Hydrologic Unit Code Watersheds ~ 2000 for US, about the size of counties Region 02 Mid-Atlantic Region -- The drainage within the United States that ultimately discharges into: (a) the Atlantic Ocean within and between the states of New York and Virginia; (b) Long Island Sound south of the New York-Connecticut State Line; and (c) the Riviere Richelieu, a tributary of the St. Lawrence River. Includes all of Delaware and New Jersey and the District of Columbia, and parts of Connecticut, Maryland, Massachusetts, New York, Pennsylvania, Vermont, Virginia, and West Virginia. Subregion 0201 -- Richelieu: The Riviere Richelieu Basin, including Lake Champlain drainage, within the United States. New York, Vermont. Area = 7720 sq.mi. Accounting Unit 020100 -- Richelieu. New York, Vermont. Area = 7720 sq.mi. Cataloging Units 02010001 -- Lake George. New York, Vermont. Area = 1390 sq.mi. 02010002 -- Otter. Vermont. Area = 1090 sq.mi. 02010003 -- Winooski. Vermont.
