Oconto Harbor Pier 



Oconto, Wisconsin 



Date(s) Construction and Rehabilitation History 



1883 A 2,077-ft-long south pier was completed as a Federal project (Fig- 

 ure 65, Sections B-E) . The structure consisted of woodpilings filled 

 with sand and gravel (Figure 66, Sections B-E). A rubble-mound north 

 pier was built by local interests. 



1957 Construction of the 67-ft-long lakeward end of the south pier was 



completed (Figure 65, Section A). The extension consisted of 30.5-ft 

 diameter cellular steel sheet-pile structures. The cells were filled 

 with gravel and stone and had crest els of +8.5 Iwd. The lakeward 

 cell was capped with concrete, and the adjacent cell was capped with 

 3- to 5-ton capstone (Figure 66, Section A). 



1974- The original 2,077-ft-long pier was reconstructed. Ruins of the 

 1975 existing structure were capped with stone. The 227-ft-long lakeward 

 portion of the original structure (Figure 65, Section B) consisted of 

 a rubble-mound structure with a crest el of +10 ft Iwd and a width of 

 9 ft. Side slopes were installed at 1V:1.5H (Figure 66, Section B) . 

 The remaining portion of the existing breakwater (Figure 65, Sec- 

 tions C-E) consisted of a rubble-mound structure with a crest el of 

 +8 ft Iwd and a width of 7 ft. Stone ranging from 400 to 1,000 lb 

 was used as armor, and side slopes of 1V:1.5H (Figure 66, Sec- 

 tions C-E) were constructed. 



1986 The structure is considered to presently be in good condition.
