The San Joaquin River, which helps drain California’s Central Valley, has been negatively impacted by construction of dams, inadequate streamflows and poor water quality. Efforts are now underway to restore the river and continue providing agricultural lands with vital irrigation, among other water demands.
After an 18-year lawsuit to restore water flows to a 60-mile dry stretch of river and to boost the dwindling salmon populations, the San Joaquin River Restoration Settlement is underway. Water releases are now used to restore the San Joaquin River and to provide habitat for naturally-reproducing populations of self-sustaining Chinook salmon and other fish in the San Joaquin River. Long-term efforts also include measures to reduce or avoid adverse water supply impacts from the restoration flows.
If California is going to prevent further depletion of aquifers and survive droughts like the one that afflicted it from 2011 to 2017, the state will need to manage its groundwater usage. In the central valley, a group of organizations is working on a project that could stem the tide by combining two technologies: the internet of things (IoT) and Blockchain.
Four new voting members, each appointed by representatives of the Delta region, would be added to the Delta Stewardship Council if a bill authored by Assemblyman Jim Frazier becomes law. … Frazier introduced Assembly Bill 1194 this week. It would increase the voting membership of the council to 11 members.
It’s a treasure that is all too easy for Palo Alto to take for granted — an abundant supply of pristine water that flows from the Sierra Nevada snowpacks and passes through the Hetch Hetchy system before splashing out of local showers and faucets. Palo Alto is one of 25 cities that belong to the Bay Area Water Supply and Conservation Agency (BAWSCA), which manages the member cities’ supply agreement with the San Francisco Public Utilities Commission. … Even so, the cities don’t always know which projects they’re helping to fund.
Funding awarded for the new Temperance Flat Dam may have fallen short, but hopes for construction are still very much alive. Jason Phillips, Director of Friant Water Authority and alumni of the San Joaquin Valley Water Infrastructure Authority, has insight as to why those involved with the project are still optimistic.
To help build leadership capacity and acquire water management tools for valley communities, Self-Help Enterprises invites water board members and staff, water leaders, and residents from rural communities to participate in the 2019 Rural Communities Water Managers Leadership Institute. The six-month program is scheduled for March through August, with sessions held one Saturday per month at Self-Help Enterprises in Visalia.
State Senator Melissa Hurtado (D-Sanger) said Senate Bill 559, will “help secure California’s water supply by investing $400 million toward restoring lost (delivery) capacity on the Friant-Kern Canal, one of the San Joaquin Valley’s most critical water delivery facilities.” … The $400 million would be appropriated from the state general fund to the Department of Water Resources to administer the repairs.
Local groundwater regulatory agencies set up under 2014 legislation in California are discussing future rationing schemes with irrigators as they scramble to submit long-term aquifer sustainability plans to the state by a deadline of early next year. Local regulators are discussing a combination of new supplies and land-use conversions, says David Orth, a principal at the Fresno-based New Current Water and Land, LLC, a strategic planning firm.
The San Joaquin Valley—California’s largest agricultural region and an important contributor to the nation’s food supply—is in a time of great change. The valley produces more than half of the state’s agricultural output. Irrigated farming is the region’s main economic driver and predominant water user. Stress on the valley’s water system is growing. Local water supplies are limited, particularly in the southern half of the region.
The most eco-friendly wastewater treatment plant in the Northern San Joaquin Valley will be Manteca’s by the time 2020 rolls around. Not only is the treated water returned to the San Joaquin River meeting the latest standards established by the state for water quality, but within six months or so methane gas — a major byproduct of the treatment process that typically has to be burned — will no longer contribute to valley air quality issues.
Now stripped of its once vast wetlands and nearly sucked dry from the overpumping of groundwater during the West’s increasingly common droughts, the fertile valley is in need of a reboot: Its aquifers have shrunk and the remaining water is often contaminated with nitrate and salts. Citing a new water law that will have major effects on water suppliers and farmers, experts are calling for an “all hands on deck” approach to fixing the valley’s water woes.
This year, the water agency plans to inform farmers and the community about not only the amount of water the Tuolumne River Watershed has received so far this year, but also will provide information regarding the final license application for Don Pedro, which first began eight years ago, and the ongoing legal battle surrounding the State Water Resources Control Board’s decision to implement 40 percent unimpaired flows along the San Joaquin River and its tributaries for the betterment of fish.
Since 2006, California has been releasing periodic reports on how the state should adapt to the potential impacts of climate change. The most recent report is unique in that it also looks at key climate risks from a regional perspective. Our news director Alice Daniel recently spoke with Joshua Viers, a watershed scientist at UC Merced and one of the authors of the San Joaquin Valley assessment.
Although ending groundwater overdraft will bring long-term benefits, it entails near-term costs. We find that only about a quarter of the Valley’s groundwater deficit can be filled with new supplies at prices farmers can afford. The rest must come from managing demand. We estimate that ending the overdraft will require taking at least 500,000 acres of irrigated cropland out of production.
When it floods in California, the culprit is usually what’s known as an atmospheric river—a narrow ribbon of ultra-moist air moving in from over the Pacific Ocean. Atmospheric rivers are also essential sources of moisture for western reservoirs and mountain snowpack, but in 1861, a series of particularly intense and prolonged ones led to the worst disaster in state history: a flood that swamped the state. What would happen if the same weather pattern hit the state again?
In December, the city began delivering recycled water through its purple pipeline to the Tulare Irrigation District (TID) following approval by the Department of Drinking Water (DDW). Under an agreement signed in 2013, the city is obligated to deliver 11,000 acre feet of recycled water to TID per year in exchange for 5,500 acre feet of surface water used to recharge the city’s groundwater. Since 2016, the city has received enough surface water from TID to off set one year of groundwater pumping for the entire city.
It’s shaping up as a wetter-than-usual winter in California, putting to rest fears of another drought hitting anytime soon. Depending on where you live, though, you will still likely face some limitations on how much you can water your lawn this summer.
A federal environmental analysis recommends relicensing the Don Pedro hydroelectric project and accepts a Modesto and Turlock irrigation district plan for well-timed flows to boost salmon in the Tuolumne River. The flows, combined with other measures to assist spawning and outmigrating young salmon, would commit less water to the environment than a State Water Resources Control Board plan that’s unpopular in the Northern San Joaquin Valley.
Felicia Marcus, whose push for larger river flows angered farmers and community leaders in the Northern San Joaquin Valley, won’t continue as chairwoman of the State Water Resources Control Board. Gov. Gavin Newsom named Joaquin Esquivel as chairman of the powerful water regulatory board. … Laurel Firestone, co-founder of the Community Water Center, was appointed as the replacement for Marcus. … Firestone has been an advocate for addressing wells contaminated with nitrates.
While campaigning for president in 2016, Donald Trump promised a cheering Fresno crowd he would be “opening up the water” for Central Valley farmers… Trump took one of the most aggressive steps to date to fulfill that promise Tuesday by proposing to relax environmental regulations governing how water is shared between fish and human uses throughout the Central Valley.
Despite many high priority issues on his plate, one of Gov. Gavin Newsom’s first tests will be how he deals with California’s water challenges and opportunities. Unfortunately, in the last days of his term Gov. Jerry Brown made a bad bargain with the Trump administration and special interests. It’s yet another mess for the new governor to mop up.
