Water Management of Murray Darling Basin
Local and downstream component of water recovery
The Basin Plan achieve to reduction of SDL as two separate parts which are a local and downstream. A local part focus on environmental needs within each catchment, and downstream also considers the health of the Basin major trunk rivers which are the Barwon and Murray Darling from the north to south.
However, the downstream component of water recovery should be allocated between equitable, catchment in a consistent and transparent manner by 971 GL in the southern basin and 143 GL in the northern Basin. Governments have agreed that the shared downstream component in the southern will be apportioned between states on their share of surface water diversion, also has agreed that each state will determine the apportionment of its share of downstream component to catchments within their state. An initial apportionment of downstream component will be advised by each state and with final apportionment will be followed the SDL adjustment mechanism to be reviewed the strategy for further updated in 2016.
On the other hand, governments have agreed to establish a program of work to be completed by the end of 2015 to review the basis to downstream component and it’s equitable in the northern Basin. This work program which also calls Northern Basin Scientific Work Program considers the impacts of northern basin downstream component on the anticipated environmental outcomes of the recovery. The program will be updated in 2016 to reflect the outcome of work.

Environmental works and Measures
Supply measures can help delivery water more effectively and efficiently as environmental works and measures. The Living Murray program was the one of environmental and measures project in the past, and governments have invested around $287 million works to manage and delivery environmental water of the Living Murray ‘icon sites’. Investigation of new environmental works and measures is provided by the governments such as removal of impediments to environmental flows, building regulators to deliver environmental water to wetlands and purchasing flood easements.
In addition the Basin states have processing to identify the environmental works and measures as prefeasibility studies in their community, and 17 feasibility studies-projects are still on the way.

For almost two centuries the TSW, in dealing with public pressure, has pointed to its original mandate. The concern is that in doing so it fails to recognize that increasingly, the entire waterway is an expanding recreation base, which not only requires water for navigation but also requires an equitable supply of water to support recreational uses and to maintain and enhance the natural environment. The TSW, although maintaining their original position, has over the years made provision for “new” uses of water including diverting vast amounts to white water canoeing events, water filtrations plants and increased municipal uses. Clearly times have changed and the TSW must recognize that it must adapt through not only a change of mandate but also a change of governance that would recognize and better co-ordinate the vast amount of stakeholders within the system.
The process of collaboration began with these meetings which evolved into more formal discussions on water allocation (Gosnell and Kelly 2010) The KBRA does not establish water rights, but it is a formal agreement on how water will be allocated when there is sufficient flow to meet the terms of the agreement. As it pertains to the wildlife refuges; the KBRA requires 48,000 to 60,00 acre feet in the summer months and 35,000 acre feet to go to Lower Klamath NWR in the winter period which includes allocations to cooperative farmland. The agreement allocates 13,000 acres of wetlands and open water to Tule Lake NWR, which includes cooperative farming land on the refuge(Klamath Basin Restoration Agreement 2010).As the KBRA cannot legally create a water right, delivers are contingent upon the total available water in the basin. If there is a water deficit of more than 20,000 acre feet no water is allocated to the refuges during the summer months. In terms of refuge farming the KBRA refers to the Kuchel Act of 1964. If the KBRA is not renewed the refuges will not be given any water and both bird and farmers will live in uncertainty. It is likely that other more informal agreements may be negotiated between groups, but none as binding or inclusive as the
The Colorado River Delta is a vast stream of water that begins in the Rocky Mountains and flows to the Gulf of California. It is the primary source of water for the western part of the United States, making the golden nectar available to Arizona, California, Colorado, Nevada, Utah, and Mexico. Because of miscellaneous international treaties and over 40 dams built along the river’s path (Ficklin 1), it is slowly becoming the most controlled of all watersheds. With the populations of these towns becoming greater, the amount of pull on the river from the society has increased as a rapid rate. Normally that would not be a problem but given the context, water sources are not as dynamic--fluid, if you will, as the world would often appreciate.
The Murrumbidgee River is the 3rd longest river in Australia and in the Murray–Darling Basin (MDB), after the Murray and Darling rivers. The area of catchment is 8% of the total area of the MDB Basin and provides almost 16% of inflow for the Basin (Burrell, 2017). In Murrumbidgee regulated river, water source is defined as the water between the banks of all rivers, from the upper limit of Burrinjuck Dam water storage (being the Taemas Bridge crossing) and Blowering Dam water storage (being the dam wall and spillway for Jounama Pondage), downstream to the junction of the Murrumbidgee River and the Murray River
The system on a whole has been affected as the surrounding Coorong and Lower Lakes areas are encountering declining environmental conditions including: degradation of swamps, receding riverbanks and irrigation banks, disruption of irrigation usage and the irregularity of ferry services. These environmental issues have an effect on the provision of portable water to Adelaide and regional towns who rely on this water source. This means the government is having to find other sources of water so that it can be provided to Adelaide and the regional towns, putting extra stress on the

This means that economic and political interests are not limited to one state. However, I believe the states with the most at stake are the lower basin states. Since California, Arizona and Nevada’s combined populations are larger than that of the upper basin states, we could assume that the need for water in these areas is greater, on account of the individual populations. However, upon reading the textbook and articles about the splitting of the Colorado River, it seems that the portions for each state remain unbalanced. When the Colorado River compact was signed in 1923, the ratio of water to water usage was severely overestimated. This issue continues to be relevant today because of this same principle. With that said, every state has some degree of interest in this water. The river water plays a role in each state’s social and economic
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...
“Water is the driving force of all nature.” Leonardo da Vince once said. Water is a huge part of life, and everything that lives requires water to make it through its days on earth. A lot of people think that the world has massive amounts of water available for use; therefore, most roll their eyes when conserving water is mentioned. After all, 71% of the earth’s surface is made up of water. However, the truth is that only 2.5% of that is clean, drinkable water, and two-thirds of that percentage is unavailable because it is stuck in ice caps and glaciers (water). The water ordeal in America is bigger than many realize, and the United States needs to begin looking at how we can solve this issue. The U.S. needs to acknowledge the impending dangers and help the states that are already suffering by putting water conservation methods in place and investing money into research for alternatives.
Since water is becomes such a sought after resource, steps need to be taken on the sustainable/conservation front. The authors in “A Sustainable Decision Support Framework for Urban Water Management“(Pearson) say that three main ideals need to be the basis for sustainable decision making “1. Knowledge transfer for transformation; 2. Monitoring and evaluation of the decision process; and 3. Stakeholder engagement.” (Pearson). These ideals make sense because within each step the knowledge of sustainability is increasing. A sustainable water infrastructure will be much easier to accomplish if the public opinion supports sustainable practices. With overwhelming public support, bills and regulations can pass with less

Irrigation consumes about 60% of all fresh water. (Perlman, H.2010) The large underground natural aquifer Ogallala in Nebraska, supplying with water all 1/5 of the irrigated earths of the country, becomes empty with speed of 12 billion cubic meters in a year. In comparison with initial volumes the aquifer has already lost a quantity of water equal to 18 rivers Colorado. Now farmers of Nebraska, Kansas, and Colorado and of some other states are compelled to refuse the harvest demanding irrigation. Under forecasts of experts the next 20 years 40 percent of the Earths irrigated with water from Ogallala will cease to be cultivated.
