Anchor Bay is a freshwater bay forming the northern region of Lake St. Clair in the U.S. state of Michigan. It generally encompasses the waters north of a line between Huron Point (part of the Lake St. Clair Metro Park Beach, not to be confused with Port Huron) and the Middle Channel of the St. Clair River (which enters Lake St. Clair between Dickinson Island and Harsens Island). It covers over 90 square miles (230 km2) and a depth of from 1 to 11 feet (0.30 to 3.35 m), which is unusually shallow for its immense size.

Geography

The bay is about 25 miles (40 km) northeast of downtown Detroit, Michigan. It is just south of New Baltimore, Michigan and borders the townships of Harrison, Clinton, Chesterfield, Anchorville, Ira, Fair Haven, Clay, and several islands including Dickinson and Harsens. It is notable for the fact that Canadian waters lie to the south of the adjacent United States territory and make up a major portion of Lake Saint Clair.

Anchor Bay measures over 8 nautical miles (15 km; 9.2 mi) from north to south and over 9 nautical miles (17 km; 10 mi) from east to west. It is fed by the St. Clair River, which flows southwards from Lake Huron and has an extensive river delta where it enters Lake Saint Clair, the largest delta of the Great Lakes System. [1] [2] This bay is part of the Great Lakes System.

Naming

As early as 1710, the English identified the lake on their maps as Saint Clare. By the Mitchell Map in 1755, the spelling appeared as St. Clair, the form that became most widely used. [3] Some scholars believe the name honors American Revolutionary War General Arthur St. Clair, later Governor of the Northwest Territory; however, the name Lake St. Clair was in use, with its current spelling, long before St. Clair became a notable figure. The lake's name and the general's name likely influenced the namings of St. Clair County, the township of St. Clair, and the cities of St. Clair and St. Clair Shores.

The name's origin has also been confused with Patrick Sinclair, a British officer who purchased land on the St. Clair River at the outlet of the Pine River. There, in 1764, he built Fort Sinclair, in use for nearly 20 years before it was abandoned. [4]

Unlike most smaller lakes in the region—but like the Great Lakes—Lake occurs first in its name rather than at the end, reflecting its French origins.

Water quality

Anchor Bay is a part of the largest freshwater delta in the Great Lakes. Its current water quality is quite good despite past pollution incidents and a history of chemical bio-accumulation. A number of cities obtain their drinking water from or just downstream of the lake, and quality is closely monitored. [5] [6]

In the early 1970s, the Canadian and American governments closed the commercial fishery over concerns of bio-accumulation of mercury caused by the Dow Chemical Chlor-Alkali Plant in Sarnia, Ontario. Since 1949, Dow operated mercury cell plants there for the production of chlorine and other chemicals, discharging mercury into the river and contaminating the fishery. The fishery has remained closed, although studies indicate mercury levels are now well within safe ranges. [7]

Boat clubs

Many yacht clubs (boating and sailing clubs) are along the lake's shores, including:

Public beaches

Fauna

Many of North America's freshwater fish species are found in the lake throughout the seasons. Species popular with anglers include bass, bluegill, bullhead, catfish, muskellunge, northern Pike, perch, salmon, smelt, steelhead, sturgeon, trout, and walleye. Several invasive species also inhabit the lake, including zebra mussels, sea lampreys, alewives and round gobies.

Great Lakes Group of lakes in North America

The Great Lakes, also called the Great Lakes of North America or the Laurentian Great Lakes, is a series of large interconnected freshwater lakes in the mid-east region of North America that connect to the Atlantic Ocean via the Saint Lawrence River. They are Lakes Superior, Michigan, Huron, Erie, and Ontario and are in general on or near the Canada–United States border. Hydrologically, there are four lakes, because lakes Michigan and Huron join at the Straits of Mackinac. The Great Lakes Waterway enables travel by water among the lakes.

Lake Michigan One of the Great Lakes of North America

Lake Michigan is one of the five Great Lakes of North America. It is the second-largest of the Great Lakes by volume and the third-largest by surface area, after Lake Superior and Lake Huron. To the east, its basin is conjoined with that of Lake Huron through the narrow Straits of Mackinac, giving it the same surface elevation as its easterly counterpart; the two are technically a single lake.

Lake Huron One of the Great Lakes of North America

Lake Huron is one of the five Great Lakes of North America. Hydrologically, it comprises the easterly portion of Lake Michigan–Huron, having the same surface elevation as its westerly counterpart, to which it is connected by the 5-mile-wide (8.0 km), 20-fathom-deep Straits of Mackinac. 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 Huron people inhabiting the region. The Huronian glaciation was named from evidence collected from 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, and the main outlet is the St. Clair River.
