On the landscape, freshwater is stored in rivers, lakes, reservoirs, and creeks and streams. They were our first highways, bringing explorers into the heart of the continent. All rivers and streams start at some high point. River-based irrigation permitted communities to specialize and develop, even in areas lacking adequate rainfall. Rivers provide us with food, energy, recreation, transportation routes, and of course water for irrigation and for drinking. Rivers provide our communities with economic, ecological, and cultural value. Rivers are useful for us in many ways - Water Rivers carry water and nutrients to areas all around the earth. Water from some source like a spring, snow melt or a lake starts at this high point and begins to flow down to lower points. People use rivers for transportation and as a source of natural resources. Invertebrates have no backbone or spinal column and include crayfish, snails, limpets, clams and mussels found in rivers. Fast-flowing rivers carry pebbles, sand, and silt.

When dams are built, these subsistence fisheries are often flooded out, forcing people to move away and find other work. From there to Cairo a 4-m-deep (12-ft) channel is maintained. A large number of the invertebrates in river systems are insects. The National Wild and Scenic Rivers System has only 13,413 river miles in it—less than one half of one percent of our rivers are protected through this designation. People also harvest fish, shellfish, mollusks, ducks and other food animals from rivers. The lower river, which has a relatively narrow but deep channel, is navigable for oceangoing ships upstream to Baton Rouge, La. Rivers can also form what is called an estuary, where salty seawater mixes with fresh water near the river mouth to form “brackish water.” The Hudson River in New York, U.S., is an example of an estuary where brackish water extends more than 241 kilometers (150 miles) upstream. They play a very important part in the water cycle, acting as drainage channels for surface water. Currently, 600,000-750,000 miles of our rivers lie behind an estimated 75,000 dams. For those cultures that depended on them, rivers were the lifeblood. In 1985, the number of large dams was thought to be 60,000.
