Despite our very moist winter, California’s water shortage woes aren’t completed.
Gov. Gavin Newsom has resisted declaring the drought to be over. Just this week, a proposal from President Biden raised the potential for new, painful water cuts for California. And the state appears more and more trapped in a sample of extreme storms adopted by excessive drought, with out a lot of a contented medium.
So maybe it goes with out saying that water conservation will proceed to be a central situation within the Golden State for years to come back.
A brand new state-funded undertaking within the San Joaquin Valley hopes to discover a new solution to construct drought resilience. The thought is easy: Cover the state’s canals and aqueducts with photo voltaic panels to each restrict evaporation and generate renewable power.
“If you drive up and down the state, you see a lot of open canals. And after year after year of drought it seemed an obvious question: How much are we losing to evaporation?” stated Jordan Harris, co-founder and chief govt of Solar AquaGrid, an organization primarily based within the Bay Area that’s designing and overseeing the initiative. “It’s just common sense in our eyes.”
The California Department of Water Resources is offering $20 million to check the idea in Stanislaus County and to assist decide the place else alongside the state’s 4,000 miles of canals — one of many largest water conveyance techniques on this planet — it could take advantage of sense to put in photo voltaic panels. The undertaking is a collaboration between the state, Solar AquaGrid, the Turlock Irrigation District and researchers with the University of California, Merced, who will observe and analyze the findings.
“This hasn’t been tried in the U.S. before,” stated Roger Bales, an engineering professor at U.C. Merced who makes a speciality of water and local weather analysis. “We want these to eventually be scaled across the western U.S., where we have a lot of irrigated agriculture and open canals.”
California’s efforts obtained a soar begin from a 2021 research revealed by Bales and his colleagues, who decided that overlaying the state’s canals with photo voltaic panels may cut back evaporation by as a lot as 90 % and save 63 billion gallons of water per 12 months — sufficient to satisfy the residential water wants of greater than two million individuals.
The workforce recognized different doable upsides: The installations may generate massive quantities of power; cut back algae progress and the necessity for upkeep by limiting daylight falling on the water; improve the functioning of the photo voltaic panels by permitting them to remain cool close to the water; and enhance air high quality by creating an power supply that may restrict the necessity for diesel-powered irrigation pumps.
The sheer variety of advantages documented within the research eased hesitations concerning the thought and “kind of changed our thinking,” stated Josh Weimer, spokesman for the Turlock Irrigation District, which volunteered its 250 miles of canals in Stanislaus County for the pilot. Another profit for the district, which can also be an influence supplier, is that it doesn’t want to purchase new, expensive tracts of land to put in photo voltaic panels because the canals are already its property.
The undertaking, anticipated to interrupt floor this fall, will begin out on simply two miles of canals within the Central Valley district. I lately visited certainly one of them within the small agricultural city of Ceres, simply outdoors Modesto off Highway 99, the place the concrete-banked canal winds via shady orchards and previous slender farm roads frequented by tractors.
The outcomes will very possible be intently watched. Harris instructed me he had already been contacted by water districts and canal operators around the globe — together with in Spain, the Philippines and Brazil — which can be inquisitive about replicating the design.
“This is a global issue, and potentially a big contributor to a global solution to evaporative losses and renewable energy generation at the same,” Harris stated.
Where we’re touring
Today’s tip comes from Nancy Hull, who lives in Colusa. Nancy recommends the North Table Mountain Ecological Reserve in Oroville for “wildflowers, lots of poppies and other small yellow and white flowers.” She writes, “It’s still blooming and I think more purple may be coming.”

Safari West, a wildlife protect in Santa Rosa, is celebrating the start of its first southern white rhino. Officials say the infant boy is wholesome and weighs between 80 and 100 kilos, ABC7 stories.
“Such a joy to watch!” Safari West tweeted.
