The low flow curve represents the diffuse void flow, the intermediate curve indicates the fissure component, and the high curve with maximum discharge shows the existence of conduit voids. Aquifers hold groundwater in what is called the water table. This is one of the last stages of what is known as the water cycle, which is the natural cycle that water travels through on Earth. The ...Groundwater does flow through the High Plains Aquifer, but at an average rate of only 300 millimeters (12 inches) per day. The depth to the water table of the Ogallala Aquifer varies from actual surface discharge to over 150 meters (500 feet). Generally, the aquifer is found from 15 to 90 meters (50 to 300 feet) below the land surface. These rocks have different porosity and permeability characteristics, which means that water does not move around the same way in all rocks below ground. When a water-bearing rock readily transmits water to wells and springs, it is called an aquifer. Wells can be drilled into the aquifers and water can be pumped out.The Ogallala Aquifer (oh-guh-LAH-lah) is a shallow water table aquifer surrounded by sand, silt, clay, and gravel located beneath the Great Plains in the United States. As one of the world's largest aquifers, it underlies an area of approximately 174,000 sq mi (450,000 km 2) in portions of eight states (South Dakota, Nebraska, Wyoming, Colorado, Kansas, Oklahoma, New Mexico, and Texas). 14.1 Groundwater and Aquifers. Groundwater is stored in the open spaces within rocks and within unconsolidated sediments. Rocks and sediments near the surface are under less pressure than those at significant depth and therefore tend to have more open space.
