OPINION: Water Supplies Sufficient for 2019 and Beyond

/in , /by /Ramona Sentinelby Jim Madaffer Mentioned: San Diego County Water Authority

A welcome rainstorm in mid-October provided the first significant relief from months of very hot and dry weather — and then the weather turned hot and dry once again. That cycle is a reminder of two important facts of life of San Diego County:

  • On average, we get about 10 inches of rain a year — far less than what we need to sustain our $220 billion economy and 3.3 million people.
  • With continued investments in water supply reliability and water-use efficiency, we can continue to thrive in this amazing place.

As we look toward the rainy season, it’s worth taking stock of why we have sufficient supplies for 2019 regardless of the weather.

OPINION: Here’s What Trump Gets Wrong About California’s Water Supply

/in , /by /Pacific Standard (Santa Barbara)by Kate Wheeling

On Tuesday, President Donald Trump fanned the flames of a long-standing debate in California between the state’s environmentalists and farmers. At the White House State Leadership Conference, Trump called California’s dry and fallow fields “one of the most ridiculous things” he saw on the campaign trail in 2016, when the state was still in the midst of a record-setting drought. At a campaign rally in Fresno that year, Trump claimed the government was “taking the water and shoving it out to sea,” and promised to deliver more water to Central Valley farmers.

North County Water Symposium Highlights Efforts to Ensure Reliability

/in /by

Escondido — The 2018 North County Water Symposium on Wednesday highlighted efforts by the San Diego County Water Authority to ensure regional water reliability for a crowd of about 100 North County business and industry leaders.

Keynote speaker Jim Madaffer, the Water Authority’s newly elected board Chair, reviewed the Water Authority’s historic achievements in water supply diversification. He also discussed continued regional development of water recycling capacity and investments in technology to maintain billions of dollars worth of water infrastructure.

“As the Water Authority approaches our 75th year,” said Madaffer, “we are doing everything we can …  to make sure that we have a resilient water supply for the region.”

The symposium was organized by the San Diego North Economic Development Council. It featured a panel discussion on water supply and reliability for San Diego North County, with a focus on agriculture and housing. Panelists were Greg Thomas, general manager of Rincon del Diablo Municipal Water District; Cari Dale, water utilities director for the City of Oceanside; Eric Larson, executive director of the San Diego County Farm Bureau; and Michael McSweeney, senior public policy advisor for the San Diego Building Industry Association.

Larson highlighted efforts by farmers to increase water-use efficiency and advance recycled water use to support their multi-billion dollar industry. McSweeney said the building industry improves water efficiency when it replaces decades-old homes with new homes that use less water and less energy thanks to modern technologies.

Larson and Thomas say their respective industries share a similar challenge. Larson said fewer young adults today choose farming careers. Thomas expressed the same concerns about the water industry. “There is so much emphasis among high school students on going to college, we aren’t training enough water technology employees” to replace a “silver tsunami” of retiring Baby Boomers, he said.

Madaffer and the panelists agreed that continued dialogue and coordinated efforts among the North County region’s leaders across all economic sectors can drive economic growth while ensuring water efficiency and reliability.

Water Supplies Sufficient for 2019 Demands Despite Hot, Dry Weather

/in , /by

At the start of the 2019 water year, the combination of diversified water supplies and water-use efficiency means the San Diego region has enough water for 2019 and the foreseeable future despite historically low rainfall over the past 12 months.

“It has been very hot and dry, but we have invested wisely in infrastructure and regional water-use remains well below where it was at the start of the last drought,” said Jeff Stephenson, a principal water resources specialist with the Water Authority. “In fact, potable water use over the past three-plus years was 17 percent below 2013, which shows that San Diego continues to live WaterSmart.”

Still, said Stephenson, “we are looking for a wet winter locally, and in the Sierra and Rocky Mountains, to help replenish reserves for future years.”

Water managers use “water years” that run from October 1 through September 30 to track rain and snow. Local rainfall during water year 2018 totaled just over 3 inches at Lindbergh Field – 67 percent below normal and the second-lowest in San Diego history dating back to 1850.

In addition, local temperatures have been significantly above normal for most of the past five years. In many of those months, the average daily maximum temperatures were more than 4 degrees above long-term averages.

Forecasts predict continued warm weather conditions through December

The National Weather Service’s Climate Prediction Center forecasts continued warm conditions for California through December, with a 33 percent probability of above-normal precipitation locally. The U.S. Drought Monitor’s classification of San Diego County as an area of “Severe Drought” is based on weather factors – but it does not reflect water supply conditions.

More than $3.5 billion in regional water investments by San Diego County ratepayers over the past three decades mean water supplies will meet demands regardless of the weather.

New supplies and infrastructure upgrades include the Claude “Bud” Lewis Carlsbad Desalination Plant, which delivers approximately 50 million gallons of potable water per day for regional use, along with a ramp-up of water delivered to San Diego County as part of a long-term water conservation and transfer deal signed in 2003.

Other regional assets include the storage of 100,000 acre-feet of water behind the raised San Vicente Dam due to conservation efforts during the last drought. In addition, many key reservoirs statewide, including Diamond Valley Lake in Riverside County, remain near average levels for this time of year. Significantly, no shortages are expected on the Colorado River system in 2019, though long-term drought conditions continue to be a concern across the Southwestern U.S.

The Water Authority offers several programs, including a Landscape Transformation program rebate, to promote water-use efficiency. Residents and business can also attend free sustainable landscaping classes, and access online videos and tips. To learn more about those resources and others, go to WaterSmartSD.org.

From Serial to Ethernet

In Northern San Diego County approximately 7 miles inland from the Pacific Ocean lies the town of Vista, Calif. Vista was founded in 1882 and quickly grew as its Mediterranean climate proved to be excellent for agricultural homesteaders. During the 1920s, Vista was referred to as the avocado capital of the world. But the town faced many hurdles during its growth including severe drought, a problem that Vista, like the rest of California, faces today. As the area increased in population, the Vista Irrigation District was created in 1923 to ensure a reliable source of water for the naturally arid region.

Geologists are beginning take core samples to collect data for a proposal to raise Shasta Dam by 18 1/2 feet. The Bureau of Reclamation says the samples will be taken over the next few months from on, around and deep within the dam, in order to characterize concrete and geology conditions. The federal government has been studying the idea of raising the dam and enlarging Shasta Reservoir on and off since the 1980s. But the state of California, environmental groups and the Winnemem Wintu Tribe have been and remain opposed.

Current weather patterns and Colorado River water management will result in a drought by the year 2020, affecting communities and farms along the entire Lower Basin, according to officials. Arizona’s water stakeholders, led by Arizona Department of Water Resources and Central Arizona Project, have been engaged for more than two months in crafting Arizona’s approach to the Lower Basin Drought Contingency Plan in an effort to protect Lake Mead, the reservoir formed by Hoover Dam, from falling to critical levels.

During the hot summer months of 2014, East Porterville, Calif., became a poster child for vulnerable drinking water. Hundreds of shallow wells in this unincorporated Tulare County community ran dry in the midst of statewide drought. Some families had to wait years to have running water again, when their homes were finally connected to the city of Porterville’s municipal water supply. While East Porterville’s experience made headlines around the country, the serious drinking-water problems facing other communities across California are just beginning to receive much-needed attention.

US Southwest Set For Water Crisis As Levels Continue To Drop At Lake Mead And Lake Powell

/in , /by /Daily Mailby Cheyenne MacDonald

Two major lakes in the Colorado River Basin that operate as one huge reservoir to supply millions of people with water are drying up, scientists have warned. Water levels at Lake Mead and Lake Powell have been steadily declining over the course of a two-decade drought affecting the region. In addition to the extended dry spell hitting the Colorado River Basin, the water supply is suffering a severe ‘structural deficit,’ in which more water is being consumed each year than can be replenished. More than 40 million people and 7,800 square miles of farmland rely on the Colorado River and its tributaries.

Why San Francisco Is Joining Valley Farmers In A Fight Over Precious California Water

/in , /by /The Sacramento Beeby Dale Kasler and Ryan Sabalow

Originating in a glacier at the eastern edge of Yosemite, the Tuolumne River runs into a man-made roadblock in the towering granite cliffs of the Hetch Hetchy Valley. A massive concrete dam captures its icy water and ships much of it through pipes and tunnels to the residents of San Francisco. Farther downstream, the Tuolumne is halted again, this time by a dam in the oak-covered Sierra foothills. From there, a network of canals spreads the Tuolumne’s waters over mile after mile of rich San Joaquin Valley vineyards, orchards and dairy farms.
