Jefferson County is a county in the U.S. state of New York. As of the 2010 census, the population was 116,229. Its county seat is Watertown. The county is named after Thomas Jefferson, third President of the United States of America. It is adjacent to Lake Ontario, southeast from the Canada-US border of Ontario.
When counties were established in the Province of New York in 1683, the present Jefferson County was part of Albany County. This was an enormous county, including the northern part of New York State as well as all of the present State of Vermont and, in theory, extending westward to the Pacific Ocean. This county was reduced in size on July 3, 1766 by the creation of Cumberland County, and further on March 16, 1770 by the creation of Gloucester County, both containing territory now in Vermont.
On March 12, 1772, what was left of Albany County was split into three parts, one remaining under the name Albany County. One of the other pieces, Tryon County, contained the western portion (and thus, since no western boundary was specified, theoretically still extended west to the Pacific). The eastern boundary of Tryon County was approximately 5 miles (8.0 km) west of the present city of Schenectady, and the county included the western part of the Adirondack Mountains and the area west of the West Branch of the Delaware River. The area then designated as Tryon County now includes 37 counties of New York State. The county was named for William Tryon, colonial governor of New York.
In the years subsequent to 1776, most of the Loyalists in Tryon County fled to Canada. In 1784, following the peace treaty that ended the American Revolutionary War, the name of Tryon County was changed to Montgomery County to honor the general, Richard Montgomery, who had captured several places in Canada and died attempting to capture the city of Quebec, replacing the name of the hated British governor.
In 1789, the size of Montgomery County was reduced by the splitting off of Ontario County from Montgomery. The actual area split off from Montgomery County was much larger than the present county, also including the present Allegany, Cattaraugus, Chautauqua, Erie, Genesee, Livingston, Monroe, Niagara, Orleans, Steuben, Wyoming, Yates, and parts of Schuyler and Wayne Counties.
Jefferson County is part of Macomb's Purchase of 1791.
In 1791, Herkimer County was one of three counties split off from Montgomery (the other two being Otsego, and Tioga County). This was much larger than the present county, however, and was reduced by a number of subsequent splits. The first one of these, in 1794, produced Onondaga County. This county was larger than the current Onondaga County, including the present Cayuga and Cortland Counties, and part of Oswego County.
According to the U.S. Census Bureau, the county has a total area of 1,857 square miles (4,810 km2), of which 1,269 square miles (3,290 km2) is land and 589 square miles (1,530 km2) (32%) is water. It is the fourth-largest county in New York by total area.
Jefferson County is located in the northern lobe of New York State, adjacent to the area where the Saint Lawrence River exits Lake Ontario. It is northeast of Syracuse, and northwest of Utica. The county is at the international border with Canada.
The Black River, which empties into Lake Ontario, is an important waterway in the county. Part of the Tug Hill Plateau is in the southern part of the county. The county contains part of the Thousand Islands in the St. Lawrence River, including such large islands as Carleton Island, Grindstone Island, and Wellesley Island.
