Depending on geologic and hydrologic conditions of the aquifer, the impact on the level of the water table can be short-lived or last for decades, and it can fall a small amount or many hundreds of feet. In 2012, the parts of the Kansas region created local enhanced management areas, enforced by law, in which the goal is to reduce water use by 20% over a five-year period (Wise, 2015). Mais) Whe.

In an era of growing population and advancing drought, we cannot afford complacency in the face of “creeping normalcy.”. The Ogallala Aquifer is a huge table of groundwater that covers portions of eight Western States. Streams and rivers that depend on the aquifer are drying out after decades of over-pumping. This extensive formation of "fossil water" is being rapidly depleted by heavy withdrawals by farmers and at one time was expected to last no more than 40 years. In the High Plains Aquifer, of which the Ogallala is part, “there’s not a freshwater resource deeper” for farmers to drill down into, says Dennehy. Although water levels have actually risen in some areas, especially Nebraska, water levels are mostly in decline, namely from Kansas southward. As one scientist put it: there are too many straws in the resource. The Ogallala Aquifer is named for resting atop of the Ogallala Formation of the Miocene Age, which is considered the principal geological unit of the aquifer. And the Ogallala's sand and gravel composition slowed the downward flow of surface waters to refill it, even in wet seasons. This is a long term event that will increase demand on the aquifer while reducing the ability of the aquifer to recharge. Using a comprehensive set of conservation practices, the Ogallala Aquifer Initiative (OAI) aims to reduce aquifer water use, improve water quality and enhance the economic viability of croplands and rangelands in Colorado, Kansas, Oklahoma, Nebraska, New Mexico, Texas, South Dakota and Wyoming.

Careful management of the Ogallala aquifer resource today and for the long- term is critical to communities of this region. Underground, the region’s lifeblood – water – is disappearing, placing one of the world’s major food-producing regions at risk. Required fields are marked *. The aquifer extends, roughly, from Midland, Texas, through the Texas Panhandle and all the way to South Dakota. Your email address will not be published. The Ogallala, also known as the High Plains Aquifer, is one of the largest underground freshwater sources in the world. Likewise, people ask, what is the biggest threat to the Ogallala Aquifer? The depth of the aquifer from the surface of the land, its reate of natural thickness, vary from region to region. aquifer from the surface of the land, and its natural thickness, vary from region to region.6 As a whole the aquifer covers 174,000 square miles and has long been a major source of water for agricultural, municipal, and industrial development. Most people have never heard of the Ogallala (also known as the High Plains Aquifer) to some degree because it is rarely visible as surface water.. If it runs dry, it will take about 6,000 years to fill back up. Aside from the devastating effects on agriculture, a study recently published by a team of stream ecologists concluded that depletions to the Ogallala Aquifer are also leading to fish extinctions in the region.
