The Great Lakes
A Background

The Great Lakes are a collection of freshwater lakes located in northeastern North America, on the Canada - United States border. Consisting of Lakes Superior, Michigan, Huron, Erie, and Ontario, they form the largest group of freshwater lakes on Earth by total surface and volume.





Lake Size Max depth
Erie  9,910 sq mi / 25,655 sq km 210 ft / 64 m
Huron 23,000 sq mi / 59,565 sq km 750 ft / 229 m
Michigan 22,300 sq mi / 57,753 sq km 923 ft / 281 m
Ontario  7,340 sq mi / 19,009 sq km 802 ft / 244 m
Superior 31,700 sq mi / 82,097 sq km 1,333 ft / 406 m
Total volume=22,560 cu km (5,412 cu mi)
surface=208,610 cu km (80,545 sq mi)
21 percent of the world's surface fresh water with a combined shoreline totals almost 8,000 miles (13,000 km)

We have many other types of excellent freshwater diving as well: caverns, quarries, lakes, rivers, old docks, geological formations, a wide variety of flora and fauna, etc. All of these benefits make Ontario an amazing place for everyone to dive. Not to mention that Ontario hosts Canada's Fathom Five National Underwater Marine Park.

Ontario
A Background

The most prominent important feature of Ontario is arguably the Great Lakes.

The Great Lakes are more like freshwater inland seas than lakes found in other parts of the world. They provide an superb means of travel and trade. The ships of the Great Lakes Due to harsh weather conditions which occur from time to time, many of the ships which transported goods have foundered over the years leaving behind lots of shipwrecks for our enjoyment. In addition, there are countless smaller lakes and rivers north of the Great Lakes.

The Great Lakes basin drains into the Atlantic Ocean via the St. Lawrence River. Glaciers have shaped almost all Canadian geography. The advancing and retreating sheets of ice, kilometres thick, relentlessly gored their way over Canada and the northern U.S.A., and left scars, debris piles and remains everywhere they went. This created many interesting geologic features for divers to see under the surface.
