4. Great Bear Lake

Great Bear Lake has an area of around 31,000 square kilometers, and is the largest lake entirely in Canada (i.e. not bordering with the United States). It is located in the Boreal forests of the Northwest Territories, and crosses the Arctic Circle. Due to its northern location, the lake is covered in ice during winter months, and usually frozen from  November to July. When not frozen, though, the lake is known for being exceptionally clear. Though not highly populated, the community of Délı̨nę lives on the lake, and transport trucks cross the frozen ice to deliver supplies to various northern communities in and around the area. The lake also has large populations of northern fish such as Arctic grayling, Lake trout, Lake whitefish, Arctic char, which provide food sources for many in the local area.

5. Great Slave Lake

Great Slave Lake is actually the deepest lake in North America with an average depth of 41 meters, but a maximum depth of 614 meters. In terms of surface area, it is the fifth largest in North America. Like Great Bear Lake, it is located in the Northwest Territories of Canada. More than half of the population of the NorthWest territories live in five main communities around the lake, including in the territories’ capital, Yellowknife, and the abandoned winter camp of the Hudson's Bay Company post, Fort Reliance.The remote nature of the area meant it had a strong history of fur trade and fishing. Though the fur trade mainly died out, fishing is still prominent here, and species found in the lake include Arctic grayling, Lake trout, Northern pike, and Lake whitefish.

Lake Ontario is the smallest of the Great Lakes, by area, and measures 19,011 km2. Despite its name, it is not entirely Canadian, and borders both the province of Ontario, and the state of New York meaning it is the only Great Lake that does not border Michigan State. Lake Ontario holds strong significance both historically and practically for both Canada and the U.S. Its outflow is the St. Lawrence River, which leads into the Atlantic Ocean. This pathway to the ocean allows for trade ships, goods and transportation into Canada and the United States from overseas. Aside from goods and shipping, Lake Ontario provides fresh water to roughly 9 million people across Ontario and New York state.

9. Lake Nicaragua

Lake Nicaragua
Lake Nicaragua.

Lake Nicaragua, also known as lago Cocibolca, is a freshwater lake in Nicaragua with an average surface area of 8,264, which makes it the 9th largest in North America, and largest in Central America, despite being less than half the size of the 8th largest lake in the continent, Lake Ontario. Lake Nicaragua is also the only lake outside of the United States and Canada to rank among the top ten largest lakes in North America.

The lake is located just inland of the western coast of Nicaragua, and is unique in being the only freshwater lake containing marine animals such as bull sharks, swordfish, and tarpon, all of which can be found in the lake. Though there has been debate as to how the sharks ended up in the lake, it has been discovered that they are not trapped, but able to jump the rapids of the connected San Juan river to swim in and out of the lake when needed. Though bull sharks can be highly aggressive, the lake is still considered safe to swim in in most populated areas.

10. Lake Athabasca

Lake Athabasca clinches the number ten spot on the list with an average surface area of 7,850 square kilometers. The lake crosses two provinces, the northwest corner of Saskatchewan, and the northeast corner of Alberta, though three quarters of it lies on the Saskatchewan side of the border. The lake also sits just east of Canada’s largest National park, Wood Buffalo National Park.The lake is significant due to its fish populations, and the commercial fishing industry in the area forms the primary economy for the region. Species such as Goldeye, Lake trout, Northern pike, Walleye, Yellow perch all reside in these fresh waters. 

From the Arctic Circle to the coast of Nicaragua, these lakes make up the largest lakes in North America. They provide everything from fresh drinking water to hydro power, and fishing jobs io their local inhabitants, as well a off recreational sites and beauty to visitors from near and far.
