Lake Havasu is the deepest, behind Parker Dam.

Mt Mckinley has the greatest rise from surrounding plain to peak, I think.  Mt Everest is the highest.

The Ogallala aquifer located in the midwestern United States is believed to be the world's largest aquifer.\n\nThis aquifer is named after a Sioux Indian tribe. It is estimated to be more than two million years old and to hold about 650 trillion gallons (2,500 trillion liters)! It underlies parts of eight states, stretching about 800 miles (1,288 km) from South Dakota to\nTexas. The Ogallala aquifer supplies vast amounts of water to irrigate the crops in this vitally important agricultural area.\n\nThe Guaraní Aquifer System (GAS), perhaps, is the world’s second largest fresh groundwater reservoirs, due to its extent and volume. It underlies portions of Argentina, Brazil, Paraguay and Uruguay, stretching over an area of approximately 1.2 million km2, with almost 15 million inhabitants. The capacity of the GAS is estimated at around 40,000 km3.

Define large, then define the application. Is it for potable water?\n\nWithout knowing more, here are some ideas:\n1. Steel, fiberglass, or metal alloy tank.\n2. Dirt (Pond, dam, reservoir)\n3. Plastic or plastic composites\n\nWithout knowing the application, restrictions, size, and other data, it is hard to pin down what is feasible.

Dam, known as Marib dam, is one of the most ancient dams in the world.  I believe that the dam was rebuilt by USSR or USA funding within the last 20 years, but the more ancient part was preserved. \nEven if the whole dam was preserved, the resvoir would not be incredibly large. The dam collects runoff water from rain, and as it is well known, it does not rain that much.

Dallas and Ft. Worth both obtain their water supplies from several different Corp of Engineers lakes in north Texas.  Lake Lewisville, Lake Benbrook, Lake Ray Hubbard, Lake Fork, etc;  The metroplex is very large in terms of population and geographically.  One lake (or reservoir) could never supply the needs of that many people spread over such a large area.\n   Recently, a giant lake was planned for Anderson County, east of Dallas, but, the government decided that it would become a federally protected wetlands and nature conservancy of almost 25,000 acres instead.  Water supplies will continue to be problematic for the north Texas region well into the next century.  This last move by the clueless congress did not help matters.

For thousands of years the Nile River overflowed its banks every spring as the snow in the mountains transformed into a torrent of water. The annual floods carried dead and decaying plants in its muddy solution. The muddy water is called silt, and silt creates excellent farmland. \n\nSince 1970, the Aswan Dam has controlled the annual flood. By holding back water, the Aswan Dam created the world’s largest man-made lake: Lake Nassar. The water from Lake Nassar provided new fishing areas and provides much needed water for agriculture. The Aswan Dam also makes it possible to grow an extra crop each year by holding back the summer flood that covers the banks of the Nile River. \n\nCritics charge that building the Aswan Dam was unwise. The project was far more expensive than expected. Further, the annual floods carried silt, which created the topsoil needed for plants. Since the creation of the Aswan Dam, the farms on the formerly flooded banks have had to use expensive fertilizers in place of the silt. Formerly, fish have fed on the silt, and the people downstream depended on fishing from the river.

The Aswan High Dam is 3,600 m in length, 980 m wide at the base, 40 m wide at the crest and 111 m tall. It contains 43 million m³ of material. At maximum, 11,000 m³ of water can pass through the dam every second. There are further emergency spillways for an extra 5000 m³ per second and the Toshka Canal links the reservoir to the Toshka Depression. The reservoir, named Lake Nasser, is 550 km long and 35 km at its widest with a surface area of 5,250 km² and holds 132 km³.\n\nThe dam powers twelve generators each rated at 175 megawatts, producing a hydroelectric output of 2.1 gigawatts. Power generation began in 1967. When the dam first reached peak output it produced around half of Egypt's entire electricity production (about 15% by 1998) and allowed for the connection of most Egyptian villages to electricity for the first time. The effects of dangerous floods in 1964 and 1973 and of threatening droughts in 1972–73 and 1983–84 were mitigated. A new fishing industry has been created around Lake Nasser, though it is struggling due to its distance from any significant markets.\n\n\nYou can see some of the details in the following link

i haven't done this in a while.\n\nThe volume of the reservoir is equal to (1/2)*(height)*("base")*length.  the reservoir is a rectangular prism with the "base" being the distance across the surface of the water.  We are given the shape of the full volume so we can scale down to the level of the water to find what the volume in the reservoir at its current level.\n\nif you think about the cross-section of the volume, and use half of that forming a right triangle, we can determine the ratio of the surface (the "base") to the height (water depth).  In this case, it is (40/2)/(20*sqrt(3)) or 1/sqrt(3).  so ("base"/2)/(height) = 1/sqrt(3)  and then "base" = (2*height)/sqrt(3).\n\nsubstitute that into the volume equation so that\nvolume = [(height^2)*length]/sqrt(3) or literally,\nV = [(h^2)*L]/sqrt(3).  differentiate with respect to time,\n(dV/dt) = [2*h*(dh/dt)*L]/sqrt(3) and substitute the numbers in:\ndV/dt = 200 - 50 = 150\nh = 10*sqrt(3)\nL = 450\nand solve for dh/dt which is the rate of change of the water level in yds/hour.  these are odd units, you might want to change to inches/hour.\n\ni did it this way and got 1/60 yds/hr or 0.6 inches/hr.\n\nbut again it has been a long time....

efficient use of under ground water\n\nEngineering Practices\nWater Reuse and Recycling\n\nLand irrigation methods\nInstall irrigation devices that are the most water efficient for each use. Micro and drip irrigation and soaker hoses are examples of water efficient irrigation methods.\n\nPlant it smart. Xeriscape landscaping is a great way to design, install and maintain both your plants and irrigation system. More importantly, it will save time, money and water.\n\nLeakage/Loss Control
