Earth Notes: Arizona’s Water Sentinels

Sentinels sampling water

People have been pitching in to help out some of Arizona’s endangered rivers—and they’re starting to make waves.

The Water Sentinels program got its start in 2006 as part of the Sierra Club’s Grand Canyon Chapter.

Members say they grew tired of seeing local streams degraded by pollution, or “reduced to bone-dry washes” because of dams, diversions, and pumping.

Now more than 100 regular volunteers work on two main rivers—the Verde and the Salt.

The Humpback Chub is Making a Comeback

Randall Babb Arizona Game and Fish Department

There was a time when scientists feared the demise of an ugly little fish called humpback chub, which has lived in southwestern rivers for millions of years. One of its last holdouts is in the Grand Canyon section of the Colorado River at a major tributary, the Little Colorado. Glen Canyon Dam took its toll on the little fish, and by the late 1990s, its population plummeted to a few thousand.

But these days, the humpback chub appears to be making a comeback.

The Grand Canyon Needs New Pipes

The aging pipeline that carries water from the inner Grand Canyon to the rims has been damaged five times so far this year, leading to breaks. This break occurred in May.

Grand Canyon National Park has issued five warnings this year about water shortages due to pipeline breaks. That means so far, it’s actually been a good year for the aging water system that park officials are dying to replace. 

Imagine hiking in the Grand Canyon and seeing a geyser. There are no natural geysers at Grand Canyon. But up to 25 times a year, the pipes break that carry water from the Inner Canyon to the rims.

New Life for Leroux Springs

Anne Minard KNAU

The San Francisco Peaks appear to be as parched as the surrounding high desert landscape.

It may surprise some people that there are springs hidden in the forests throughout the small mountain range.

And in theory, there’s plenty of water for the animals that make a home in the Peaks, and perhaps even for the people who visit.

The biggest of these, Leroux Spring, has appeared bone dry for almost a century because its water has been diverted for other uses.

To Carry It Out or Leave it. That's the Stinky Question Facing the Grand Canyon Managers.

Grand Canyon National Park is in the lengthy process of revamping its back country management plan, which  regulates where people can go and what rules they have to follow. 

The park’s plan is still a ways off, but one proposal that’s likely to surface could cause quite a stink.

Zack Summit, from Prescott, and a couple of his friends went backpacking in the Grand Canyon in early April.

Overall they had a pleasant time.

But Summit isn’t likely to forget his one early morning surprise.
