There are wells or reservoir of water in the place and they were created for the purpose of flood control, hydroelectricity and water supply. Another amazing thing about Maryland is that these bodies of water that were created as recreational centers are considered as lake.
Maryland has this distinct characteristic among the states of America because of the absence of lakes.
