Inlet closed 



1893-1933 



Osborne (1970) stated Shinnecock Inlet closed this period. 

 1889-1890 USC&GS charts provide evidence of different 

 inlets into Shinnecock Bay, all of which closed by 1891 . 

 One of the former openings was opposite Shinnecock 

 Neck. Another was slightly west of Ponquogue Point. Two 

 others were east and west of Gull Island, opposite East 

 Quogue. 1903 and 1904 USGS surveys (Sag Harbor 

 Quadrangle) showed no inlets into either Moriches or 

 Shinnecock Bays.

Landfall around Moriches, caused severe damage.

Inlet cut 



1896 



As part of Shinnecock and Peconic canal project, channel 

 30 ft wide, 6 ft deep cut through the barrier island dunes 

 with the purpose of increased flushing of Shinnecock Bay to 

 relieve stagnant conditions. Local inhabitants donated 

 services. Dunes said to be 20-30 ft high. "...It proved a 

 failure, the waves quickly forming the dunes again, so that 

 few traces of the channel now remain."

Hurricane 



Sep 21, 1938 



The Great New England Hurricane, one of the most 

 devastating storms in New England history, caused 

 massive washovers all along south shore. Clowes (1939) 

 described four inlets opening to Shinnecock Bay: 



1 . Near Warner's Islands, 0.5 miles east of 

 Ponquogue Point, 40.5 miles east of Fire Island 

 lighthouse. Closed 1938? 



2. Opposite Cormorant Point, 41.6 miles east of 

 lighthouse. By 1939, over 700 ft wide. Still open. 



3. Opposite Shinnecock Hills, 43.3 miles east of 

 lighthouse. Closed 1938? 



4. Opposite Shinnecock Indian Reservation, 

 44.2 miles east of lighthouse. Closed 1938?
