A proposal to build a project to capture water in California’s Sacramento-San Joaquin Delta during wet weather and make it available in drier areas is advancing as state officials anticipate losing 10% of its water supply by 2040 as a result of hotter temperatures.
California water regulators have released a long-awaited analysis of options for managing flows in the Sacramento-San Joaquin River Delta, where fish populations have been declining and the ecosystem has been deteriorating.
The delta is the central hub of the state’s water system, drawing together rivers from a vast watershed and supplying pumps that send water flowing to cities and farms.
The Biden administration’s environmental justice office is investigating whether California’s water agency has discriminated against Native Americans and other people of color by failing to protect the water quality of San Francisco Bay and the Sacramento-San Joaquin Delta.
The U.S. Environmental Protection Agency’s investigation was triggered by a complaint filed by tribes and environmental justice organizations that says the the state Water Resources Control Board for over a decade “has failed to uphold its statutory duty” to review and update water quality standards in the Bay-Delta.
It’s gone by several names: Peripheral Canal, Water Fix and Delta Conveyance.
Its design has changed several times, from a canal to twin tunnels and most recently a single tunnel.
However, its purpose has been unchanged for seven decades – bypassing the Sacramento-San Joaquin Delta as water is moved from Northern California to San Joaquin Valley farms and Southern California homes.
When California imposed its first-ever regulation on the extraction of water from underground aquifers in 2014, it gave environmental groups a landmark victory in their decades-long effort to overhaul water use laws.
It was also a political setback for farmers, who are California’s major water users and have depended on wells to irrigate their crops as increasingly frequent droughts reduce surface water in rivers and reservoirs.
Two winters’ worth of snow has already fallen in the Sierra Nevada since Christmas, pulling California from the depths of extreme drought into one of its wettest winters in memory.
But as a series of tropical storms slams the state, that bounty has become a flood risk as warm rains fall on the state’s record snowpack, causing rapid melting and jeopardizing Central Valley towns still soggy from January’s deluges.
Agriculture in the San Joaquin Valley may be able to blunt a sharp decline in the years ahead if policymakers and the industry can come together on a series of strategies for reducing demand for irrigation while also increasing water supply, according to a new assessment from a prominent policy organization.
The report this month from the Public Policy Institute of California examined the biggest challenge confronting the state’s ag industry then recommended softening the impact by loosening water-trading rules, incentivizing farmland reuse and investing in storage, including groundwater recharge.
You would have to be at least a septuagenarian to remember “Rebel Without a Cause,” a 1955 movie that starred James Dean and depicted the lives of aimless teenagers.
The film’s most memorable scene was a game of chicken in which two boys raced cars side by side toward a cliff and the first one to bail out was the loser. The “winner,” however, died when his car hurtled over the cliff.
The most important piece of California’s water puzzle is the Sacramento-San Joaquin Delta, the 1,100-square-mile estuary where the state’s two most important rivers meet. The Sacramento and San Joaquin rivers drain a watershed of mountains and hills that stretches about 400 miles from Mount Shasta, near the Oregon border, to the Sierra southeast of Fresno.
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.
