Ogallala aquifer definition
Reduced surface-water flows In most areas, the surface- and ground-water systems are intimately linked. Ground-water pumping can alter how water moves between an aquifer and a stream, lake, or wetland by either intercepting ground-water flow that discharges into the surface-water body under natural conditions, or by increasing the rate of water movement from the surface-water body into an aquifer.The aquifer underlies eight states of the nation’s breadbasket — including Nebraska, Kansas, and Texas — and spans 175,000 square miles. Dependence on the Ogallala has depleted its supply by 30% to date, as shown in Figure 1. 90% of water withdrawn from the Ogallala is used for agricultural irrigation.Jul 27, 2020 · See Water Resources Research Act of 1984, 42 U.S.C. § 10301 note (2018) (Ogallala Aquifer Research and Development) (“The Secretary, acting through the United States Geological Survey and in cooperation with the States of the High Plains region, is authorized and directed to monitor the levels of the Ogallala aquifer, and report biennially ...

Ogallala Aquifer. The Ogallala Aquifer occupies the High Plains of the United States, extending northward from western Texas to South Dakota. The Ogallala is the leading geologic formation in what is known as the High Plains Aquifer System. The entire system underlies about 450,000 square kilometers (174,000 square miles) of eight states.Figure 1. Figure depicting the saturated thickness of a simple unconfined aquifer. Modified from StudyBlue, 2020. Because the saturated thickness of an aquifer is directly related to the groundwater volume available for extraction, quantifying the saturated thickness at the beginning of the growing season is critical to irrigation planning and perhaps even to crop selection.The aquifer is found from 30 to 100 meters deep over about 440,000 square kilometers! The water in the aquifer is mostly from the last ice age. People widely use the Ogallala Aquifer for municipal and agricultural needs. About eight times more water is taken from the Ogallala Aquifer each year than is replenished.

Sole Source Aquifer. A Sole Source Aquifer (SSA) is an aquifer that has been designated by the United States Environmental Protection Agency (EPA) as the sole or principal source of drinking water for an area. [1] By definition, SSA is an aquifer that supplies at least 50% of the drinking water consumed in the area overlying the aquifer. Based on this definition, the Ogallala Aquifer’s rapid depletion is considered a wicked problem due to the vast number of stakeholders involved, resulting in numerous opinions and therefore conflicts regarding how to resolve the issues surrounding the Ogallala depletion.Mar 4, 2022 · The Ogallala Aquifer is located beneath the Great Plains or High Plains regions in the United States of America. It covers eight states and makes up an important water resource for about 27% of the land that is under irrigation in the country.

The Ogallala Aquifer is a vital source of water since it supplies 81% of the water used in the High Plains area. The remaining 19% of water comes from surface water (U.S. Geological Survey, 2008). Most of this groundwater is used in irrigation since 54% of the land within the Ogallala Aquifer region is used for agriculture. The Ogallala or High Plains Aquifer sits under 450,000 km 2 of 8 states of the United States of America. It is one of the largest freshwater deposits in the world. The aquifer is composed of unconsolidated alluvial deposits. Groundwater in this aquifer has been dated to have been deposited in the humid time following the last glacial maximum.Covering an area of 174,000 square miles, the Ogallala Aquifer is one of the largest aquifers of the United States of America (APEC Human Resource Development ...

Fossil water, also known as paleowater is an underground water reservoir that is geologically located in an undisturbed place. That is, the water cannot be replenished and may have been locked in the aquifer for thousands of years. The age of the water is what gives it the name “fossil water.”. monocular depth cues examples Playa wetlands form in small, shallow topographic depressions on the landscape of the western Great Plains.
