Small amounts of water are also diverted into the lake from two places otherwise outside of the watershed—Long Lac and Ogoki—in order to accentuate hydroelectric power generation at Sault Sainte Marie, Michigan, and Niagara Falls. [30] Normally, bacteria decaying a sunken body will bloat it with gas, causing it to float to the surface after a few days. [26] Warmer temperatures could lead to more snow in the lake effect snow belts along the shores of the lake, especially in the Upper Peninsula of Michigan. SS Edmund Fitzgerald was the latest ship to sink in Lake Superior, 15 nautical miles (28 km; 17 mi) from Whitefish Point in a storm on November 10, 1975.

Lake Superior has a surface area of 31,700 square miles (82,103 km2),[7] which is approximately the size of South Carolina or Austria. Use the arrows to raise and lower water levels and see how these changes might impact shoreline position and water depth in the Great Lakes.

[22], Historic high water Lake Superior drains into Lake Huron via the St. Marys River. Nautical navigation features include advanced instrumentation to gather wind speed direction, water temperature, water depth, and accurate GPS with AIS receivers(using NMEA over TCP/UDP). It is shared by the Canadian province of Ontario to the north, the U.S. state of Minnesota to the west, and Wisconsin and the Upper Peninsula of Michigan to the south. In 1918 the last warships to sink in the Great Lakes, French minesweepers Inkerman and Cerisoles, vanished in a Lake Superior storm, perhaps upon striking the uncharted danger of the Superior Shoal in an otherwise deep part of the lake. Subsequently, iron was extracted from many parts of the Lake Superior district, including the Marquette Range in Michigan and the Mesabi Range in Minnesota. In place of the present eastern lower Great Lakes (Erie and Ontario), a scarp-and-vale topography existed, with the high front of the Niagara limestone scarp separating vales of shale to the west and east.….

The main source of elevation consists of topobathy lidar from the U.S. Army Corps of Engineers. [48], As for other Great Lakes fish, populations have also been affected by the accidental or intentional introduction of foreign species such as the sea lamprey and Eurasian ruffe. Lake Michigan is the only lake that is not shared by both countries as it lies entirely within the borders of the United States. The basin accounts for about 25% of agricultural production in Canada and 7% in the United States while serving 10% of the American population and 30% of the Canadian population. Today, tourism is another significant industry: the sparsely populated Lake Superior country, with its rugged shorelines and wilderness, attracts vacationers and adventurers. In addition, many fish species have been either intentionally or accidentally introduced to Lake Superior: Atlantic salmon, brown trout, carp, chinook salmon, coho salmon, freshwater drum, pink salmon, rainbow smelt, rainbow trout, round goby, ruffe, sea lamprey and white perch.

Although Lake Baikal in Russia has a larger volume of water, the combined area of the Great Lakes—some 94,250 square miles (244,106 square kilometres)—represents…, …a fascinating history, as Lakes Superior and Huron were vast synclinal depressions even in Precambrian times. [17] It is also a reflection of relatively small human population and small amount of agriculture in its watershed. Its average depth of is 283 feet while its deepest point is 802 feet. They are still much lower than levels considered dangerous to human health; but this steady, long-term rise is an unusual record of environmental nitrogen buildup.
Because of its large size (relative to watershed area) and the porous "dam" at its outlet, long-term lake-level fluctuations are much lower than in any of the other Great Lakes—generally less than 1 yard (1 metre). Lake Superior Nautical Wood Map … The regulating structure is known as the Compensating Works and is operated according to a regulation plan known as Plan 1977-A.

The lake's water level fluctuates from month to month, with the highest lake levels in October and November. [46][47], Lake Superior has fewer dissolved nutrients relative to its water volume than the other Great Lakes and so is less productive in terms of fish populations and is an oligotrophic lake. Lake Superior's size reduces the severity of the seasons of its humid continental climate (more typically seen in locations like Nova Scotia).

Depth data represents the extent of each water level, as rasters and polygons. (Though Crater Lake is the deepest lake in the United States and deeper than Lake Superior, Crater Lake's elevation is higher and consequently its deepest point is 4,229 feet (1,289 m) above sea level. ArcGIS REST-based map services are available to ingest into an application.
