"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…

Instead, neighbors have to band together if they want to restrict pumping…” #GIS#spatial#mapping#hydrogeology#waterresources#watermanagement#modeling#ogallala#OgallalaAquifer#water#hydrology#watersecurity#pumping#mining#irrigation#farming#agriculture#midwest#aquifer#overpumping
