Construction and Rehabilitation History 



Construction of a 1 ,400-ft-long rubble-mound breakwater north of the 

 river entrance and an earth fill (Figure 201) was completed. The 

 breakwater had a +6.1 ft Iwd crest el, an 8-ft-wide crest width, and 

 1-V:1.5-H side slopes (Figure 201). Cover stone ranged from 1,000 lb 

 to 1 ton. 



1986 There is no record of breakwater maintenance, and the structure 



presently is in good condition. An aerial photograph of the Clinton 

 River breakwater is shown in Figure 202.
