The number governing western Kansas water policy is 2070, when the Ogallala Aquifer is projected to hit 70 percent depletion. That projection, from the USDA's 2024 synthesis, assumes a continuation of historical drawdown trends measured during decades of warming at roughly 0.2°C per decade. The documented rate is now 0.35.
Peer-reviewed modeling of the northern High Plains shows that under accelerated warming, irrigation demand climbs 15 to 25 percent while recharge drops catastrophically. A Journal of the American Water Resources Association study projects depletion rates increasing 50 percent under hotter, drier conditions. Even a conservative read compresses that 2070 deadline to roughly 2055. Governor Kelly's new water task force, the Southwest Kansas Groundwater Management District's 25-year preservation plans, the proposed consolidation of 14 groundwater districts into one office: all of it is being assembled around a timeline the atmosphere has already shortened.
