Gun Rock and Short Point Breakwaters 



Lubec Channel, Maine 



Date(s) Construction and Rehabilitation History 



1884 Gun Rock breakwater (Figure 3) was constructed to a length of 

 approximately 250 ft. 



1956 The Gun Rock breakwater was extended 90 ft seaward, and the 385-ft 

 Short Point breakwater was constructed. The breakwaters were built 

 with a 6-ft crown width and 1V:1H side slopes using 0.5- to 6-ton 

 stones. The smaller stone sizes were used as core stone. Design 

 crown elevations were +21 and +24 ft mlw at Gun Rock and Short Point, 

 respectively. Total cost was $63,000 for placing 7,500 tons of stone 

 (approximate figures). 



1967 The breakwaters were inspected and considered to be in good condi- 

 tion. Because of an adjacent bridge abutment, the Short Point break- 

 water no longer serves a useful purpose, and no reason for future 

 maintenance exists. 



1974 The Gun Rock breakwater was visually inspected and considered to be 

 in good condition. 



1981 Visual inspection of Gun Rock breakwater indicated it was in good 

 condition. 



1984 The Gun Rock breakwater was visually inspected and considered to be
