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.
The San Diego County Water Authority has approved a new contract with the Mission Resource Conservation District to administer the SDCWA’s WaterSmart Field Services Program. The Thursday, Oct. 27, CWA board action authorized CWA general manager Sandra Kerl to enter into a three-year professional services agreement with the Mission RCD which will pay $200,000 for administration of the WaterSmart Field Services Program through Oct. 31, 2025.
Sweetwater Authority is again removing water from its Loveland Reservoir to meet customer needs during drought conditions, but the move will halt the lake’s free fishing program.
The agency, which serves roughly 200,000 South County customers, began moving water downstream to its Sweetwater Reservoir this week. Officials said its water supply took a hit because of the region’s lack of rainfall and that transferring the water is a cheaper option than importing.
The San Diego County Water Authority has modified its Permanent Special Agricultural Water Rate calculation methodology. The Thursday, Oct. 27, SDCWA board meeting included approval of the modification which allows participating agencies the ability to prescribe how their local supply is allocated under the PSAWR program.
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.
With the federal government calling for major cuts in water use to address the historic shortage on the Colorado River, the leaders of 30 agencies that supply cities from the Rocky Mountains to Southern California have signed an agreement committing to boost conservation, in part by pledging to target the removal of one especially thirsty mainstay of suburban landscapes: decorative grass.
