Nebraska’s Martha Shulski tells Brownfield there should be increased precipitation over the next decade for the the Ogallala Aquifer. “In terms of precipitation change, I see a decent amount of recharge taken place.  That’s in the shorter term. It could be a different story longer term if rates of extraction of water exceed what is replenished.”
