What Is The Ogallala Aquifer And Why Is It Running Out Of Water?
--
https://www.kansascity.com/news/politics-government/article281504238.html <-- shared media article
--
"Millions of years ago, sediment from the Rocky Mountains was deposited in the High Plains. Over thousands of years, water dripped below the surface creating an underground water deposit called the Ogallala Aquifer. The water — which spans from South Dakota to Texas and was once the size of Lake Huron — at one point accounted for 30% of the crop and animal production in the U.S…
Although the water source stretches across several states it moves very very slowly. As a result, no interstate compact exists to manage the water in the Ogallala. Instead, neighbors have to band together if they want to restrict pumping…”
