Maryland has 281 namedislands within its many waters and waterways, including theAtlantic Ocean; theChesapeake Bay and its many tributarytidal rivers, creeks and bays; as well as within largerwhitewater rivers like the upperPotomac.
These Islands are relatively permanent, although some are disappearing on the scale of a few centuries, likeSmith Island in the Chesapeake Bay.
There are also a number of unnamed islands in Maryland, many of which are very temporary in nature, lasting only a few years or decades, both in the tidal environment and also in Maryland's larger whitewater rivers. These come and go due to the effect of storms.
