Key issues in New Mexico
Drought
Much of the American West is in a multi-decade dry period that researchers describe as the most severe in over a millennium, reshaping how communities plan for water.
ExploreColorado River
The river that supplies 40 million people has lost roughly a fifth of its flow since 2000, forcing a renegotiation of how seven states share the water.
ExploreGroundwater Depletion
Aquifers from the Central Valley to the Ogallala are being pumped faster than they recharge, causing land subsidence and threatening long-term supply.
ExplorePotable Reuse
Advanced purification turns treated wastewater into water that meets or exceeds drinking-water standards — increasingly essential in water-stressed regions.
ExploreAgricultural Demand
Agriculture accounts for the majority of consumptive water use in the West, making farm efficiency and water markets central to any supply solution.
ExploreProduced Water
Oil and gas wells generate billions of barrels of salty, contaminated water. Arid states are debating whether to treat and reuse it — and how safely.
ExploreTribal Water Rights
Native nations hold some of the oldest and largest water rights in the West — often unquantified for a century. Settlements are now reshaping basin allocations.
ExploreWater Rights
In the West, water is governed by 'first in time, first in right' — a century-old legal system now colliding with scarcity, cities, and the environment.
