About this site

Great Diamond Island is an island in Casco Bay, Maine.

Photos taken at this site will help monitor and document changes to the sandbar area that connects Great Diamond Island to Little Diamond Island at low tide. This road is critical to providing services to both islands. Photos will help document erosion of land on Great Diamond Island and changes to the sandbar road, especially as water levels rise.

The monitoring post is accessible to Great Diamond Island residents at both high and low tide and accessible to Little Diamond residents who walk across the sandbar at low tide.

The OCT monitoring site is located on private property but close to the traveled road. We urge visitors to be respectful. You also may notice that this observation site was moved. It was no longer accessible where it was initially placed, so we adapted to this new location.
