Water Supply In The Southwest: A Case Study

The Central Valley Project (CVP) is a Federal water project set up and run by the US Bureau of Reclamation to provide water for the Central Valley in California. Through twenty dams and reservoirs the CVP facilitates the collection and delivery of water for irrigation, municipal, and industrial use, as well as producing hydropower, providing flood control and recreational facilities on their reservoirs. The CVP provide a good example of how cost allocation works within a vast organization. I will use this organization to describe the method used by the CVP to allocate cost and whether I agree or disagree with their methods. I will also be identifying situations where common costs are allocated. I will explain the impact of allocating

I.) Water and Drought in California: Facts and data show that the weather we are experiencing here in California is that there is a difference between La Niña that brings the ocean temperature down and making them cooler and El Niño brings much warmer ocean temperatures. Currently california is experiencing a weakened La Niña. With a 55% chance of this weather continuing for the next 3 months. La Niña affect patterns of rainfall, atmospheric pressure, and global atmospheric circulation. Even though California is in a severe drought, with coordination, modernization, and compromise, California should be able to provide enough water for a growing population and growing economy.

Due to the decline of the water levels in Lake mead and Colorado River, this has a huge impact on the the southwest of Arizona. This hugely impacts the agricultural industries and ranchings because they face drought, scouring heat and water shortages which decreases their farms yields and productivity. Because Arizona farmers are dependent on irrigation for vegetation, with a water crisis they would have feed shortages which would cause them to sell their farms with weaker disaster relief support.

In his book, Cadillac Desert: The American West and Its Disappearing Water, Marc Reisner’s main thesis is to show the inefficiency, greed, and inherent difficulty in the American West’s never-ending struggle to turn its unwelcoming desert into a lush garden. One of his main sub-points is that the West is not meant to support millions of people. It has a wide range of geographic challenges throughout the entire region. Its inconsistency and diversity is a primary cause of its water problems. For example, Reisner notes that the West consists of “plains so arid that they could barely support bunchgrass; deserts that were fiercely hot and fiercely cold; streams that flooded a few weeks each year and went dry the rest; forests with trees so large it might take days to bring one down; . . . hail followed by drought followed by hail;” (23).

A potential solution for farmers would be to switch to a subsurface drip irrigation system that could permanently cut farmers' water use by 25 to 50 percent. This would alleviate some of the need for conservation and free up more state water reserves for urban use during time of regional drought (U.S. Water News Online).

The State of Colorado has suffered from a water shortage in recent years; a difficult situation which is easily visible when viewing the quickly shortening length of the Colorado River. Lake Mead, for example, is roughly 130 feet lower than it once was, marked by the stained rock which towers above the current water level. “The river has become a perfect symbol of what happens when we ask too much of a limited resource: it disappears. In fact, the Colorado no longer regularly reaches the sea” (Zielinski, 2010). Legislation was implemented early on to address this issue, though the results were (perhaps not surprisingly) rather unanticipated, regarding

Drought condition exists throughout most of Arizona. Variable amounts of rainfall throughout last year’s where was significantly below the normal with surface water flows, reservoir levels, and well water pumping levels are at some of their lowest ever recorded all of that act as indication of drought occurrence. Drought is a normal recurring feature of climate, not a rare or random event. Climate influence water quality throughout temperature, precipitation, and wind by affecting the physical, chemical, and biological characteristics of water. For instance, temperature fluctuation results in more stress on aquatic organism within water body, in the same way wind fluctuation has a direct effect on evaporation rate. Municipal water providers in Flagstaff, Williams, Mayer, Pine, Strawberry, and in areas near Sierra Vista, Sonoita, and Picacho have suffered from some potable

The Dust Bowl drought was the worst in U.S. history that was around 1930. It was in the mid west where it covered sixty percent of the country. Millions of people had to move to other parts because it lasted four years. It was "at its peak in 1934" according to "National Climate Data Center". We already have a lot of drought in California and west although one might say it is all of the U.S. With little rain and high tempatures in the summers drys out the vegatation which become a hazard for fires. Global warming might have some to do with the problem of drought. High populations need more water, with more water being used, depletes resources of water supplies which causes drought also. People need to become more aware of the use of the use of water, a lot of people take it for granite that there is plenty out there for all of us to share. In fact, if we don't start to conserve, we might not have water like we do in the future.

Since 1990 Texas has seen a trend towards warmer and drier summers than usual. Texas which geographically sits in the south central part of the United States with an extensive border with the Gulf of Mexico gets its weather patterns from both the Atlantic and Pacific Oceans. Researchers have shown that warmer than normal temperatures in the Atlantic and Pacific Oceans often lead to drier than normal summers. The research also shows that these trends will last for more than 20 to 25 years. Since we have been in this weather pattern since 1990, (Hembreee), hopefully we are nearing the end of the dry cycle. However, Mother Nature is never predictable. Meteorologists are only able to speculate about a week in advanced with any certainty. The eastern Pacific Ocean cycles between three phases, the three phases are El Nino, La Nina, and Neutral phase. La Nina is cooling of the sea-surface temperatures and tends to bring more rain into the Gulf of Mexico and Texas. On the opposite

Due to the lack of rain in the past few years, and particularly in the last few months, California faces severe drought. This is the worst drought in more than one hundred years. The impact of California drought affects community, agriculture, organic ranchers, and dairy farmers. Because of these facts, the United States must rethink the way it uses water. Californians alone are asked to reduce their water usage by twenty percent to prevent water waste.

California has always had a warm climate, yet its supply of water has rarely been affected. In 2014 California’s water shortage issue truly began. Due to low amounts of snow in the winter in recent years, California has tried to equal out these shortages by drilling water from underground aquifers. Yet, underground aquifers recharge much slower than surface water sources. California has already made significant drawbacks to attempt to limit the amount of water they use, so these aquifers can recharge. But still resources continue going down and the Central Valley Aquifer’s water level is rapidly declining. Luckily, on April 7, 2017 the drought stage of emergency in California was ended. Yet the issue isn’t truly resolved. Glen MacDonald

In my opinion, the affordable water solution includes two main directions: Taps new resource and reduces expenses of water. There are many ways to create the new water resource and the feasible methods are 1. Building desalination plants 2. Building new the dams 3. Rain harvesting system. California has very long coastline and it provides the very great opportunity to utilize sea water to generate drinking water by desalination plants. NBC news “Solutions to California's Water Crisis from Half a World Away” showed the interesting comparing data between California and Israel in table 1 [2]. The desalination plants will contribute large amount of water to California’s drought. We need to consider if low snowpack and high temperature will happen frequently in the future, this is a right time to make a foresight plan to build the desalination plants. If the weather is still drought, agriculture must pump more water away from aquifer. There is not only the land is sinking but also influence the eco system.

Most of us consider drought as a period of dry and hot weather with too little or no rain, and while any or all of these conditions might be existent during drought, the definition of drought is more complex and subtle. According to the United States Geological Survey, California Water Science Center (as cited in Congressional Digest, 2015, p. 2):

In today’s society, the idea of a limited resource is not a foreign concept. Most people understand that eventually humans will use up many of these resources, such as fossil fuels, and they will cease to exist. However, very rarely does a conversation about limited resources get started over the water. While water itself is not a limited resource, clean drinkable water is becoming scarcer as people continue to use excess water. The documentary “Last Call at the Oasis” highlights how precious water is to survival and just how much miss use of water occurs in the United States alone. Even though the United States has gone down the wrong path with its water consumption methods, it may not be too late to recover. With the proper systems and education in place, the chances of delaying a water crisis increase exponentially.

In the United States, the available water resources is also under assault. Half of water collected and stored by existing infrastructure is usually used in the production of electricity. This forces the population to use and divide what little there is left. This has always been a “good enough” approach until now, when water prices and population is on the rise.(3) There are already calls for charging water resources in order to increase efficiency of use.(3) Water protection is already being carried out and has been for years, but there is still water pollution occurring within the United States. After the Civil war, America strived to provide its population with clean water
