As drought continues to affect California, homeowners must balance two needs: preserving landscaping with irrigation while doing so as efficiently as possible to conserve water.
Even when not in a drought, trees planted in a Mediterranean climate often need additional water. For the most effective irrigation, mimic the way Mother Nature provides water.
Until the first half of the 20th century, some areas in Los Angeles County had very high groundwater and springs that residents could use as a water source, said Madelyn Glickfeld, co-director of the UCLA Water Resources Group.
Standing atop a pockmarked red mesa, Rod Colwell looks out at an expanse of water that resembles a thin blue strip on the horizon. The Salton Sea, California’s largest lake, has come and gone at least five times in the last 1,300 years, most recently in 1905, when floodwaters from the Colorado River refilled its basin.
A mid-century resort destination, the lake has since become an environmental disaster zone.
Increasing evaporative demand is escalating summertime drought severity in California and the West, according to climate researchers.
Evaporative demand is essentially the atmosphere’s “thirst.” It is calculated based on temperature, humidity, wind speed and solar radiation. It’s the sum of evaporation and transpiration from plants, and it’s driven by warmer global temperatures, which can be attributed to climate change.
Importing muddy water from the Mississippi River to save Arizona from drought could be as simple as landing a man on the moon.
As droughts force local communities to find alternative solutions to water shortages, Arizonans could turn to importing flood water in the future.
An unlikely energy sector is emerging as a winner from the West’s megadrought: fossil fuels, whose heavy use has been blamed for creating the conditions causing the drought in the first place.
The drought has slashed the electricity-generating capacity of major hydroelectric dams, forcing buyers to spend millions of dollars to buy extra power from an expensive sellers’ market.
Nestled below rocky outcroppings dotted with junipers on the eastern shore of old Tule Lake, John Prosser’s 97-acre homestead at Bloody Point is a haven amidst the chaos of the Klamath Basin water crisis.
Prosser, a history buff, purchased the property last fall, its fields having sat largely fallow for years despite the presence of a private irrigation well. By August, the field’s newly planted stand of alfalfa was busy rebounding after its first cutting — a rare sight of green in the Klamath Project this year.
The City of Oceanside received an Award of Excellence during the WateReuse conference in September 2021. Oceanside received the Recycled Water Outreach/Education Program Award for Pure Water Oceanside, which pays tribute to an agency that demonstrates a significant and wide-reaching community outreach and/or public education program that informs the community about the presence and benefits of water reuse.
Global scientists reported in August that due to the climate crisis, droughts that may have occurred only once every decade or so now happen 70% more frequently. The increase is particularly apparent in the Western US, which is currently in the the throes of a historic, multiyear drought that has exacerbated wildfire behavior, drained reservoirs and triggered water shortages.
More than 94% of the West is in drought this week — a proportion that has hovered at or above 90% since June — with six states entirely in drought conditions, according to the US Drought Monitor. On the Colorado River, Lake Mead and Lake Powell — two of the country’s largest reservoirs — are draining at alarming rates, threatening the West’s water supply and hydropower generation in coming years.
In July, Gov. Gavin Newsom called on Californians to voluntarily reduce their water use by 15 percent “through simple actions such as reducing landscape irrigation, running dishwashers and washing machines only when full, finding and fixing leaks, installing water-efficient showerheads and taking shorter showers.”
Turns out those suggestions weren’t enough, especially in San Diego.
