Humans have lived around the Colorado River basin for thousands of years. The river was first noted in documents in 1539 and first given the name Colorado in 1743 ("Geography of the Colorado River"). During the 1800s and 1900s explorations of the river took place and in 1921 it was reamed from the Grand River to the Colorado River ("Geography of the Colorado River"). The flow of the Colorado River has created many canyons. One of the most notable canyons that have been created is the Grand Canyon. The river’s uses include power generation, irrigation, municipal, industrial use, flood control, and recreation. This water is used by people in the areas surrounding the river as the water is diverted for their use. Some of the politics su...

...groundwater collections (“Water Returns to the Dry Colorado River”). Pulse flow leads to the rehabilitation of the river bed and the increase in water level.
The largest water quality issue of the Colorado River is salinity and selenium (“Water Availability: A Matter of Quantity, Quality and Use”). These issues pose long term threats such as water availability, plant growth and crop yield effects, infrastructure damage, water quality reduction, and taste and odor concerns (“Water Availability: A Matter of Quantity, Quality and Use”). To reduce this problem, federal agencies and the Colorado Basin States are working together in order to put salinity control projects into place to reduce the amount of salt entering the river; this process is said to save economic damages by about $100 million per year (“Water Availability: A Matter of Quantity, Quality and Use”).

- The Colorado River is the seventh longest river. In the 1920’s Western states began dividing up the water in the Colorado River by building dams and divert river flow to San Diego, Phoenix, and other large cities in order to supply water to these cities. In the past the river has been known for being a major source of water and electricity. The Colorado River passes through Utah, Arizona, Colorado, Nevada, California, Baja California, and Sonora. During the past decade a drought has been sweeping the Southwest resulting in a lowered river level.... [tags: history, grand river, aqueduct]

- One of the largest geographic physical structures in the United States is the Colorado River. Human activity and its interaction with this great river have an interesting history. The resources provided by the river have been used by humans, and caused conflict for human populations as well. One of these conflicts is water distribution, and the effects drought conditions have played in this distribution throughout the southwestern region. Major cities such as Las Vegas, Los Angeles, San Diego, and other communities in the southwest depend on the river.... [tags: Geography, Physical Structure, United States]

- The Colorado River, once a river full of silt and raw energy is now a river of clear blue and harnessed power. There was only one thought that crossed my mind as I watched this film; was damming worth it. Was damming worth the violent deformation of some of the world’s most renowned natural formations. This quandary affected more than just the beautiful Colorado River. The Columbia River, which runs through the Pacific Northwest and lower parts of Canada, is a stunning river. It once had, according to National Geographic, “as much as 43 million pounds (20 million kilograms) of salmon and steelhead a year,” from just one outflow; juxtaposed to today where there are roughly only “2 million p...

- The Colorado RIver is best known for being the principal river of the southern United States and Mexico, but it soon could lose that title. Running about 1,500 miles long, the river is a vital source of water for agricultural and urban areas in the southern desert lands of North America. However over the past decade or so, the river has begun to deteriorate. There are many causes and solutions to the deterioration of the Colorado River. The Colorado River is formed by small streams created by a huge amount of snowmelt from the Rocky Mountains.... [tags: agriculture, salinity, flows]

- INTRODUCTION According to tree ring scientists from the University of Arizona in Tuscon, the Colorado River went through a six decade long drought during the mid-1100s. This drought was longer than any other drought know to the region. The Colorado River is essential to the American Southwest, draining into about 242,000 square miles of land to include seven U.S. states: Arizona, California, Colorado, Nevada, New Mexico, Utah, and Wyoming. “The Intergovernmental Panel on Climate Change predicted in a recent report that the Southwestern U.S....

- Prior to settlement of the western United States, the Colorado River roamed free. Starting from cool mountain streams, the river eventually became a thunderous, silty force of nature as it entered the canyons along its path. The river nourished wetlands and other riparian habitats from the headwaters in the Rocky Mountains to the delta at the Sea of Cortez in Northwest Mexico. Settlers along the river harnessed these waters mainly for agriculture via irrigation canals, but flooding from spring runoff wreaked havoc on agricultural land, prevented development in the floodplain and full utilization of the water, a waste in the eyes of western farmers....

- In the World, the liquid medium that we know as water is the main component that keeps humans, animals and their respective ecosystems alive. Everything from trees down to the smallest leaf requires it, and it is required for any lifeform to continue to grow. Though as humanity expands and continues on an upward slope, humans as a lifeforce continue to need more. Water is a defining aspect of a community, and with the ever-rising population and human-crafted climate change coming to an all-time high, one of the most important water origins of the southeast region is coming to a very dangerous low....
