Momentum is building for a unique interstate deal that aims to transform wastewater from Southern California homes and business into relief for the stressed Colorado River. The collaborative effort to add resiliency to a river suffering from overuse, drought and climate change is being shaped across state lines by some of the West’s largest water agencies.
Some water use restrictions that were imposed on most Marin County residents during the drought last year are now set to become permanent.
The Marin Municipal Water District Board of Directors voted unanimously on Tuesday to continue limiting sprinkler use to two days per week, which is down from three days it allowed before it adopted its drought restrictions in 2021. Drip irrigation will be allowed three days a week. All pool owners in the district must also have a pool cover.
The U.S. Bureau of Reclamation announced two measures today to boost water levels in Lake Powell, keeping them high enough to continue generating hydropower at the Glen Canyon Dam. Both moves are being framed as painful but necessary band-aids, cutting into reserves elsewhere in the region to stave off the worst effects of a decades-long drought that has sapped the nation’s second-largest reservoir.
One measure will send water from upstream to help refill Lake Powell. About 500,000 acre-feet of water will be released from Flaming Gorge Reservoir, which straddles the border between Wyoming and Utah.
Despite years of drought and conservation mandates, Californians continue to sprinkle a lot of clean, drinkable water onto yards to keep the greenery alive. That’s true even on properties that have scaled back thirsty lawns and added drought-tolerant native plants.
Now, however, Southern California officials have imposed unusually strict limits on outdoor water use in response to a water shortage emergency, effective June 1. So you may need to find an alternative way to keep your plants from desiccating in the summer sun.
Heat waves. Severe drought. Extreme wildfires.
As Southern California braces for unprecedented drought restrictions, long-range forecasts are predicting a summer that will be fraught with record-breaking temperatures, sere landscapes and above-average potential for significant wildfires, particularly in the northern part of the state.
“The dice are loaded for a lot of big fires across the West,” said Park Williams, a climate scientist at UCLA. “And the reason for that is simple: The vast majority of the western U.S. is in pretty serious drought.”
With little hope of reprieve ahead of the warming summer months, demand for water in parts of drought-stricken California is outpacing supply.
The metropolitan water district of southern California declared a water shortage emergency last week for areas that rely on the State Water Project, a sprawling system of canals, reservoirs, and pipelines that snake across roughly two-thirds the length of the state, affecting about 6 million southern Californians in Los Angeles, San Bernardino and Ventura counties.
It was a perfectly decent patch of lawn, several hundred square feet of grass in a condominium community on this city’s western edge. But Jaime Gonzalez, a worker with a local landscaping firm, had a job to do.
Wrangling a heavy gas-powered sod cutter, Mr. Gonzalez sliced the turf away from the soil underneath, like peeling a potato. Two co-workers followed, gathering the strips for disposal.
In an effort to boost water supply reliability for millions of Californians, the California Department of Water Resources (DWR) has announced its first round of funding to 20 agencies responsible for managing critically overdrafted groundwater basins throughout the state.
A total of $150 million in funding is being awarded to regional groundwater agencies through the Sustainable Groundwater Management (SGM) Grant Program. The funding will go toward projects focused on water efficiency, groundwater recharge, feasibility studies for alternative water supplies, and the installation of monitoring wells.
About 40 miles north of the California-Mexico border lies the shrinking, landlocked lake known as the Salton Sea. Once the epicenter of a thriving resort community, water contamination and decades of drought have contributed to a collapse of the lake’s once vibrant ecosystem, and given rise to ghost towns.
But amidst this environmental disaster, the California Energy Commission estimates that there’s enough lithium here to meet all of the United States’ projected future demand, and 40% of the entire world’s demand.
Ongoing dry weather in the western U.S. conducive to wildfires burning in New Mexico and Arizona has also helped drop the waters of Lake Powell to a level approaching the minimum needed to operate the Glen Canyon Dam hydroelectric power plant.
“This year the Colorado River Basin has experienced extremely variable conditions with a record high snowpack one month, followed by weeks without snow,” David Palumbo, acting commissioner of the U.S. Bureau of Reclamation, said in a statement. “This variable hydrology and a warmer, drier west have drastically impacted our operations and we are faced with the urgent need to manage in the moment.”
