Our Bays
The Inland Bays include 3 interconnected bodies of water; Rehoboth Bay (the northern bay, in Rehoboth Beach and Dewey Beach); Indian River Bay (the largest bay), and Little Assawoman Bay, (the smallest and southernmost of the bays). It is a shallow water estuary with average depth of 4.5 ft.
In contrast to the Delaware Bay or Chesapeake Bay which are both drowned river valley estuaries, the Inland Bays are a shallow coastal lagoon system behind a narrow barrier island.
The Bays and their tributaries cover about 32 square miles and drain a landmass, called the watershed, of about 320 square miles.
