Beaver River

*can not find a picture yet! I'll keep looking!*

Rising up from springs and creeks in the Feversham area, the Beaver River meanders 40 kilometres to Georgian Bay. It also meets up with the Boyne River just west of Eugenia. For much of its course, the Beaver runs through a heavily wooded swamp dominated by silver maple, black ash and trembling aspen. Ostrich ferns line the banks, and wildlife is abundant. Wood ducks, hooded mergansers, green herons, great horned owls and snapping turtles are regularly seen on the Beaver. The river is a popular canoe and kayak route, especially in spring, when it attracts whitewater enthusiasts. Anglers also come for the river's brown and rainbow trout.

The Petun Indians gave the Beaver River its name. One historian even speculated that the use of the Beaver as Canada's national emblem originated with the Petun from Grey County. On their fur trading missions, they carried shields decorated with a beaver ensign.

The Beaver is a good example of a misfit river - one that is too small to have created such a large valley. Hundreds of thousands of years ago, before the glaciers advanced over southern Ontario, the sprawling valley carried a much larger river. It eroded down through the soft limestone bedrock, creating one of the Escarpment's largest valleys. Then the glaciers smoothed and widened the valley to more than ten kilometres across in places.

The Taku River

  photo   Taku River

American Rivers, a "watershed watchdog" group, describes the Taku as "forming the heart of a 7,000-square-mile watershed in British Columbia and Alaska". To date the entire watershed is untouched by commercial logging, significant mining, or settlement activity. The Taku River is the largest unprotected wilderness river system on the western shore of North America and the largest watershed south of the Alsek-Tatshenshini river system and north of the Stikine River.

The source of the Taku is approximately 105 miles northeast of Juneau, Alaska. The lower 25 miles of the river flow through Alaska's Tongass National Forest and have been found eligible for inclusion in the National Wild and Scenic Rivers System because of their outstanding fish and wildlife, scenic and geological values. The Taku River in British Columbia has been nominated for inclusion in the Canadian Heritage Rivers system based upon it's natural and cultural values.The upper drainage is the traditional home of the River Tlingit First Nation, who establish traditional fish camps each summer along the river to harvest salmon for winter use.

Moose, mountain goats, black bears, and grizzlies are present throughout the Taku watershed, and the upper reaches are important wintering grounds for woodland caribou. Sensitive fish and wildlife near the mouth of the river include eulachon ad harbour seals. Bird life is rich and varied with teaming population of bald eagles and a lone Steller's sea eagle - a rare Asian variant virtually never found further east than the Aleutian Islands".

*Taku River (TAI-koo), 180 mi/290 km long, N B.C., Canada, and SE Alaska; rises W of Dease L.; flows generally W to Coast Mts. SE of Atlin L., then SW, crossing into Alaska 5 mi/8 km SW of Tulsequah, to Taku Inlet 25 mi/40 km NE of Juneau. *

Klamath River

The Klamath River, approximately 250 mi (400 km) long, is a major river of the Pacific coast in southern Oregon and northern California in the United States. It drains an arid farming valley in its upper reaches, passing swiftly through the mountains in its lower reaches before emptying into the ocean. It is one of only three rivers that pass through the Cascade Range (the others being the Fraser River in British Columbia and the Columbia River between Oregon and Washington), and the second longest river in California.

The Lower Klamath River below Happy Camp.

It issues from the southern end of Upper Klamath Lake in southern Oregon just above the town of Klamath Falls. It flows roughly southwestward into northern California, passing through the Klamath Mountains and along the southern side of the Siskiyou Mountains. It enters the Pacific at Klamath in Southwestern Del Norte County, approximately 20 mi (32 km) SSE of Crescent City.


The name of the river comes from a Native American word klamet meaning "swiftness". It provided a significant passage for the nearby Native American tribes to pass through the Cascades. Archeological evidence in the valley suggests it has been inhabited for at least 7,000 years. The river and its fish are considered sacred by resident Native American tribes, which include the Yurok, Hupa, and Karuk tribes, as well a confederation of the Klamath, Modoc, and Yahooskin people known as The Klamath Tribes. The Phoebe A. Hearst Museum in Berkeley, California contains a collection of carvings from some of the tribes in this region.

An 11-mile section of the river in Oregon south of Klamath Falls to the California-Oregon border, including the Hell's Corner Gorge, has been designated as the Klamath Wild and Scenic River.

The river is considered a prime habitat for king salmon AKA Chinook salmon, Coho salmon AKA silver salmon, steelhead trout, and rainbow trout. Once the third-largest producer of salmon on the West Coast, the river has produced only a fraction of its historic runs since the construction of six dams built between 1908 and 1962. The possible removal of the dams has been a controversial issue in the region in recent years. Despite intense lobbying by local Native American tribes, conservationists, and fishermen, the 2004 renewal application by PacifiCorp for another 50-year federal operating licence for the dams did not include any provisions for allowing salmon to return to over 300 miles of former habitat above the dams.

The Indus River


The Indus, (known in Tibetan as the Sengge Chu ('Lion River') and in Sanskrit and Hindias the Sindhu) is the longest and one of the most important rivers in South Asia. Originating in the Tibetan plateau in the vicinity of Lake Mansarovar, the river runs a course through Kashmir in both India and Pakistan, and in a southernly direction along the entire length of Pakistan to merge into the Arabian Sea. Figures for the total length of the river vary between 2,900 and 3,200 kilometres. The river has a total drainage area exceeding 450,000 miles. The river's estimated annual flow stands at around 207 billion cubic metres. Beginning at the heights of the world with glaciers, the river feeds the ecosystem of temperate forests, plains and arid countryside. Together with the rivers Chenab, Ravi, Sutlej, Jhelum, Beas and the extinct Sarasvati River, the Indus forms the Sapta Sindhu (Seven rivers) delta in the Sindh province of Pakistan. It has 20 tributaries.

The Indus was the primary support and base of the Indus Valley Civilization - one of the earliest in world history - which arose along its course. The Rigveda (c. 1500 BCE) first mentions the river. The Indus is the English name derived from Sinthos in Greek, and Sindus in Latin. The name India is derived from the root of the river's name. The region through which it passes prior to entering the sea is named Sindh - home to ancient kingdoms, now a province in Pakistan. The river is considered sacred in Hinduism - the term Hindu itself is derived from Sindhu - and is worshipped by Hindus. The Indus provides the key water resources for the economy of Pakistan - especially the breadbasket of Punjab province, which accounts for most of the nation's agricultural production, and Sindh. It also supports many heavy industries and provides the main supply of potable water in Pakistan.

Accounts of the Indus valley from the times of Alexander's campaign indicate a healthy forest cover in the region, which has now considerably receeded. The Mughal Emperor Babar writes of encountering rhinoceroses along its bank in his memoirs (the BaberNameh). Extensive deforestation and human interference in the ecology of the Shivalik Hills has led to a marked deterioration in vegetation and growing conditions. The Indus valley regions are arid with poor vegetation. Agriculture is sustained largely due to irrigation works.

 The Indus River Dolphin is a sub-species of Dolphins found only in the Indus River. It formerly also occurred in the tributaries of the Indus river. Palla fish (Hilsa ilisha) of the river is a delicacy for people living along the river. The population of fishes in the river is moderate, with Sukkur, Thatta and Kotri being the major fishing centres - all in the lower Sindh course. But damming and irrigation has made fish farming an important economic activity. Located southeast of Karachi, the large delta has been recognised by conservationists as one of the world's most important ecological regions. Here the river distributes into many marshes, streams and creeks and meets the sea at shallow levels. Here marine fishes are found in abundance, including pomfret and prawns.

El Fuerte River

The Fuerte River is a river in the northwestern Mexican state of Sinaloa. It is formed at the junction of the Verde and Urique rivers. The course Fuerte River lies close to the city of Los Mochis. The river is surrounded by large mango plantations which produce the fruits mainly for export to the United States.

Humber River, Ontario

The 100 km Humber River has its headwaters in the ancient rock of the Niagara Escarpment and the glacial hills of the Oak Ridges Moraine. It flows placidly through a rich mosaic of Carolinean forests and meadows, past farms and abandoned mills, before meandering through the largest urban area in Canada, metropolitan Toronto. Here, the Humber is in the backyard of more than three million people, a unique river that flows through the most densely populated area of Canada but still retains many of its natural and cultural values. The river is being protected and restored as a vibrant ecosystem with the help of many individuals, groups and agencies who share a common vision of a healthy Humber. A unique system of greenways along its course maintains the spirit of the historic Toronto Carrying Place Trail, and provides an urban oasis. Brook trout still thrive in its clear headwaters. Its wetlands still ring with the choruses of birds and frogs. The Humber shows us that, with a caring attitude, we can have development, and a diverse, vibrant river.

The Humber River has a long history of human settlement along its banks. As revealed by extensive archaeological evidence, native settlement in the Humber watershed came in three waves. The earliest settlers were the Palaeo-Indians who lived in the area from 10,000 to 7,000 BC and survived mainly by hunting large game. The second wave of native settlers, the people of the Archaic period, resided in the Humber region between 7,000 and 1,000 BC and began to adopt seasonal migration patterns to take advantage of available plants, fish and game. The third wave of native settlement was the Woodland period. The Woodland period saw the introduction of the bow and arrow and the growing of crops which allowed for larger, more permanent villages. The Woodland period was also characterized by movement of native groups into and out of the watershed mainly via the historic overland route (now known as the Toronto Carrying-Place Trail) which linked Lake Ontario to the upper Great Lakes and the north.

Étienne Brűlé was the first European to encounter the Humber River and to travel the ancient Toronto Carrying-Place Trail. Brűlé passed through the watershed in 1615, on a mission from Samuel de Champlain to build alliances with native peoples. The Toronto Carrying-Place Trail became a convenient shortcut to the upper Great Lakes for traders, explorers, and missionaries. Due to its historical importance, the Toronto Carrying-Place Trail has been designated as nationally significant by the Federal Historic Sites and Monuments Board.

The French occupied the Humber region until 1793, with prominent French trader and native language interpreter Jean-Baptiste Rousseau being the first European to take up permanent residence on the Humber. Rousseau piloted Lieutenant Governor Simcoe’s ship into Toronto Bay to officially begin the British era of settlement in 1793. Settlement of the Toronto region remained scattered until after the war of 1812 when immigration from Scotland, Ireland, and elsewhere in Europe increased. By 1830, villages were starting to be established near mills and major roads and more widespread development began.

Some other notable residents, explorers, missionaries and military individuals whose careers and works are strongly associated with the Humber River include, Fathers Jean de Brebeuf and Joseph Chaumonot (1641), Father Louis Hennepin (1678), Rene-Robert Cavelier de La Salle (1680), the Eaton Family, and Janet and Pierre Berton.

Today, many communities throughout the Humber watershed still reflect evidence of the early history of the Humber. For example, the Seed-Barker archaeological site near Woodbridge reveals the history of Aboriginal settlement in the mid sixteenth century and is investigated by high school students from around the world each year as part of the outdoor educational program at Boyd Field Centre; the King Railway Station, built in 1853 by the Northern Railway, is the oldest surviving railway station in Canada; Eaton Hall, built by the Eaton family who founded the Eatons department stores, now forms the heart of Seneca College in Toronto; and the former home of Robert and Signe McMichael now houses one of the largest permanent displays of works by Tom Thomson, the Group of Seven and their contemporaries at the McMichael Canadian Art Collection.

The Red Cedar in autumn.

The Red Cedar River (45 mi/72 km long) is a river in Michigan which is a tributary of the Grand River. Its source is east of Williamston; it runs about 45 miles through Okemos, East Lansing, including the campus of Michigan State University, and finally Lansing where it empties into the Grand River. It is not navigable by boats any larger than recreational size, and is not an important shipping route. Its watershed area is estimated at 472 square miles, and it has 12 tributaries of its own. Because of frequent bacterial contamination, the river serves as a tool to teach local students the importance of clean water. The river is named for the trees commonly known as "red cedar" that were prevalent and still are somewhat common near the river's source and beginning length. The tree however, is properly a type of juniper, Juniperus virginiana.

Madeira River

Madeira (mudā'ru), c.2,100 mi (3,380 km) long, formed by the junction of the Beni and Mamoré rivers on the Bolivia-Brazil border. It flows north along the border for c.60 mi (100 km), then northeast in a winding course through the Rondônia and Amazonas sections of NW Brazil into the Amazon River. At its mouth is Ilha Tupinambaranas, an extensive marshy region formed by the Madeira's distributaries. The river receives numerous tributaries from the southeast and is navigable by ocean vessels to the falls and rapids near Pôrto Velho, Brazil. There the Madeira-Mamoré RR begins a 227 mi (365 km) run around the unnavigable section to Guajará-Mirim on the Mamoré River.

Save the Amazon’s Madeira River!

The Amazon is under threat. The Brazilian government is planning to build two massive dams on one of the Amazon’s most important tributaries, the Madeira River. The projects would push many species to the brink of extinction, and would affect the land and livelihoods of thousands of river bank dwellers and indigenous people. But it is not too late. With your help we can show the Brazilian government that the rivers of Amazonia are worth protecting. Write to the Brazilian Environment Minister and the Mines and Energy Minister telling them the Madeira is too important a treasure to destroy.

Rio Grande

Rio Grande , river, c.1,885 mi (3,000 km) long, rising in SW Colo. in the San Juan Mts. and flowing south through the middle of N.Mex., past Albuquerque, then coursing generally southeast as the border between Texas and Mexico, making a big bend (see Big Bend National Park), and eventually emptying into the Gulf of Mexico at Brownsville, Tex., and Matamoros, Mex. Other paired towns along the river are Laredo, Tex., and Nuevo Laredo, Mex. and El Paso, Tex., and Juárez, Mex. The river, known in Mexico as Río Bravo del Norte, is unnavigable except near its mouth, but is now often reduced to a trickle there by drought and the drawing off of water upstream.

The Rio Grande is an important source of internationally regulated irrigation, a use it has long been put to. Pueblos were thriving on its banks N of Las Cruces, N.Mex., and the Native Americans were practicing irrigation of the arid country, when Spanish explorer Francisco Vásquez de Coronado arrived (1540). Today, dams on the Rio Grande are used for irrigation, flood control, and regulation of the river flow. Elephant Butte Dam (completed 1916) and Caballo Dam (completed 1938) in New Mexico create reservoirs that serve large areas. Further downstream N of Del Rio, Tex., is the Amistad Dam (completed 1969); it is 6 mi (9.7 km) long and impounds a huge reservoir; Amistad National Recreation Area is there. Below Laredo are Falcon Dam (completed 1954) and its large reservoir. Near the mouth of the Rio Grande is the irrigation-dependent citrus-fruit and truck-farm region commonly called the Rio Grande Valley and developed principally in the 1920s. An agreement between the United States and Mexico in 1944 provided for future distribution of the river's water, but in drought years the amount reaching the United States is often less than what is called for under the treaty.

Shifts in the river's channel have led to border disputes between the United States and Mexico. Parts of its bed have been stabilized by canalization, and an international border commission mediates disputes. The 114-year controversy over the location of the border at El Paso was finally settled in 1968 when the water of the Rio Grande was diverted into a concrete channel. A 191-mi (307-km) section of the river on the American shore below Big Bend National Park is protected as the Rio Grande Wild and Scenic River. (see National Parks and Monuments, table).

Rhine River

The Rhine River begins in the Rheinwaldhorn Glacier of Switzerland and flows north and east approximately 820 miles (1,320 km). It is a principal river of Europe.

Because of the multi countries and languages, the river has three names. They are: Rhein, Germany; Rhine, France; and Rijn, Netherlands (Dutch). There are many other important tributaries that flow into the Rhine, in fact the Rhine splits into two tributaries near Emmerich, Germany and Zevenaar, Netherlands. Those are the Lek on the north and the Waal on the south. Some of the main tributaries are: the Mosselle (Mosel), that runs south west bordering Luxembourg and on into France; the Neckar that flows south east at Manneheim on through Heidelburg, Germany; the Main, flowing east and south from Mainz through Frankfurt, Germany. East of Frankfurt is where The Rhine-Main-Danube Canal links the Rhine with the Danube providing a transcontinental route from the North Sea to the Black Sea.
The castles are an unmistakable feature of the Rhine landscape. Their founders were feudal overloards, who built them to protect their lands from marauders. They were far from thinking of any romantic notions as we do today. Besides the warlike function for which they were built, think about the back-breaking labor of the feudal serfs, whom must have been forcibly employed in quarring the huge stone blocks and dragging them up the mountain slopes.

The mid-Rhine is also known for its German legends. One of the best known is the story of the Lorelei. As the story goes, a nymph lived in the Lorelei rock high above the Rhine. She is said to have lured fishermen to their destruction with her singing until she was overcome with love and plunged to her own death. A bronze statue of the nymph overlooks the river.

Along the Rhine, particularly in the narrow gorge connecting Bingen and Koblenz , which has a length of only thirty-five miles, there are more castles than in any other river valley in the world. Many are ruins, but some have been restored as hotels and are open for tours. They stand like sentinels on the cliffs above river side villages and others stand alone surrounded by vineyards.

In the French regions of Alsace and Lorraine there are quite a few castles too. One of those is the one in Kayersberg built in the early 1200's. Another is the Mont Sainte Odile, founded by St Odile in the 7th century, is said to have over a million visitors a year. The most visited and well known is the Haut-Koenigsbourg. It rises out of the forest of Selestat and was in ruins in the 1890's. It was fully restored by Bodo Ebhardt after the ruins were given to the Kaiser when the Alsace was in German possession.

The Amazon River is the second longest river in the world, and the largest in terms of the size of its watershed, the number of tributaries, and the volume of water discharged into the sea. No bridge crosses the river along its entire length.  

The Amazon and its tributaries flow through the countries of Peru, Bolivia, Venezuela, Colombia, Ecuador, and Brazil before emptying into the Atlantic Ocean 6, 437 kilometers (4,000 miles) from the Amazon's headwaters high in the Andes mountains of Peru. This huge watershed includes the largest tropical rainforest in the world as well as areas of dry grassland, or savannah.  

The rainforest's climate has heavy rainfalls and continuous high temperatures. These forests are so huge that scientists believe they actually help control the world's climate in important ways. Destruction of the forests as settlers clear the land for farming and companies harvest trees for lumber is believed to be contributing to the problem of global warming.  

The Amazon is home to a variety of  Indian cultures who have a great deal of knowledge about the rich and complex rainforest environment. As settlement brings changes to the forest, these cultural groups are also changing, and the lessons they have gained through thousands of years of living within the rainforest are in danger of being lost.  Scientists are trying to learn from the Amazon's native peoples about the amazing variety of rainforest plants and animals before they become extinct. Rainforest plants and animals may hold cures to diseases and provide information and materials valuable to people around the world.

Absolutely ... Thank you, ScB!

And one that I used to visit quite a bit when I was a kid:

The Danube River

anubemap.JPG" rel="nofollow" >A map showing the Danubeanubemap.JPG" />

The Danube River is the second longest river in Europe where it is one of the major methods of transportation.  One reason for this is the fact that it is the only major European river to flow west to east.  The source of the river is located in the Black Forest area of Germany.  From there, it flows about 1,770 miles to the east.  The mouth of the river forms a delta on the Romanian coastline of the Black Sea.

The Danube River has been used as an important means of transportation of soldiers for nearly 2,000 years.  In the 200s, the river was the northern border of the Roman Empire, and Roman soldiers no doubt used the river.  Years later, the Goths, Slavs, Huns, and other Germanic tribes used the Danube to cross into the Roman Empire.  Later, the Danube was used to gain access to Constantinople.  The Crusaders used the Danube to travel faster on their quest to regain the Holy Land.  Towards the end of the Middle Ages, the Ottoman Turks used the Danube for easier advancement into western and central Europe.

Both the commercial and military value of the Danube are still recognized today.  Many treaties have been signed to try to keep one country from having too much control of it.  In the early part of the 19th century, the Danube served as a link between the industrial area of Germany and farmland of  the Balkans.  At this time, the Ottoman Empire was weakening, but the Russian Empire was near the height of its power.  Austria and other powerful European nations recognized this threat to the area and were able to prevent Russia from gaining the Danube delta.

One may ask why the Danube is so important.  The answer to this question is two-fold.  The first part of the answer is its use for commercial and military transportation.  The second part of the answer is the location of the Danube.

The Danube flows through the countries of Germany, Austria, Slovakia, Hungary, Serbia, Croatia, Bosnia and Herzegovina, Slovenia, Bulgaria, Romania, and the Ukraine.  There are many important cities that the Danube flows through.  They include Vienna, Budapest, Bratislava, and Belgrade.  With the aid of canals, the Danube is connected to the Main, Oder, and Rhine Rivers.  This waterway connects the North and Black Seas.  For commercial transportation, the Danube is extremely valuable.

In addition to the Danube’s importance as a waterway,  the Danube also is called home by many species of plant and animal life.  This plant and animal life is also referred to as the flora and fauna, respectively.  The Danube River basin is the longest marshland in Europe.  It contains the greatest stretch of reedbeds in the world.  In fact, these plants dominate the plant life of this marsh.  In the delta, 1,700 sq. kilometers is covered with reedbeds.  This only leaves about 150 sq. kilometers that is not covered by reedbeds.

Reedbeds are not the only type of vegetation found along the Danube River.  There are many different species of water lilies.  Sandy areas along the river are covered with a grass called Stippa.  There are also many forests along the Danube.  They all contain their own plant life as well.  In the Letea Forest, there are dunes that are 250 meters wide and 10 meters long.  There are trees coupled in with these dunes that reach the height of 35 meters.  This forest is also home to many rare species of plant life.

There are also many different types of animal life.  There are over 300 species of birds.  A large percentage of the world wide population of these species live in area of the Danube basin.  The Danube delta is a very important area for fish.  Over 45 species of freshwater fish live in the lakes formed by the delta.  One of these species, the Acipensednidae, is endangered.

Souhegan River, NH
10 years ago

Unlike the mighty, I would like to point out the Souhegan River which is 32 miles long that at different times has had a total of more than 15 present and former dam sites. These dams were used for water power and later for generation of electricity. 

The river is an excellant place to white water in the spring, and in other sections enjoy a meandering stream.  To our area it is a great resouce and has been throughout history.

The NH legislature voted to classify the Souhegan River as a designated river.

So, I will rate it a river of the world!

St. Lawrence River

From the heart of a continent to the coast of an ocean, from sweet water seas to salt water shores, the course of the mighty St. Lawrence River is also the course of Canadian history.

Avenue of exploration, corridor of commerce, cradle of New France and Upper Canada, the great inland waterway of the northeast was destined to lead not to the spices and silks of China, but to the even greater bounty of forests, furs and raw materials. Carved between the Laurentians to the north and the Appalachians to the south, and forming a natural pathway to the lakes of Ontario, Erie, Huron, Michigan and Superior, the river seems almost purposefully designed for navigation. Where Mother Nature has stood in the way - stirring in rapids up above, or billowing thick, treacherous fog down below - mankind has cleverly side-stepped Her, damming, diverting, dredging and ultimately designing the St. Lawrence Seaway, one of the greatest river transportation systems in the world. Fed by the Great Lakes, draining a million square kilometres, beginning in the freshwater bays of eastern Ontario's Thousand Islands, and running nearly 1,200 kilometres, to the saltwater shores of Anticosti Island and the tip of the Gaspé Peninsula, the river is known simply as "Le Fleuve" - the Greatest Canadian River.

Approximately 800 miles (1,287 km) long, the St. Lawrence River can be divided into three broad sections: the freshwater river, which extends from Lake Ontario to just outside the city of Quebec; the St. Lawrence estuary, which extends from Quebec to Anticosti Island; and the Gulf of St. Lawrence, which leads into the Atlantic Ocean.
