Soon bureaucrats came together to create the Colorado River Project, wanting to create a series of dams along the Colorado River to create hydroelectric power and serve to control floods and droughts. With Buchanan dam well under way with a total of six planned Marshall Ford was the only dam designed primarily for flood control and the only dam in which USBR oversaw construction. With money scarce there was debate over the final height dam and it reservoir capacity. This issue resolves itself with the flood of 1938. Once completed Marshall Ford Dam would flood 65 miles of the Colorado to form Lake Travis, creating the largest of the seven reservoirs known as the Highland Lakes.
Measured along the river, the canyon is 277 river miles or 443 kilometers. The Grand Canyon has a width of 600 feet to 18 miles at its widest point. Lastly, the depth of the Grand Canyon is one mile or 1.6 kilometers. It is carved into a series of elevated plateaus in northern Arizona and has been shaped by erosion and the Colorado River. The canyon is unique both in scenery and the variety of exposed geological features.
Discussions in this paper will include a general history and how the American Southwest relies on the Colorado River for survival, how climate change is effecting it, and management efforts to curtail conflicts between vying interests over a shared water source. Figure 1. Map of the Colorado River THE COLORADO RIVER The Colorado River is located in the southwestern United States and northwestern Mexico. It is 1,450 miles long with its headwaters in the Rocky Mountain National Park in Estes Park, Colorado. Geologically, the Colorado River begins near Moab, Utah, at the junction of the Green River,which is the primary tributary for the Colorado.
Arizona is composed of 1 billion tons of rock. The Grand Canyon stretches 18 miles across and 277 miles long and more then a mile deep. It is so vast that is even seen from space. The river is 1450 miles long and 800 million gallons of water for every hour. The first day of this trip we will be rafting down the Colorado river starting from central Colorado with the “Ava Live the Day Company.” Now let me give you some history on who was the first rafter of this great river that formed the canyon.
Major cities such as Las Vegas, Los Angeles, San Diego, and other communities in the southwest depend on the river. It provides water for over 20 million people, irrigation for 2 million acres of land, four thousand megawatts of hydroelectric energy, and over twenty million annual visitors for recreation purposes. Also, once in Mexico, the river provides water to irrigate half a million acres of farmland, and municipal and industrial water for 2 million people living in this delta region. The river distributes its flow from lakes and canals along its journey as well. Due to climate change, human demand, natural forces like evaporation and human-induced climate change this water supply is in conflict.
Irrigation is the artificial supply of water to the land, an integral part of the Colorado River and its basin. More than 1,500 years ago, the Hohokam irrigated more than 200,00... ... middle of paper ... ...g Colorado River will demand congressional action. N.p., n.d. Web. 14 Apr.

Further, the absence of silt down stream would have two dramatic effects: ? Some hydrologists think that this could make downstream riverbanks more vulnerable to flooding.  ? The city of Shanghai, more than one thousand miles (1600 km) away from the dam, rests on a massive plain of sediment.
I traveled all the way from Pennsylvania to run these rivers, how could I back out now? I had to run Sunshine Falls...the largest rapid on the Royal Gorge section of the Arkansas River. When would I make it back to Colorado to run this river? I considered the the portage again; it's an impressive drop with no shame in walking. But what if they dam the Arkansas?
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.
The water in Colorado is just that; Colorado’s water, owned by the people and restricted by the state. However, Colorado is required by law to send over 30 million acre – feet of water to seven western states (“Missouri River”). An acre – foot is “The quantity of water required to fill one acre with one foot of water and is equivalent to 43,560 cubic feet or 325,850 gallons” (“Missouri River”). The State enforces all water laws in Colorado even though they are not straightforward and are riddled with loopholes. These water laws came into effect “As early as 1879” (Hundley, Jr. 53).
