Returning the Colorado River to the Sea

This post is part of a series on the Colorado River Delta.

colorado-delta-100Once teeming with life and spanning some two million acres, the delta of the Colorado River ranked among the planet’s greatest desert deltas.

But more than half a century of damming and diverting the river’s flow to supply the burgeoning farms and cities of the American Southwest has dried out the delta’s wetlands and depleted the river.  In most years, the mighty Colorado – which sculpted the Grand Canyon – no longer reaches the sea.

But thanks to years of hard work by conservation groups on both sides of the U.S.-Mexico border, and a groundbreaking binational agreement to return a small volume of flow to the river and its delta, this aquatic wonder is poised for a revival.  As the water returns, so will the wetlands, birds, fish, and trees that once created a verdant and vibrant landscape.
