Water security research

The American West, national groundwater reliance, and realistic options to secure U.S. water supplies. Read the source-backed briefs alongside the existing scenario datasets and their assumptions.

The American West, basin by basin

A broad planning region requires local water budgets. Follow water from mountain precipitation to farms, communities, streams, and underground storage.

brief

Groundwater is more than an aquifer map

Aquifers are geological formations that store and transmit groundwater. Groundwater analysis evaluates the water itself: its availability, movement, quality, and response to withdrawals.

brief

Build dependable water security from a measured portfolio

Start by repairing avoidable losses and reducing verified consumption. Compare reuse, recharge, and existing storage improvements next; add supply where a measured drought-year gap remains. The strongest portfolio depends on local water, infrastructure, rights, and affordability.
