the breakwater. The north pier also consisted of a stone-filled con- 

 crete superstructure built on woodpilings that were spaced 15.5 ft 

 apart (Figure 89, Section M) . The crest el of both the breakwater 

 and pier built during this time was +7.1 ft Iwd. 



1925 The lakeward portion of the north breakwater (Figure 88, Section F) 

 was capped with a concrete superstructure. The crest el of the 

 structure was +7.1 ft Iwd (Figure 88, Section F) .
