The Americas

Gulf of Mexico
an ocean basin largely surrounded by the North American continent and the island of Cuba.[1] It is bounded on the northeast, north and northwest by the Gulf Coast of the United States, on the southwest and south by Mexico, and on the southeast by Cuba.[image]
Bering Sea

The Bering Sea is a marginal sea of the Pacific Ocean.[1][2] It comprises a deep water basin, which then rises through a narrow slope into the shallower water above the continental shelves.

The Bering Sea is separated from the Gulf of Alaska by the Alaska Peninsula. It covers over two million square kilometers, bordered on the east and northeast by Alaska, on the west by Russia’s;Siberia;and;Kamchatka Peninsula, on the south by the Alaska Peninsula and the;Aleutian Islands;and on the far north by the;Bering Strait, which connects the Bering Sea to theArctic Ocean’s Chukchi Sea. 

Hudson Bay
Hudson Bay (Inuktitut: Kangiqsualuk ilua,[1] French: baie d’Hudson), sometimes (usually historically) called;Hudson’s Bay, is a large body of saltwater in northeastern Canada. It drains a very large area, about 3,861,400 square kilometres (1,490,900 sq mi),[2] that includes parts of Ontario, Quebec, Saskatchewan, Alberta, most of Manitoba, southeastern Nunavut, as well as parts of North Dakota, South Dakota, Minnesota, and Montana. The southern arm of Hudson Bay is called James Bay.
Lake Champlain
Lake Champlain (French: lac Champlain) is a natural, freshwater lake in North America, located mainly within the borders of theUnited States (states of Vermont and New York) but partially situated across the Canada-United States border in the Canadianprovince of Quebec.
The Great Lakes

The Great Lakes, sometimes disambiguated as the Laurentian Great Lakes, are a collection of freshwaterlakes located in northeastern North America, on the Canada–United States border, which connect to theAtlantic Ocean through the Saint Lawrence Seaway and the Great Lakes Waterway. Consisting of LakesSuperior, Michigan, Huron, Erie, and Ontario, they form the largest group of freshwater lakes on Earth, containing 21% of the world’s surface fresh water.[1][2][3];The total surface is 94,250 square miles (244,106;km2), and the total volume (measured at the low water datum) is 5,439;cubic miles;(22,671;km3).[4]The lakes are sometimes referred to as the North Coast or “Third Coast” by some citizens of the United States.

[image]The lakes have been a major source of trade through this area, and they are home to a large number of aquatic species. Many invasive species have been introduced due to trade in the area, and some threaten the biodiversity of the area.

Mississippi River
The;Mississippi River;is the chief river of the largest;river system;in North America.[3][4];Flowing entirely in the United States (though its;drainage basin;reaches into Canada), it rises in northern;Minnesota;and;meanders;slowly southwards for 2,530 miles (4,070;km)[5];to the;Mississippi River Delta;at the;Gulf of Mexico. With its many;tributaries, the Mississippi’swatershed drains all or parts of 31 US states and 2 Canadian provinces between the Rocky and Appalachian Mountains. The Mississippi ranks as the fourth longest and tenth largest river in the world. The river either borders or cuts through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana.
Missouri River
The Missouri River is the longest river in North America and a major waterway of the central United States. Rising in theRocky Mountains of western Montana, the Missouri flows east and south for 2,341 miles (3,767 km)[7] before entering theMississippi River north of St. Louis, Missouri. The river takes drainage from a sparsely populated, semi-arid watershed of more than half a million square miles (1,300,000 km2), which includes parts of ten U.S. states and two Canadian provinces.
Ohio River
The Ohio River (Seneca: ohi:yó[2]) is the largest tributary, by volume, of the Mississippi River. At the confluence, the Ohio is even bigger than the Mississippi (Ohio at Cairo: 281,500 cu ft/s (7,960 m3/s);[3] Mississippi at Thebes: 208,200 cu ft/s (5,897 m3/s)[4]) and, thus, is hydrologically the main stream of the whole river system, including the Allegheny River further upstream. It is approximately 981 miles (1,579 km) long and is located in the Eastern United States.
Tennessee River
The Tennessee River is the largest tributary of the Ohio River. It is approximately 652 miles (1049 km) long and is located in thesoutheastern United States in the Tennessee Valley. The river was once popularly known as the Cherokee River, among other names.[2] Its name is derived from the Cherokee village name Tanasi.[5]
Red River
The Red River (French: Rivière rouge, German: Roter Fluss, American English: Red River of the North) is a North Americanriver. Originating at the confluence of the Bois de Sioux and Otter Tail rivers between the U.S. states of Minnesota and North Dakota, it flows northward through the Red River Valley, forming the border of Minnesota and North Dakota and continuing intoManitoba, Canada. It empties into Lake Winnipeg, whose waters join the Nelson River and ultimately flow into the Hudson Bay, which is considered part of the Arctic Ocean.
Arkansas River
The Arkansas River (Pawnee: Kícka [5]) is a major tributary of the Mississippi River. The Arkansas generally flows to the east and southeast as it traverses the U.S. states of Colorado, Kansas, Oklahoma, and Arkansas. The river’s initial basin starts in theWestern United States;in;Colorado, specifically the Arkansas River Valley where the headwaters derive from the;snowpack;in theCollegiate Peaks. Then it flows east into the;Midwest;via Kansas, and finally into the;South;through Oklahoma and Arkansas.
Rio Grande River
The;Rio Grande;(known in Mexico as the;R;o Bravo del Norte, or simply;R;o Bravo) is a;river;that flows from southwesternColorado;in the;United States;to the;Gulf of Mexico. Along the way it forms part of the;Mexico ; United States border. According to the;International Boundary and Water Commission, its total length was 1,896 miles (3,051;km) in the late 1980s, though course shifts occasionally result in length changes. Depending on how it is measured, the Rio Grande is the fourth or fifth longest river system in North America.[2]
Colorado River
The;Colorado River;is the principal river of the;southwestern;United States;and northwest;Mexico. The 1,450-mile (2,330;km) river drains an expansive, arid;watershed;that encompasses parts of seven U.S. and two Mexican states. Rising in the central;Rocky Mountains;in the U.S., the river flows generally southwest across the;Colorado Plateau;before reaching;Lake Mead;on theArizona;Nevada;line, where it turns south towards the international border. After entering Mexico, the Colorado forms a large;delta, emptying into the;Gulf of California;between;Baja California;and;Sonora.
St. Lawrence River
The;Saint Lawrence;(French:;fleuve Saint-Laurent;;Tuscarora:;Kahnaw;?kye;[3];Mohawk:;Kaniatarowanenneh, meaning “big waterway”) is a large;river;flowing approximately from southwest to northeast in the middle latitudes of;North America, connecting the;Great Lakes;with the;Atlantic Ocean. It is the primary drainage conveyor of the;Great Lakes Basin. The river traverses theCanadian provinces;of;Quebec;and;Ontario;and forms part of the;international boundary;between Ontario and;New York;in theUnited States.
Mackenzie River
The;Mackenzie River;(Dene:;Deh-Cho,;big river) is the largest;river;system in;Canada. It flows through a vast, isolated region of forest and;tundra;entirely within the country’s Northwest Territories, although its many tributaries reach into four other Canadian provinces and territories. The river’s;mainstem;runs 1,738 kilometres (1,080;mi) in a northerly direction to the;Arctic Ocean, draining a vast area nearly the size of;Indonesia. It is the largest river flowing into the Arctic from;North America, and with its tributaries is one of the;longest rivers in the world.
hudson river
The;Hudson River;is a 315-mile (507;km);watercourse;that flows from north to south through eastern;New York State;in the;United States. The river begins at the confluence of Calamity Brook and Indian Pass Brook near;Henderson Lake;in;Newcomb, New York. The river flows southward past the state capital at;Albany;and then eventually forms the boundary between;New York City;and the;U.S. state;of;New Jersey;at its mouth before emptying into;Upper New York Bay. Its lower half is a;tidal estuary,[3];which occupies the;Hudson Fjord. This formed during the most recent North American;glaciation;over the latter part of the Wisconsin Stage of the Last Glacial Maximum, 26,000 to 13,300 years ago.[4];Tidal waters influence the Hudson’s flow as far north as Troy, New York.
Chesapeake Bay
The Chesapeake Bay ([image] /?t??s?pi?k/ chess-?-peek) is the largest estuary in the United States.[2] It lies off the Atlantic Ocean, surrounded by Maryland and Virginia. The Chesapeake Bay’s;drainage basin;covers 64,299 square miles (166,534;km2) in theDistrict of Columbia;and parts of six states:;New York,;Pennsylvania,;Delaware,;Maryland,;Virginia, and;West Virginia.[3];More than 150 rivers and streams drain into the bay.[2]
susquehana river
The;Susquehanna River;([image];/?s?skw??h;n?/) (Lenape: Sisk;wahane;[3]) is a;river;located in the northeastern;United States. At 464 miles (747;km) long,[4];it is the longest river on the;American east coast;that drains into the;Atlantic Ocean, and with its;watershedit is the 16th largest river in the United States,[5][6];and the longest river in the continental United States without commercial boat traffic.[7];It flows through three states:;New York,;Pennsylvania, and;Maryland. It forms from two main branches, with the “North Branch”, which rises in upstate;New York, regarded by federal mapmakers as the main branch.[1];The shorter;West Branch, which rises in western;Pennsylvania, joins the main stem near;Northumberland;in central Pennsylvania.
delaware bay
Delaware Bay;is a major;estuary;outlet of the;Delaware River;on the Northeast seaboard of the;United States;whose fresh water mixes for many miles with the waters of the;Atlantic Ocean. It is 782 square miles (2,030;km2) in area.[1];The bay is bordered by the State of;New Jersey;and the State of;Delaware. It was the first site classified in the;Western Hemisphere Shorebird Reserve Network.
columbia river

The;Columbia River;is the largest;river;in the;Pacific Northwest;region of;North America.[9];The river;rises;in the;Rocky Mountains;of;British Columbia,;Canada. It flows northwest and then south into the;U.S. state;of;Washington, then turns west to form most of the border between Washington and the state of;Oregon;before emptying into the;Pacific Ocean. The river is 1,243 miles (2,000;km) long, and its largest;tributary;is the;Snake River. Its;drainage basin;is roughly the size ofFrance;and extends into seven U.S. states and a Canadian province.

By volume, the Columbia is the fourth-largest river in the U.S., and it has the greatest flow of any North American river draining into the Pacific. The river’s heavy flow and its relatively steep gradient gives it tremendous potential for the generation of electricity. The 14 hydroelectric dams on the Columbia’s;main stem;and many more on its tributaries produce more;hydroelectric power;than those of any other North American river.

american river
The;American River;(R;o de los Americanos;during the Mexican-ruled period before 1846) is a;California watercourse;river system which runs from the crest of the;Sierra Nevada;mountain range;to its confluence with the;Sacramento River;inSacramento, California. The Sacramento River continues to eventually empty into the San Francisco Bay and the Pacific Ocean at;San Francisco, California. The American River flows entirely within California.
