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. Will become hotter and drier as the climate warms.” With human caused climate change and run off reduction, it has been predicted that the Colorado River could become dry by 2012. 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.

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. (Until 1921, the Colorado River did not “technically” begin until the Grand and Green Rivers joined together in Utah. In that year the Grand River was renamed as the Colorado River, at the request of the State of Colorado.) It then flows south out of Wyoming, and the Grand River, and southwest out of Colorado. Below this point, the river takes on a redd...

Colorado River Hydrosphere A case study of * River management * People interfering in the hydrosphere * Balancing water from one area to another The Colorado river - basic facts It flows through southwest United States and northwestern Mexico. It is 2334 km (1450 miles long), the longest river west of the Rocky Mountains. Its source is west of the Rocky Mountains which is the watershed in northern Colorado, and, for the first 1600km (1000miles) of its course, passes through a series of deep gorges and canyons that were created by the eroding force of its current. The river flows in a generally southwestern direction across Colorado into south eastern Utah, where it is joined by its chief tributary, The Green River. After crossing the northern portion of Arizona, the Colorado flows west for 436 km (271 miles) through the majestic Grand Canyon.
Lake-Effect snow has a range of different intensities depending upon certain factors. The difference between the air temperature and the water temperature will determine how much moisture is taken into the air. Warmer water and colder air makes for more snow. Also the distance the air has to travel across the lake will determine how much moisture the air is able to obtain. The ability of the storm to travel inland will be determined by the intensity of the storm’s winds. Storms also are able travel farther inland in late fall and early winter.

Water has long been a controversy in countless places worldwide and Colorado is no exception. The water rights in Colorado involve different stages within the Prior Appropriation Law; the senior and junior water rights. Senior water rights are privileges that were the first to be issued on unappropriated streams in Colorado and are to be filled before the junior water right holders. Junior water rights are similar to senior water rights, but are filled after the senior water holders take their allotted amount (Wolfe Prior Appropriation Law). 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). In the laws, there are even more constraints and idiosyncrasies including; owning ground water, owning surface water, senior rights and junior rights, and the use and reuse of rainwater or graywater. Water users in Colorado need to familiarize themselves with the laws and regulations involving water in order to receive the allotted water and the reasoning behind that number.
The prospect of Lake Mead’s water level returning to the fullness of the past would be a desirable outlook. As stated, “Snowpack in southern and eastern Oregon, California, Arizona, New Mexico and Nevada is still far below normal” (Berwyn, B., 2014, para. 3). The very dry conditions in New Mexico, Arizona, and Southern Nevada muc...

As global temperatures and ocean levels rise, the water levels of the Great Lakes continues to fall. As the lakes hit their all time lowest level in global history in 2012, society remains ignorant to the imposing doom that lurks ahead. Since the Great Lakes make up the largest group of fresh water lakes on Earth and are responsible for approximately 21% of the Earth’s fresh water supply, this issue is becoming one of the largest environmental and economical issues our modern world faces. The effects of this issue include destroying animal habitats and a major economic market; shipping. Water levels in the Great Lakes have been dropping for the past fourteen years, but it wasn’t until boats were scraping the bottom of Lake Huron that people began to take notice. This terrible environmental issue has been dubbed a long term cycle of over evaporation and not enough precipitation to replenish the Lakes. Keith Kompoltowicz, chief of watershed hydrology for the United States Army Corps of Engineers in Detroit has been monitoring this issue for a decade and has made startling discoveries, such as in 2012, he discovered Lake Michigan and Lake Huron’s water levels only rose four inches after winter, whereas the Lakes have been regularly recorded as gaining a foot of water after the winter season had ended. This amount of water added is not enough to maintain a proper water level during the dry, hot summer seasons that evaporate much water from the Great Lakes. While some scientists say that this is just a cycle that will adjust itself naturally, most experts that have been studying this phenomenon, such as Kompoltwicz, would agree that the issue has gone to far
With the changes coming from global warming and increased greenhouse gasses, there will be many impacts to Texas over the coming decades. One of these impacts is the effect on our water resources. Texas’ main source of fresh water is precipitation, coming almost completely from rainfall. With temperatures rising and with an expectation that precipitation levels will most likely drop in coming years, this combination will put great stress on our water reservoirs. If we continue our current usage rates of water and if recent climate changes continue to persist then we will see a huge decrease in our water reservoirs. Also, given that we are in a drought, it appears that conditions are getting worse every year, posing a serious problem for the future if this issue is not addressed now.
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.

Americans today tend to believe that the Colorado River drought has been a recent occurrence, although drought relief strategies have been implemented since early 1997. To summarize, in the book The Colorado River Basin Drought Planning and Organizations, Colorado is named as the original state to acquire a drought relief plan. For instance, various assume water levels are diminutive in the Colorado and blame is due to the previous ten years of drought throughout the United States. Although it is true that water levels are at a record low, initial plans in the early 1920’s to introduce manufactured structures into the water basin is the original reason Colorado’s water system began to be compromised. It follows, then the supplementary natural
The Colorado River, which has so many uses and serves so many, is running out of water. The river delivers water and power to nearly 30 million people who live in the basin states. (River Uses) That includes people who live in Colorado, Arizona, Nevada, New Mexico, Utah, California, Wyoming and Mexico. In addition, the river is crucial to the economy because “throughout the seven basin states, the Colorado River provides water for people and for business and industry - creating jobs for millions, jobs that contribute to local economies and billions of dollars to the nation.” (River Uses) The river is also important as it provides irrigation to about 1.4 million acres of land for fa...
