Tribe Signs Pact With California to Work Together on Efforts to Save Endangered Salmon

A California tribe has signed agreements with state and federal agencies to work together on efforts to return endangered Chinook salmon to their traditional spawning areas upstream of Shasta Dam, a deal that could advance the long-standing goal of tribal leaders to reintroduce fish that were transplanted from California to New Zealand more than a century ago and still thrive there.

Reborn From Record Winter, Tulare Lake Could See Explosive Growth From Snowmelt

Tulare Lake has sprung back to life, its shoreline rapidly expanding from the runoff of a winter of epic rainstorms and the melting of the massive southern Sierra snowpack.

Is It a Lake, or a Battery? A New Kind of Hydropower Is Spreading Fast.

For a century, hydroelectric power has been synonymous with gigantic dams — feats of engineering that provide renewable energy but displace communities and destroy ecosystems.

New research released Tuesday by Global Energy Monitor reveals a transformation underway in hydroelectric projects — using the same gravitational qualities of water, but typically without building large, traditional dams like the Hoover in the American West or Three Gorges in China. Instead, a technology called pumped storage is rapidly expanding.

No Mow May? Good Intentions, Bad Approach, Critics Say

If you’re reading this, chances are you’ve heard about the #NoMowMay movement that’s been gaining steam on social media and in eco-conscious circles these past few years.

Started in 2019 by citizen scientists in the United Kingdom, the call for homeowners to abstain from mowing their lawns during the month has spread to other countries, including the U.S.

The intention is admirable: Let your grass and weeds grow and bloom to provide food and shelter for essential pollinators like bees and butterflies early in the season, when such necessities may be scarce.

Trolls Under the Bridge: Century Old Dam Faces Bleak Future

Every day, more than 300,000 cars and trucks thunder across the wide concrete bridge which carries Interstate 15 over Lake Hodges south of Escondido. Perhaps just a handful of these daily commuters or big rig drivers are fully aware of what lies below. Under this bridge, an aluminum boat and fisherman could be bobbing among the treetops. On another day, it might be the peaceful scene of a mule deer lying perfectly still on dry ground among the reeds.

As Water Crisis Persists, San Diego Looks at Treated Wastewater as a Drinking Water Source

As Arizona faces an ongoing mega-drought and a mounting water crisis, leaders are looking for ways to ensure Arizona’s water supply.

In 2023, Arizona will lose 20% of its water allotment from the Colorado River, and countless steps are have been taken by government officials in the state, with water conservation plans implemented by various cities.

IID Testifies on Colorado River Status and Impacts to State Assembly

Representatives of the Imperial Irrigation District (IID) and the Colorado Board of California testified on Tuesday at an informational hearing about how Southern California is preparing for climate impacts to water supplies and the river’s status.

IID Board Vice President and California’s Colorado River Commissioner JB Hamby and IID Water Department Manager Tina Shields testified before the California State Assembly’s Water, Parks, and Wildlife standing committee.

Opinion: When Flooding Season Runs Into Fire Season

The state’s first notable wildfire of the year broke out a week ago in the San Bernardino National Forest, signaling the start of the fire season and creating an odd juxtaposition.

At about the same time, some 300 miles to the north, Yosemite National Park announced it was temporarily closing because of the threat from anticipated melting of the vast Sierra snowpack.

California, which has been battered by extreme weather for some time, is used to being whipsawed by the elements — though not quite like this past year.
