New Oxygenation System to Improve Reservoir Water Quality

The City of San Diego’s Public Utilities Department last week took a major step toward completing an innovative project to improve water quality in Lake Hodges. A newly installed oxygenation system, designed by city engineers, will introduce highly oxygenated water to the bottom of the reservoir to reduce the accumulation of excess nutrients and harmful algae growth.

The increase of nutrients and algae in the water has been caused by human activities in the watershed upstream of the reservoir, including residential and commercial development, agriculture, and land clearing. Degraded water quality can restrict the ability to move water in and out of the reservoir.

Trump Jump-Starts Repairs for Sinking California Canal. But Who Will Pay?

The Trump administration is jump-starting a plan to repair a badly sinking canal in the San Joaquin Valley, a year after California voters rejected a bond measure that would have had them pay for the project.

The U.S. Bureau of Reclamation said Tuesday it will begin studying the environmental impact of fixing a 323-mile stretch of the Friant-Kern Canal — a critical water artery on the Valley’s east side. The federal agency said the repairs are needed to boost water deliveries to 1 million acres of farmland that have been dramatically reduced because of the sagging canal.

San Diego, IB Officials Calling for Federal Action on Tijuana River

A group of local officials from around the county introduced a resolution Tuesday calling on the federal government to take action to stop cross-border sewage flows in the Tijuana River Valley.

The group of officials — including San Diego Mayor Kevin Faulconer, Imperial Beach Mayor Serge Dedina, Port of San Diego Commissioner Dan Malcolm and county Supervisor Greg Cox — held a news conference in Imperial Beach to introduce a list of recommended actions, which will be voted on by multiple city councils and boards in the coming weeks.

Water Industry Takes Major Step Towards Becoming Carbon Zero

Working with two international consultancies, Ricardo and Mott MacDonald, the sector will develop a comprehensive action plan detailing the measures the industry will deploy to achieve zero carbon emissions over the next decade.

The water industry is the first industrial sector in the UK, and one of the first major sectors in the world, to commit to a carbon zero future by 2030. The goal forms part of the industry’s Public Interest Commitment (PIC) released earlier this year with the carbon zero goal one of five stretching social and environmental ambitions.

Water Restrictions in Poway Likely to Extend Through Friday

POWAY —  The boil-water advisory that Poway has been under since the weekend will likely be lifted on Friday, Poway Mayor Steve Vaus said Tuesday night just prior to the start of a City Council meeting.

Vaus said tests continue to show no contamination of the city’s water supply, but state regulators are requiring two more days of testing before giving the all clear.

Regional Agencies to Vote That Federal Government Must Act on Tijuana River Valley

Continuing their push to end a decades-long environmental crisis, San Diego regional leaders announced today that several agencies and local cities will vote to recommend actions for the federal government to take to eliminate transboundary flows in the Tijuana River Valley.

The resolution – to be adopted by several city councils and boards over the next several weeks – solidifies the most urgent needs that regional leaders request from the federal level to address the underlying causes of the sewage, sediment, and trash that have contaminated San Diego land and waterways for decades.

Fishing Groups Sue Federal Agencies Over Latest Water Plan For California

The fracas over California’s scarce water supplies will tumble into a San Francisco courtroom after a lawsuit was filed this week claiming the federal government’s plan to loosen previous restrictions on water deliveries to farmers is a blueprint for wiping out fish.

Environmental and fishing groups sued the the National Marine Fisheries Service and U.S. Fish and Wildlife Service Monday for allegedly failing to protect chinook salmon, steelhead trout and delta smelt.

Two More Rounds of Rain, Mountain Snow Ahead For California Into This Weekend

California will receive two more rounds of rain and mountain snow through this weekend, continuing a stormy period that kicked off before Thanksgiving.

For now, drier conditions have developed and generally will be in place for most of Tuesday.

San Diego Got More Rain Than Seattle in November

Normally sunny San Diego got more rain than Seattle last month, a reverse of what residents of both West Coast cities have to come to expect.

The National Weather Service recorded just under 3 inches of rain with their monitoring station at Lindbergh Field this November, making it the wettest November on record for San Diego.

Trading Water: Can Water Shares Help Save California’s Aquifers?

California is by far the United States’ most populous state, as well as its largest agricultural producer. Increasingly, it is also one of the country’s most parched places.

But Edgar Terry, a fourth-generation farmer in Ventura County, just outside Los Angeles, thinks he has a key to reversing worsening water stress: establishing tradeable rights to shares of fast-depleting groundwater aquifers.

Doing so would turn aquifer water into a more valuable asset that could be traded on a market, similar to “cap-and-trade” systems that have been set up to regulate air pollution, conserve fisheries and manage other such common resources.
