Lake Nipissing; 8,400 – 5,500 YBP formed as the water bodies in the Superior and Huron basins merged across Sault Ste. Marie around 8,400 YBP and then merged with the Michigan basin around 7,800. [1] Lake Stanley-Hough; 8,700 YBP, the water levels had risen to connect both Lake Stanley and Lake Hough into a single body of water. [1]
Lake Agassiz (/ ˈ æ ɡ ə s i / AG-ə-see) was a large proglacial lake that existed in central North America during the late Pleistocene, fed by meltwater from the retreating Laurentide Ice Sheet at the end of the last glacial period.
The list of drainage basins by area identifies basins (also known as "catchments" or, in North American usage, "watersheds"), sorted by area, which drain to oceans, mediterranean seas, rivers, lakes and other water bodies.
Watersheds of North America are large drainage basins which drain to separate oceans, seas, gulfs, or endorheic basins. There are six generally recognized hydro-logical continental divides which divide the continent into seven principal drainage basins spanning three oceans ( Arctic , Atlantic and Pacific ) and one endorheic basin.
The area of some lakes fluctuates substantially. For those lakes partially in Canada or Mexico the area given for the lake is the total area, not just the part of the lake in the United States. Of the top 100 lakes, 55 are man-made and 45 are natural. Two lakes in the top 100 are primarily salt water, and two are primarily brackish water.
The map of North America with the Western Interior Seaway during the Campanian. The Western Interior Seaway (also called the Cretaceous Seaway, the Niobraran Sea, the North American Inland Sea, or the Western Interior Sea) was a large inland sea that split the continent of North America into two landmasses for 34 million years.
The Great Basin's longest and largest river is the Bear River of 350 mi (560 km), [10] and the largest single watershed is the Humboldt River drainage of roughly 17,000 sq mi (44,000 km 2). Most Great Basin precipitation is snow, and the precipitation that neither evaporates nor is extracted for human use will sink into groundwater aquifers ...
