freshwater stingray great lakes

[citation needed], Blue-green algae, or Cyanobacteria blooms,[93] have been problematic on Lake Erie since 2011. [63] Since the glaciers covered some areas longer than others, this glacial rebound occurred at different rates. The brigantine Le Griffon, which was commissioned by René-Robert Cavelier, Sieur de La Salle, was built at Cayuga Creek, near the southern end of the Niagara River, and became the first known sailing ship to travel the upper Great Lakes on August 7, 1679.[108]. Local sewage treatment authorities then must release untreated effluent, a mix of rainwater and sewage, into local water bodies. The Great Lakes are also connected by the Chicago Sanitary and Ship Canal to the Gulf of Mexico by way of the Illinois River (from the Chicago River) and the Mississippi River. The lake is the outlet of the Great Lakes chains and connects to the Atlantic Ocean through Saint Lawrence River. The number of such overflow events in Ontario, for example, is flat according to the International Joint Commission. The Erie Canal connects to the Great Lakes at the east end of Lake Erie (at Buffalo, New York) and at the south side of Lake Ontario (at Oswego, New York). The first of 43 "Great Lakes Areas of Concern" to be formally "de-listed" due to successful cleanup was Ontario's Collingwood Harbour in 1994; Ontario's Severn Sound followed in 2003.

While enormous public investments such as the Deep Tunnel projects in Chicago and Milwaukee have greatly reduced the frequency and volume of these events, they have not been eliminated. The goby is considered undesirable for several reasons: it preys upon bottom-feeding fish, overruns optimal habitat, spawns multiple times a season, and can survive poor water quality conditions. In 1998, the Canadian company Nova Group won approval from the Province of Ontario to withdraw 158,000,000 U.S. gallons (600,000 m3) of Lake Superior water annually to ship by tanker to Asian countries.

If a shark was to travel in from the Atlantic Ocean through the St. Lawrence River, it would have to pass the dams that break up the St. Lawrence Seaway. By the mid-1980s, most jurisdictions bordering the Great Lakes had controlled phosphate detergents,[92] resulting in sharp reductions in the frequency and extent of the blooms. Although the Saint Lawrence Seaway and Great Lakes Waterway make the Great Lakes accessible to ocean-going vessels,[37] shifts in shipping to wider ocean-going container ships—which do not fit through the locks on these routes—have limited container shipping on the lakes. The largest and last major freighter wrecked on the lakes was the SS Edmund Fitzgerald, which sank on November 10, 1975, just over 17 miles (30 km) offshore from Whitefish Point on Lake Superior.

As a chain of lakes and rivers they connect the east-central interior of North America to the Atlantic Ocean. [71], On both sides of the Canada–United States border, the proliferation of dams and impoundments have multiplied, necessitating more regulatory efforts. The lakes also moderate seasonal temperatures to some degree, but not with as large an influence as do large oceans; they absorb heat and cool the air in summer, then slowly radiate that heat in autumn. When a second fault line, the Saint Lawrence rift, formed approximately 570 million years ago,[14] the basis for Lakes Ontario and Erie were created, along with what would become the Saint Lawrence River. [74] By 1938, Wisconsin's commercial fishing operations were motorized and mechanized, generating jobs for more than 2,000 workers, and hauling 14 million pounds per year.
