Lakes by Border of Manitoba, Canada and Minnesota, USA

Canada - May 18th, 2011

Several lakes are visible in this image of the border area by southern Manitoba, Canada (above) and northern USA (below), particularly the states of Minnesota (right) and North Dakota (left).

Visible in Manitoba at the upper edge are the lower parts of Lake Manitoba (left), bright green from sediments and algae, and Lake Winnipeg (right), considerably darker in color.

Near the right edge, are Lake of the Woods (above) and Red Lake (below). The former occupies parts of the Canadian provinces of Ontario and Manitoba and the U.S. state of Minnesota. It separates a small land area of Minnesota from the rest of the United States.

Red Lake is a lake in Beltrami County in northern Minnesota, USA. It is the largest natural freshwater lake in Minnesota. The lake is separated into two sections by a peninsula on the eastern side that almost bisects it in the middle. The lake has a total surface area of 1,148.779 km² (443.546 sq mi). Despite its name, Red Lake, like its neighbor to the north, appears dark blue in color.


Mississippi River and Lake Superior, USA and Canada

USA and Canada - March 30th, 2011

Lake Superior (above), the largest of the five Great Lakes of North America, is bounded to the north by the Canadian province of Ontario and the U.S. state of Minnesota, and to the south by the U.S. states of Wisconsin and Michigan.

Part of Lake Michigan can also be observed at the lower right, and the Mississippi River can be seen crossing the lower part of the image.

The Laurentian Great Lakes are a chain of freshwater lakes located in eastern North America, on the Canada – United States border. Consisting of Lakes Superior, Michigan, Huron, Erie, and Ontario (from left to right), they form the largest group of freshwater lakes on Earth.

The lakes are bound by the Canadian province of Ontario and the U.S. states of Minnesota, Wisconsin, Michigan, Illinois, New York, Indiana, Ohio, and Pennsylvania. Four of the five lakes form part of the Canada-United States border; the fifth, Lake Michigan, is contained entirely within the United States.

The Saint Lawrence River, which marks the same international border for a portion of its course, is the primary outlet of these interconnected lakes, and flows through Quebec and past the Gaspé Peninsula to the northern Atlantic Ocean.

These images were captured in early spring, after warmer temperatures had thawed much of the ice that frequently covers the lakes in winter. However, as can be observed in the close-ups, a patch of ice is still visible at the northernmost tip of Lake Erie, and in the marshy areas along the northern shores of Lake Huron.

Lake Erie has a substantial amont of greenish-yellow sediments clouding its waters from shore to shore. Lake Huron and Lake Michigan also have some sediments, though these are limited to their southern coastlines.

Red River: North Dakota Sees Record Flood Levels

North Dakota and Minnesota, USA - March 29th, 2009

North Dakota and Minnesota, USA - March 29th, 2009

The states of North Dakota (center left), South Dakota (bottom left) and Minnesota (right) in the USA as well as the southern part of Canada’s Manitoba (top left) and Ontario (top right) provinces are all visible here. Lake Superior shows its southwestern tip in the upper right corner.

Recently, North Dakota, Minnesota and Manitoba have all been affected by high water levels in the Red River. The Fargo-Moorhead area in North Dakota saw record flood levels.

The flood is a result of saturated and frozen ground, Spring snowmelt exacerbated by additional rain and snow storms, and virtually flat terrain.

Unlike the vast majority of rivers in the United States, the Red River flows northward, which means melting snow and river ice, as well as runoff from its tributaries, often create ice dams, which cause the river to overflow. The valley is essentially flat, leading to overland flooding, with no high ground on which to take refuge.

The river crest was originally predicted to reach a level of near 43 feet (13 m) at Fargo by March 29, although the river in fact crested at 40.82 feet (12.44 m) at 12:15 a.m. March 28, and started a slow decline. The river continued to rise to the north as the crest moved downstream.

Other climate-related factors also influenced the flooding: ground which was already saturated when it froze at the onset of winter, melting snow which could not be absorbed by the frozen ground, and additional precipitation from a rain storm on March 22 and a later snowstorm.

A low-pressure area caused the rain storm on March 22 and by March 25 a total of 15 to 25 cm (6 to 10 inches) fell in the Winnipeg area, and 20 to 30 cm (8 to 12 inches) in southern Manitoba. In northeastern North Dakota and northwestern Minnesota, around 8 inches of snow accumulated from the same storm.

Ice on Lake Superior

Lake Superior - March 16th, 2009

Ice floats on the surface of Lake Superior, the largest of the five Great Lakes of North America.  As the ice breaks apart, the dark blue waters beneath become visible.

Lake Superior is bounded to the north by Ontario, Canada and Minnesota, United States, and to the south by the U.S. states of Wisconsin and Michigan.

It is the second largest freshwater lake in the world by surface area and is the world’s third-largest freshwater lake by volume.

Lake Superior has a surface area of 31,820 square miles (82,413 km2). It has a maximum length of 350 miles (563 km) and maximum breadth of 160 miles (257 km). Its average depth is 482 feet (147 m) with a maximum depth of 1,332 feet (406 m).

Lake Superior contains 2,900 cubic miles (12,100 km³) of water. In fact, there is enough water in Lake Superior to cover the entire land mass of North and South America with 1 foot (30 cm) of water.

The shoreline of the lake stretches 2,726 miles (4,387 km) (including islands). The lake’s elevation is 600 feet (183 m) above sea level.

Annual storms on Lake Superior regularly record wave heights of over 20 feet (6 m). Waves well over 30 feet (9 m) have been recorded.
