Island Info - Little Diamond Island, Maine

Little Diamond Island is an island in Casco Bay, Maine. The island was known as 'Little Hog Island' during colonial times. It is part of the city of Portland, Maine. As of the 2000 census, the island had a year-round population of 5.

At low tide, Little Diamond Island connects to Great Diamond via a semi-submerged sandbar. This is how the City of Portland is capable of picking up the trash on both islands.

Little Diamond Island's water supply comes from the City of Portland, with the majority of the houses/cottages receiving their water through above ground pipes. The above ground pipes are turned off and emptied in the winter leaving the south end of the island with no water.
