The St. Lawrence River is one of the longest rivers in North
America. And, is the outflow for the entire Great Lakes system.
The Great Lakes hold nearly 20% of the world's fresh water. The
River flows 744 miles from Lake Ontario into the world's largest
estuary, the Gulf of St. Lawrence. Only 114 miles of the River
are located in New York State. The River is 250 feet at its
deepest point. Flowing through both Canadian and US lands, the
St. Lawrence River is a bi-national waterway, providing drinking
water to local municipalities on both sides of the River and a
vital tourism-based economy to local towns. The St. Lawrence
River has a discharge rate of 347, 849 cubic feet of water per
second. The Upper St. Lawrence is home to the Thousand Islands
region. There are exactly 1,864. To be counted as an island, the
piece of land must be surrounded by water, above water all year
