1868- Construction of the south pier (Figures 122, 123 and 124, Sections I 

 1879 and J) and a portion of the north pier (Figure 123, Section D) was 

 completed at the site (Figure 122) during this period of time. The 

 north pier (Section D) consisted of woodpilings driven about 24 ft 

 apart and filled with earth and stone, while the south pier (Sec- 

 tions I and J) involved a 20-ft-wide, stone-filled timber crib 

 structure. 



1875- Construction of the lakeward end of the north pier (Figure 123, 

 1876 Section C) was completed during this period. The pier consisted of a 

 20-ft-wide stone-filled timber crib structure. 



1906- Construction of the north and south arrowhead breakwater arms 

 1909 (Figure 123, Sections Al , A and B) was completed at the site (Fig- 

 ure 122) . The lakeward portions (Sections Al and A) were constructed 

 with 30-ft-wide stone-filled timber cribs, while the shoreward 

 portions of the breakwater (Section B) were built with 24-ft-wide 

 stone-filled timber cribs. 



1908- Construction of the breakwater pier connections (Figure 123, 

 1909 Section Q) was completed during this period. They consisted of wood- 

 pilings driven 12 ft apart and filled with stone. The el was +2.0 ft 

 Iwd. Rubble was placed on each side of the structure to the +2 ft 

 Iwd crest el and extended down on a slope of 1V:1.5H. 



1929 The north pier (Figure 123, Sections C and D) was capped with a con- 

 crete and stone superstructure. The el of the lakeward end of the 

 pier (Section C) was +7.1 ft Iwd, and the shoreward end (Section D) 

 was installed at a crest el of +6.1 ft Iwd. 



1932- The south pier (Figures 123 and 124, Sections I and J) and both 

 1933 breakwaters (Figure 123, Sections Al , A, and B) were capped with 

 stone and concrete superstructures during this time. The south 

 pier and both breakwaters were constructed to els of +7.1 ft Iwd. 



1958 The north pier (Figure 123, Sections C and D) was repaired. Steel 

 sheetpiling was installed on each side of the structure, and the 

 voids were filled with stone and capped with concrete. The width of 

 the lakeward portion (Section C) was 32 ft, and that of the shore- 

 ward portion (Section D) was 33.8 ft. 



1963- Rehabilitation of the lakeward heads of the breakwaters (Figure 123,
