swamps and furnishes no material to the shore. It has been proposed 

 as a site for a small- boat harbor. 



Lake Ontario is about 190 miles long and 50 miles wide . The mean 

 lake level for the months of March to December is about 2 feet above the 

 established low water datum. The highest lake stage and the highest 

 monthly mean recorded at Oswego, New York, are respectively about 6. 2 

 and 5.3 feet above low water datum. Of winds which generate waves 

 affecting the area, those from the west and east have the greatest fetch, 

 about 90 miles. However, the wind movement and duration from the west 

 and northwest considerably exceed those from the east and northeast, 

 consequently, waves which cause the greatest movement of beach material 

 are those from the west and northwest. During severe storms, which 

 occur with a frequency of about once a year, waves may range up to 12 

 feet in height in deep water, but ordinarily waves of this height would 

 break before reaching shore structures. 



The Division and District Engineers and the Beach Erosion Board 

 concluded that the most suitable plans to provide the beach areas and 

 the protection for remaining areas of Hamlin Beach State Park cnnsist 

 of: 



a. For the westerly beach area, construction of four new 

 groins j modification of three existing groins, grading the bluffs, and 

 placement of approximately 217,000 cubic yards of sand fill; 



b. For the central beach area, construction of three new groins 

 modification of one existing groin, placement of approximately 123,000 

 cubic yards of sand fill, and construction of approximately 5>00 feet of 

 stone and concrete revetment; 



c. For the easterly beach area, construction of three new 

 groins, placement of approximately 51,000 cubic yards of sand fill, and 

 construction of approximately 2,600 feet of stone revetment. 



They found that the restoration and protection of the westerly beach 

 at Hamlin Beach State Park were warranted by evaluated benefits, and that 

 Federal participation in the first cost thereof is justified. They 

 recommended adoption of a project by the United States authorizing 

 Federal participation, subject to certain conditions, in an amount equal 

 to one -third of the first cost of the plan for the restoration and pro- 

 tection of the westerly beach area. They further recommended that the 

 State of Mew York consider adopting the foregoing plans for the central 

 and east beach areas and that no Federal project be adopted at this time 

 for those areas, but that further consideration be given to the advisa- 

 bility of Federal participation in such a project if requested by the 

 cooperating agency at such time as plans for park development are further 

 advanced and the benefits are determinable. 



The Chief of Engineers concurred in the views and recommendations 

 of the Beach Erosion Board.
