Lake Ontario is one of the five Great Lakes of North America, and is located mainly in the province of Ontario in Canada, with some of its northern shoreline located in the US state of New York. It is the fourteenth largest lake in the world, with a surface area of 7,340 square miles and a maximum depth of 802 feet. The deepest point in this vast body of freshwater is located in the northeastern portion of the lake, near the small Canadian town of Cobourg, Ontario.
This spot, known as the “Cobourg Hole”, is situated at a latitude of 43° 59' N and a longitude of 78° 19' W. It was first discovered in 1883 by Captain J.P. Tully, commander of the Canadian government research vessel, the Bayfield. Captain Tully and his crew used a sounding line to measure the lake’s depths, and recorded a depth of 802 feet at the Cobourg Hole. This measurement was later confirmed by the United States Geological Survey in 1884.
The Cobourg Hole is located at the center of a deep depression in the lake bed that is approximately 12 miles in diameter. This depression forms a near-perfect circle and is surrounded by steep, rocky walls that rise up from the lake bottom. The walls of the depression are believed to have been created by a meteor strike that occurred approximately 11,000 years ago.
The Cobourg Hole is a very unique and fascinating part of Lake Ontario. It is a place of great beauty, with its steep walls, dark depths, and vibrant aquatic life. It is home to many species of fish and other aquatic creatures, and provides a habitat for them to thrive. The Hole is also a popular fishing spot, as the deep waters are home to some of the larger and more sought-after species of fish.
Lake Ontario is a vast body of freshwater, and the Cobourg Hole is its deepest point. At a depth of 802 feet, it is a testament to the power of nature and the enduring beauty of the Great Lakes.
