Tobyn Pilot took a few crunchy footsteps through the rough red dirt near the edge of a towering cliff. Pilot, an operator at the water plant in Page, Arizona, pulled out a hefty collection of keys and unlocked a tiny plywood-paneled shed just a few feet from the brink. The building is barely bigger than an outhouse, but it’s a pivotal part of keeping the taps flowing.
Thousands of years ago during the last Ice Age, rivers flowed from giant glaciers in the Sierra Nevada down to the Central Valley, carving into rock and gouging channels at a time when the sea level was about 400 feet lower. When the glaciers retreated, meltwater coursed down and buried the river channels in sediment.
A U.S. agency seeking to restore habitat for endangered fish gave final approval on Thursday to decommission four dams straddling the California-Oregon border, the largest dam removal undertaking in U.S. history. Dam removal is expected to improve the health of the Klamath River, the route that Chinook salmon and endangered coho salmon take from the Pacific Ocean to their upstream spawning grounds, and from where the young fish return to the sea.
When you think about renewables, it’s natural that solar power and wind may come to mind. But have you ever thought about how to generate energy when the sun is down and the winds are calm? Neena Kuzmich, with the San Diego County Water Authority, explains with big climate goals on the horizon, cities like San Diego are tapping into the world of pumped storage hydropower.
Recognizing that a reliable water supply is critical to all economies and communities relying on the drought-stricken Colorado River Basin, more than 30 water agencies and providers have committed to take additional actions to reducing water demands and helping protect the Colorado River system.
US regulators approved a major milestone Thursday in a plan to demolish four dams on a California river and open up hundreds of miles of salmon habitat that would be the largest dam removal and river restoration project in the world when it goes forward. The Federal Energy Regulatory Commission vote on the lower Klamath River dams is the last major regulatory hurdle and the biggest milestone for a $500 million demolition proposal championed by Native American tribes and environmentalists for years.
Staff and board members from the Glenwood Springs-based Colorado River Water Conservation District, along with other water managers from across western Colorado, this month visited the lower basin states — Nevada, Arizona and California — on what they called a fact-finding trip. The tour took participants by bus from Las Vegas though the green alfalfa fields of the Fort Mohave Indian Reservation, past the big diversions serving the Central Arizona Project and Metropolitan Water District of Southern California, and to the hot, below-sea-level agricultural expanse of the biggest water user on the river: the Imperial Irrigation District.
This third year of extreme drought is taking a devastating toll on agriculture in California. We see pictures of orchards being removed, dry canals and fields that should be a verdant green now a sunburned brown. The impacts on the farm are easy to see. The effects on our communities and on the wildlife that depend on agricultural lands in production are no less real, even if they are harder to observe.
For at least a decade, off and on, state water managers and local water agencies have pursued the holy grail of a master agreement to improve the environmental health of the Sacramento-San Joaquin Delta by increasing its water flows.
California is enjoying fewer extreme wildfires than it has in years, which experts attribute to a combination of summer rain, calm weather and increased forest management.
