NEW HAVEN 



The New Haven disposal site (Figure H-l ) is located approximately 5 nautical 

 miles south of the entrance to New Haven harbor. The site covers a bottom 

 composed of soft silts that slope gently and smoothly to the s/outh throughout 

 the study area. 



Between October, 1973, and March, 1977 1.5 million cubic yards of material 

 were dumped at this site from dredging of New Haven harbor. These spoils formed 

 a symmetrical mound in the center of the disposal site. Subsequent to comple- 

 tion of the New Haven project, additional small volumes of spoil have been 

 dumped at a buoyed point southwest of the original site. 



Bathymetry 



Navigation for surveys in the vicinity of the New Haven disposal site is 

 provided by trisponder stations at the Old New Haven Lighthouse and Stratford 

 Point Lighthouse. 



Two surveys have been made at the New Haven site since the inception of 

 the DAMOS program, the first on February 4, 1978, (Figure H-2(.a-j)) and the 

 second on July 28, 1978 (Figure H-3(a-k)). Both of these surveys showed the 

 conical shaped spoil pile with a minimum depth of 15-15.5 meters located approxi- 

 mately in the center of the disposal area. 



Southwest of this mound a slight rise in the bottom can be seen, particu- 

 larly on Lane 18 (Figures H-2 f and H-3 f), that is located just west of the 

 present position of the disposal buoy. This rise is the only topographic ex- 

 pression of spoils that have been dumped in this area since the conclusion of 

 the New Haven project.
