Our Work Water Conservation

Protecting the Colorado River, its tributaries, and groundwater in the Grand Canyon region.

Water is our most precious resource

The Southwest is already hot and dry, but add in climate change, and this arid region is getting even more parched. As the worst drought in a millennium drags on, we’re working to keep water in our rivers and water underground.

Surface water

The Colorado River and its tributaries have carved through the heart of the Southwest and deliver water to Colorado, Wyoming, Utah, New Mexico, Nevada, Arizona, California, many Native American tribes, and Mexico.

Groundwater

Groundwater starts as rain and snow, soaks into the ground, and is stored in aquifers — layers of porous rocks and soils. It is an important source of water for towns, and where it bubbles to the surface at springs, life flourishes.

Water conservation in the Southwest

From improving water policy at the national level, to surveying remote springs, we’re dedicated to protecting and conserving water in the Southwest. Here’s how we’re protecting precious waters in the Grand Canyon region.

We advocate for smart water policy

The Colorado River is overtapped. We need new rules to sustain the river’s flows.

We work with local communities

As populations grow, communities need new tools to protect their groundwater.

We restore springs and streams

In the desert, water is life. Plants and animals need clean, healthy waters too.

We protect water in the Grand Canyon

The Colorado River carved the Grand Canyon and is a lifeline for many creatures.

Colorado River water supply and demand

Water managers in the 1920s overestimated the amount of water in the Colorado River, so states were promised water the river could never provide. Now, states are grappling with water shortages that are worsening with prolonged drought.

There’s not enough water in the Colorado River

1 acre foot = enough water to cover 1 acre with 1 foot of water, or about 325,851 gallons

Conserving groundwater in Arizona

Arizona has lax rules on groundwater pumping and historically has used more water than rain and snowmelt can replenish. Since it’s hard to manage something you can’t see, communities need new tools and guidelines to conserve their water supplies.

Understanding and protecting rare water sources

The Southwest is dry — you can see it in the parched landscapes and feel it in your cracked skin. But look a little closer and you find rare pockets of water where willows grow, bobcats drink, and birds feed.

We work to understand how wildlife and plants use springs, and we find ways to restore these precious desert watering holes. From studying water quality and documenting flows, to pulling invasive tamarisk trees, to stopping unsafe uranium mining, we aim to balance the needs of plants, animals, people, and communities.

Spring surveys

We visit springs on foot to record water quality and document conditions. What we find helps prioritize restoration projects.

Spring restoration

Sometimes we build fences, other times we pull weeds. With hard work and time, degraded springs recover.

Wetland protection

Volunteers help us strengthen streambanks and build rock mosaics that slow water and prevent erosion of wetland areas.
