Yet in Kansas and Texas, pumps are draining it faster than rainfall can recharge it. Some wells have already lost more than 80 meters. How far can the Ogallala go down?<\/strong><\/p>\n<figure class=\"wp-block-image size-large\"><\/figure>\n<h2 class=\"wp-block-heading\">In the 1950s, the Great Plains uncover a hidden treasure beneath their fields<\/h2>\n<p>At first glance, nothing betrays its presence. Beneath wheat, corn and cotton lies, however, <strong>a gigantic underground reservoir<\/strong> made of sands, gravels and silts. The High Plains aquifer covers about 450,000 km\u00b2 across eight U.S. states, from South Dakota to Texas.<\/p>\n<section class=\"incontent-related\"><span class=\"incontent-related__title\">Read also<\/span> <span class=\"incontent-related__desc\">From the Danube to the Black Sea, nitrogen and phosphorus excesses end up suffocating seabed ecosystems<\/span><\/section>\n<p>After World War II, the arrival of powerful pumps upended regional farming. Water long out of reach suddenly made it possible to irrigate semi-arid lands on a large scale. The problem emerges a few decades later: <strong>this stock is not inexhaustible<\/strong>. Heavy withdrawals lower the water table far faster than it can replenish.<\/p>\n<h2 class=\"wp-block-heading\">The staggering figure: some sites have lost more than 80 meters of water<\/h2>\n<p>Measurements by the US Geological Survey tell this story with almost unsettling precision. Between the period before intensive irrigation, around 1950, and 2019, the average level of the aquifer fell by about <strong>five meters<\/strong>. An apparently reassuring average, because regional variations are substantial.<\/p>\n<p>In some Texas wells monitored by scientists, the decline reaches <strong>265 feet, or nearly 81 meters<\/strong>. On the scale of the entire aquifer, about 286 million acre-feet (roughly <strong>353 trillion liters<\/strong>) of recoverable water have disappeared since the start of intensive development, roughly 10% of the estimated stock.<\/p>\n<section class=\"incontent-related\"><span class=\"incontent-related__title\">Read also<\/span> <span class=\"incontent-related__desc\">Heating: what each solution really costs this winter<\/span><\/section>\n<p>The geographic contrast is striking. Some parts of Nebraska have seen relatively stable levels, or even slight increases, while <strong>Texas and western Kansas<\/strong> have experienced the most dramatic losses. It is not the Ogallala as a whole collapsing evenly, but rather its southern sectors subjected to heavy irrigation that are draining fastest.<\/p>\n<h2 class=\"wp-block-heading\">Why a few years of rain will never be enough to repair decades of pumping<\/h2>\n<p>A aquifer is not an underground lake that every thunderstorm would instantly refill. Water must pass through soil and rock layers before reaching the aquifer. In the driest areas, a large share of precipitation returns to the atmosphere. <strong>Natural recharge remains therefore very slow<\/strong>, especially in the south.<\/p>\n<p>In Kansas, the difference is telling. The Kansas Geological Survey estimates annual natural recharge for the Ogallala portion at about 0.75 million acre-feet (roughly <strong>930 billion liters of water<\/strong>), while withdrawals have historically run far higher. In some areas, <strong>more than 60% of the initial thickness<\/strong> of the aquifer has already vanished.<\/p>\n<section class=\"incontent-related\"><span class=\"incontent-related__title\">Read also<\/span> <span class=\"incontent-related__desc\">Bed bugs: what a treatment really costs, and who should pay<\/span><\/section>\n<h2 class=\"wp-block-heading\">When water becomes too deep, the Great Plains\u2019 agriculture must reinvent itself<\/h2>\n<p>Water loss does not necessarily mean a well suddenly runs dry. Its flow first declines, while <strong>the cost of pumping rises<\/strong>. Then a threshold arrives where fueling the gigantic circular irrigation systems visible from the sky simply isn\u2019t profitable anymore.<\/p>\n<p>In the Texas Panhandle, 2025 data published by the High Plains Underground Water Conservation District indicated an average saturated thickness of the Ogallala of about <strong>51 feet, or 15.5 meters<\/strong>, with a new average annual decline of 0.66 feet (20 centimeters). For some growers, each season brings the moment closer when irrigation will have to be abandoned.<\/p>\n<p>Yet Kansas shows that slowdowns remain possible. After decades of retreat, consolidated data indicate that the state\u2019s southwest has lost 1.36 feet (about 41 centimeters) in 2024, followed by <strong>0.62 feet (about 19 centimeters)<\/strong> in 2025. Voluntary reductions in withdrawals, less water-intensive crops, and new irrigation practices can therefore buy more time.<\/p>\n<section class=\"incontent-related\"><span class=\"incontent-related__title\">Read also<\/span> <span class=\"incontent-related__desc\">Asian hornet: the law has changed, garden traps haven\u2019t<\/span><\/section>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":3164,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[2275,2276,752,2279,2278,2274,2277,2280],"class_list":["post-3163","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news","tag-aquifer","tag-depleting","tag-faster","tag-kansas","tag-naturally","tag-ogallala","tag-recharges","tag-texas","generate-columns","tablet-grid-50","mobile-grid-100","grid-parent","grid-50"],"_links":{"self":[{"href":"https:\/\/www.farmersforum.ie\/trends\/wp-json\/wp\/v2\/posts\/3163","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.farmersforum.ie\/trends\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.farmersforum.ie\/trends\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.farmersforum.ie\/trends\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.farmersforum.ie\/trends\/wp-json\/wp\/v2\/comments?post=3163"}],"version-history":[{"count":1,"href":"https:\/\/www.farmersforum.ie\/trends\/wp-json\/wp\/v2\/posts\/3163\/revisions"}],"predecessor-version":[{"id":3165,"href":"https:\/\/www.farmersforum.ie\/trends\/wp-json\/wp\/v2\/posts\/3163\/revisions\/3165"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.farmersforum.ie\/trends\/wp-json\/wp\/v2\/media\/3164"}],"wp:attachment":[{"href":"https:\/\/www.farmersforum.ie\/trends\/wp-json\/wp\/v2\/media?parent=3163"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.farmersforum.ie\/trends\/wp-json\/wp\/v2\/categories?post=3163"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.farmersforum.ie\/trends\/wp-json\/wp\/v2\/tags?post=3163"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
