1897- Construction of a 2, 204-f t-long north breakwater (Figure 265, Sec- 

 1902 tions A and B) and a 10, 200-f t-long south breakwater (Figure 265, 



Sections E, F, G, and H) was completed during this time. The north

 and 36-ft-wide (Figure 268, Section A) stone-filled timber cribs. 

 Concrete and stone superstructures were included which had crest els 

 of +13.5 ft Iwd (Figure 268, Sections A and B) . Portions of the 

 south breakwater were constructed with 36-ft-wide stone-filled timber 

 cribs (Figure 266, Section G and Figure 268, Sections F and H) . Sec- 

 tion G (Figure 266) included a concrete and stone superstructure with 

 a crest el of +15 ft Iwd. Section H (Figure 268) included a concrete 

 superstructure with an el of +14.5 ft Iwd, and Section F (Figure 268) 

 had a stone superstructure with an el of +14.5 ft Iwd and a 14-ft- 

 wide crest width sloping to the lake on the lakeside. Section E 

 (Figure 266) was a rubble-mound structure with a crest el of +14.5 ft 

 and a width of 14 ft. Slopes on the harbor side ranged from 1V:0.7H 

 to 1V:1.22H to 1V:2.5H. Armor stone on the lakeside was approxi- 

 mately 6.5 tons in weight. 



1902- Riprap was placed on the lakeside of a portion of the south break-

the breakwater was 12 ft in width with a crest el of +14.5 ft Iwd. 



Slopes on the harbor side were 1V:0.7H, and slopes on the lakeside 



ranged from 1V:1.25H to 1V:2.5H. 



1923- A stone superstructure with a concrete cap was placed on the Stony
