Construction and Rehabilitation History 
Inspections during 1970-1971 showed that some 10 to 20 cover stones 
from the top layer on the slope around each jetty head had been dis- 
placed. Also, near the landward end of the north jetty, on its 
channel side, several cover stones had shifted down the slope. In 
1972 repairs were made to the jetties by resetting existing cover 
stone and placing additional cover stone at these sections and 
possibly others. No other details are available. 
An inspection showed that the north and south jetty heads required 
resetting of about 15 and 40 cover stones, respectively. Also three 
sections near the landward channel side of the south jetty showed 
some slippage of the cover layer, exposing the underlying core stone. 
The remaining jetty sections were considered to be in good condition. 
The jetties were inspected and considered to be in good condition 
except for 15 to 20 displaced cover stones at the head of each jetty.
