Water Resources & Management

As all New Mexicans know, water in our state is a very precious - and at times elusive - resource. Even with New Mexico's wonderful diversity of ecosystems , the mostly desert landscape receives an average of 10 inches of precipitation annually...

Surface water (rivers, lakes and streams) in New Mexico originates as rain or melting snow, but over 95% of that water evaporates or is transpired by plants.

Most of New Mexico’s fresh water is stored as groundwater in aquifers or confining layers below the land surface, where it occupies small open spaces between sand or gravel and small fractures in rock.

NMED has many programs that focus on protecting the quality of our waters and assuring safe and effective infrastructure for delivering clean water to our communities. We coordinate much of our work with federal agencies, other state agencies, local governments, and citizen groups.
