Saco Bay

Saco Bay is approximately 10 mi (16 km) wide, running from the Fletcher Neck (the Biddeford Pool peninsula) and the mouth of the Saco River in York County north to the Scarborough River and Prouts Neck in Scarborough, Cumberland County, Maine,[1] approximately 13 mi (19 km) southwest of Portland.

Prior to its closure, the Pine Point region of Scarborough was a barrier island, the only one in Maine.

[2] Behind Pine Point is the state run wildlife management area for Scarborough Marsh.

The marsh is located within 1.5 miles (2.4 km) of two nationally significant seabird nesting islands.

Stratton Island in the bay is a wildlife sanctuary owned and run by the National Audubon Society where multiple species of terns nest.

[5] The United States Army Corps of Engineers (USACOE) initially thought that the beach sand was coming from an underwater glacial deposit.

About 1960 another jetty was built on the south (Pine Point) side of the mouth of the Scarborough River to protect it from sand.
