Some additional water vapor is provided from evaporation on the land from lakes and rivers and from transpiration from plants. The precipitation that falls on the land provides needed water to plants and then either goes to ground water aquifers or into lakes and rivers. Once fresh water finds its way into rivers, it will eventually flow back into the oceans where the water cycle begins again. Rivers Wildlife and fish depend on rivers as do a number of cities for drinking water and businesses for use in manufacturing processes. The Cuyahoga River Rivers are generally not simple to describe.
Rivers occur where there is water and gravity.
They are complex and wear a number of identities depending on whether or not they are winding through a natural forest or between two factories or along the variety of uses in between. The history of the Cuyahoga is documented in this film through a series of drawings and photographs from its use by Native Americans through its use in the discovery of the Western US and its role in the canal systems. The canal system no longer exists, but there are remnants of it that are still visible today. The Cuyahoga River was important to the economic development of the Cuyahoga Valley. By the 1960s, the Cuyahoga was a sewer.
