Lake Huron
Lake Huron (/ˈhjʊərɒn, -ən/ HURE-on, -ən) is one of the five Great Lakes of North America. It is shared on the north and east by the Canadian province of Ontario and on the south and west by the U.S. state of Michigan. The name of the lake is derived from early French explorers who named it for the indigenous people they knew as Huron (Wyandot) inhabiting the region. Hydrologically, Lake Huron comprises the eastern portion of Lake Michigan–Huron, having the same surface elevation as Lake Michigan, to which it is connected by the 5-mile-wide (8.0 km), 20-fathom-deep (120 ft; 37 m) Straits of Mackinac. Combined, Lake Michigan–Huron is the largest freshwater lake by area in the world. The Huronian glaciation was named from evidence collected from the Lake Huron region. The northern parts of the lake include the North Channel and Georgian Bay. Saginaw Bay is located in the southwest corner of the lake. The main inlet is the St. Marys River from Lake Superior, and the main outlet is through the St. Clair River toward Lake Erie. Lake Huron has a fairly large drainage basin covering parts of Michigan and Ontario. Water flows through Lake Huron faster than the other Great Lakes with a retention time of only 22 years.
By surface area, Lake Huron is the second-largest of the Great Lakes, with a surface area of 23,007 square miles (59,590 km2)—of which 9,103 square miles (23,580 km2) lies in Michigan and 13,904 square miles (36,010 km2) lies in Ontario—making it the third-largest fresh water lake on Earth (or the fourth-largest lake, if the Caspian Sea is counted as a lake). By volume however, Lake Huron is only the third largest of the Great Lakes, being surpassed by Lake Michigan and Lake Superior. When measured at the low water datum, the lake contains a volume of 850 cubic miles (3,500 km3) and a shoreline length (including islands) of 3,827 mi (6,159 km).
The surface of Lake Huron is 577 feet (176 m) above sea level. The lake's average depth is 32 fathoms 3 feet (195 ft; 59 m), while the maximum recorded (by sonar) depth is 125 fathoms (750 ft; 229 m). It has a length of 206 statute miles (332 km; 179 nmi) and a greatest breadth of 183 statute miles (295 km; 159 nmi). A large bay that protrudes northeast from Lake Huron into Ontario, Canada, is called Georgian Bay. A notable feature of the lake is Manitoulin Island, which separates the North Channel and Georgian Bay from Lake Huron's main body of water. It is the world's largest lake island. A smaller bay that protrudes southwest from Lake Huron into Michigan is called Saginaw Bay.
Cities with over 10,000 people on Lake Huron include Sarnia, the largest city on Lake Huron, and Saugeen Shores in Canada and Bay City, Port Huron, and Alpena in the United States. Major centres on Georgian Bay include Owen Sound, Wasaga Beach, Collingwood, Midland, Penetanguishene, Port Severn and Parry Sound.
Historic high water The lake fluctuates from month to month with the highest lake levels in October and November. The normal high-water mark is 2.00 feet (0.61 m) above datum (577.5 ft or 176.0 m). In the summer of 1986, Lakes Michigan and Huron reached their then highest level at 5.92 feet (1.80 m) above datum. The high-water records were broken for several months in a row in 2020.
Historic low water Lake levels tend to be the lowest in winter. The normal low-water mark is 1.00 foot (30 cm) below datum (577.5 ft or 176.0 m). In the winter of 1964, Lakes Michigan and Huron reached their then lowest level at 1.38 feet (42 cm) below datum. As with the high-water records, monthly low-water records were set each month from February 1964 through January 1965. During this twelve-month period, water levels ranged from 1.38 to 0.71 feet (42–22 cm) below Chart Datum. The all-time low-water mark was eclipsed in January 2013.
Counting its 30,000 islands, Lake Huron has the largest shore line length of any of the Great Lakes. It is separated from Lake Michigan, which lies at the same level, by the 5-mile-wide (8.0 km), 20-fathom-deep (120 ft; 37 m) Straits of Mackinac, making them hydrologically the same body of water (sometimes called Lake Michigan-Huron and sometimes described as two 'lobes of the same lake'). Aggregated, Lake Huron-Michigan, at 45,300 square miles (117,000 km2), "is technically the world's largest freshwater lake". Lake Superior, at 21 feet higher elevation, drains into the St. Marys River which then flows into Lake Huron. The water then flows south to the St. Clair River, at Port Huron, Michigan, and Sarnia, Ontario. The Great Lakes Waterway continues thence to Lake St. Clair; the Detroit River and Detroit, Michigan; into Lake Erie and thence – via Lake Ontario and the St. Lawrence River – to the Atlantic Ocean.
Like the other Great Lakes, it was formed by melting ice as the continental glaciers retreated toward the end of the last ice age. Before this, Lake Huron was a low-lying depression through which flowed the now-buried Laurentian and Huronian Rivers; the lake bed was criss-crossed by a large network of tributaries to these ancient waterways, with many of the old channels still evident on bathymetric maps.
