Thousand Islands, Alexandria Bay

Island Nature / Park
The Thousand Islands constitute an archipelago of 1,864 islands that straddles the Canada-U.S. border in the Saint Lawrence River as it emerges from the northeast corner of Lake Ontario. They stretch for about 50mi downstream from Kingston, Ontario. The Canadian islands are in the province of Ontario, the U.S. islands in the state of New York. Canada is home to the majority of islands with just over two-thirds in Ontario.The 1,864 islands range in size from over 40sqmi to smaller islands occupied by a single residence, or uninhabited outcroppings of rocks that are only home to migratory waterfowl. To count as one of the Thousand Islands, emergent land within the river channel must have at least 1ft2 of land above water level year-round, and support at least two living trees.GeographyLarge freighters frequently ply the Saint Lawrence Seaway, but the area has so many shoals and rocks that foreign vessels must use maritime pilots to help them travel through the hazardous waterway. Under the Canadian span, a vessel just less than offshore can find itself in over of water. Similarly, rocks and shoals less than 2ft underwater can be found in the center of channels deep.Because of the great number of rocks and shoals just above or below the water's surface, it is unwise to travel the waters at night, unless one stays in the main channels and has charts, a chart plotter, or knows the area well. The water is so clear in some areas that a rocky bottom can be observed in of water. Before the advent of the zebra mussel, visibility of only 10to was usual, slightly decreasing as the years passed. Water clarity improved markedly in the mid-1990s with the arrival of zebra mussels, which feed on algae. The area has several shipwrecks, and although most of them are over underwater, some are a mere 15ft down and can be seen from the surface.
