      New microbial source-tracking tools can be used to elucidate important nonpoint sources of water quality degradation and potential human health risks at large scales. Pollution arising from septic system discharges is likely more important than previously realized. Identifying these sources and providing reference levels for water quality provides a basis to assess water quality trends and.

This hydrologic configuration is remarkably similar to the early Holocene Stanley low phase in the Lake Huron basin when waters were more than m lower than present levels due to isostatic. Drainage basin, also called catchment area, or (in North America) watershed, area from which all precipitation flows to a single stream or set of streams.

For example, the total area drained by the Mississippi River constitutes its drainage basin, whereas that part of the Mississippi River drained by the Ohio River is the Ohio’s drainage.

In the region north of Lake Huron, there exist conglomerates and laminated mudstones assigned to the Gowganda Formation. The unsorted conglomerates and varved sands and shales are indicative of glacial conditions. The period of glaciation occurred sometime between and billion years ago.

The lake level curve (gray) originates from Lewis and Anderson (), but was correlated to the Lake Huron sediment cores on the basis of grain size measurements and seismic reflection profiles (Rea et al., a, Moore et al., ).

Lake Huron lake stands are named, and lowstands shaded gray. SP-1 Lake Erie Reference Sites. This project, which predates the existence of the Environmental Radiotracers Project at GLERL, was the outgrowth of sediment deposition studies in Lake Erie initiated in about by the Canada Center for Inland Waters (CCIW).

The Canadian group showed that, at selected sites in the deep eastern basin of the Lake, sediments accumulate at a higher rate than in.

Lake Ontario is the easternmost of the Great Lakes and the smallest in surface area (7, sq mi, 18, km 2), although it exceeds Lake Erie in volume ( cu mi, 1, km 3).It is the 13th largest lake in the its islands are included, the lake's shoreline is miles (1, km) long.

Lake Michigan also has the world's largest freshwater dunes. The basin contains the most farmland of all the Great Lakes Basin, with 44% of its drainage basin devoted to agriculture, while 41% is forested and 9% is residential. Lake Huron Lake Huron has the longest shoreline of the Great Lakes and includes thousands of islands.

As recently asLake Maracaibo suppor fishermen. Settlements. Several settlements built out on stilts over the lake – palafitos – still exist in the south and south-west, notably at Lagunetas.

Subsiding ground. Due to the massive volume of oil removed in the Maracaibo Basin, some oil-producing areas adjacent to Lake Maracaibo have sunk, changing the geography of the region. The Niagara Escarpment is a long escarpment, or cuesta, in the United States and Canada that runs predominantly east/west from New York, through Ontario, Michigan, Wisconsin, and escarpment is most famous as the cliff over which the Niagara River plunges at Niagara Falls, for which it is named.

The Escarpment is a UNESCO World Biosphere Reserve. Lake Michigan is one of the five Great Lakes of North America and the only one located entirely within the United States.

It is the second-largest of the Great Lakes by volume (1, cu mi (4, km 3)) and the third-largest by surface area (22, sq mi (58, km 2)), after Lake Superior and Lake Huron (and is slightly smaller than the U.S.

[1] When measured at the Low Water Datum, the lake contains a volume of cubic miles (3, km 3) and a shoreline length (including islands) of. Areas where scud are known to be rare or absent include the southern, southeastern and northern portions of Lake Michigan at depths less than 70 meters, almost all of Lake Ontario at depths less than 70 meters, the entire southern end of Lake Huron, and the Eastern Basin of Lake Erie.

In other areas of these Lakes, scud are still present, but. Area of circles are proportional to the number of angler days in Lake Superior - Lake Michigan - 5 Lake Huron - Lake Erie - 7 Lake Ontario - 2 2.

A rare cloudless satellite view of the entire Great Lakes region, April. Geology of the Cutler Area; District of Algoma - Geology Ontario. Lake Superior is the head of the Great Lakes, so it would be easy to think of it as a headwaters that irrigate lakes Huron, Michigan, Erie and Ontario.

(Lake Superior has the equivalent water, after all, of the other four lakes, plus three additional Lake Eries.) Actually, the other Great Lakes are older than our lake. Lakes Michigan and Huron are hydrologically a single lake, sometimes called Lake Michigan-Huron, with a total area of 45, square miles (, km 2) [5] they have the same surface elevation of feet ( m), [10] and are connected not by a river but by the foot (90 m) deep Straits of Mackinac.Water-level data for the Albuquerque Basin and adjacent areas, central New Mexico, period of record through Septem Adjusted geomagnetic data are magnetometer measurements with provisional correction factors applied such that vector quantities are oriented in a local Cartesian frame in which the X axis points north, the Y axis points.The trophic status of the North American Great Lakes, including Great Bear Lake and Great Slave Lake, was summarized by Robertson and Scavia ().

They concluded that Lakes Ontario and Erie are eutrophic and that Green Bay (Lake Michigan), Saginaw Bay (Lake Huron), and the Lake Erie western basin are highly eutrophic.
