Construction of arrowhead breakwaters was completed at the entrance
1880
canal to Sturgeon Bay (Figure 67) during this time, The breakwaters
were each constructed 1,344 ft long. The shorewardmost portions of
each structure (Figure 68, Sections A and
were constructed of
woodpilings, and the remaining portions of the breakwaters were of
stone-filled timber crib construction. Riprap breakwater toe protec-
tion was also provided. The shoreward 762-ft lengths of each break-
water (Figure 68, Section A ) were constructed to a width of 15 ft.
From that point lakeward, the next 32-ft lengths of each structure
(Section B) were 20 ft in width; the next 100-ft lengths (Section
were 18 ft in width; the next 300-ft lengths of each structure (Sec-
tion D) were 24 ft in width; and the lakeward ends (Sections E and F,
50 ft long each) were 30 ft in width.
