Dire Need for Temperance Flat

Temperance Flat Dam Could Minimize the Devastation of SGMA

By Jessica Theisman, Associate Editor

Mario Santoyo, Executive Director at San Joaquin Valley Water Infrastructure Authority, explained the dire need to build Temperance Flat Dam to California Ag Today recently, and the possible consequences if it is not built.

“With the new groundwater sustainability law coming into play, it is going to basically shut down a lot of farming,” he said.

If farmers cannot prove that they are replenishing the amount of groundwater as they are taking out, they are not going to be allowed to use the groundwater pumps.

“With the continuing extraction of our surface water by the environmental community and by governmental regulations, farming in the Central Valley is in for a world of hurts,” Santoyo said.

The Temperance Flat Dam would give the ability to manage the high run-off water that is otherwise lost into the ocean.

“We are losing millions and millions of acre-feet into the ocean that makes absolutely no sense to anyone,” Santoyo explained.

Temperance Flat would provide additional storage opportunities—up to an additional 1.2 million acre-feet—and will allow farmers to have carryover water from year to year. This will carry the farmers through the dry years, and it will give the allowance to stabilize the groundwater condition.

This dam needs funding from federal, state, and local water agencies.

“The JPA that we represent secured 171 million dollars, which is enough money to pay for the environmental paperwork and initiate the engineering,” Santoyo said.

The remainder of the funds has come in chunks from the federal government through the WIIN Act.

“The bulk of it will have to be the end users, the beneficiaries, i.e. the water agencies,” Santoyo said.

Right now, they are working on the process to evaluate the level of investment that they want to partake in.

“The way this project will work is multidimensional. But the key element will be storage management,” Santoyo said.

The investors would be buying chunks of storage cells in that reservoir to manage.

“In some cases, if you have a bad year in which you have water and others don’t, you’d be able to work something out with them,” Santoyo explained.

“Temperance Flat was a part of the focus when the WIN Act was being put together by Senator Feinstein and Congressman McCarthy,” Santoyo said.

The money allocated is enough to keep the project moving forward on an annual basis.

President Trump signed a memorandum a few months ago, however, Santoyo said, “Since I’ve been involved for a longer period of time, unfortunately, that memorandum that was signed in effect really didn’t do anything.”

Federal courts had already ruled previously that the biological opinions needed to be redone.

“All this memorandum did was just accelerate the study of it,” Santoyo explained.

A resolution on the Delta does not look like it will be here anytime soon.

“That’s why I think that if you have an opportunity to do something positive that doesn’t affect usage of the Delta water you should take it,” Santoyo said.

That’s what Temperance Flat does.

“Three billion dollars represents the full construction of the dam,” Santoyo said.This is the targeted budget for the dam. If the funds can be collected and in time, the dam will be fully operational by 2033.

Letter to California Water Commission on Failure to Approve Temperance Dam

CWC Decision is a Black Eye to State

Editor’s note: Valley legislators sent the attached letter to the CWC last week, reflecting both disappointment and concern over the CWC WSIP process as it relates to the Temperance Flat Reservoir Project. The letter asks for a reconsideration for the TFR ecosystem evaluation.

Clearly, we appreciate all our Valley legislators who have fought so hard for this project for many years. This letter at a minimum puts on the record their thoughts on how the CWC handled the TFR project.

May 17, 2018

California Water Commission: Mr. Armando Quintero, Chair, & Mr. Joe Yun, Executive Officer

P.O. Box 942836, Sacramento, California 94236-000

Dear Mr. Quintero, Mr. Yun and Commission  Members:

On May 3, 2018, The California Water Commission took action, perhaps the most definitive and historic action with regard to the Water Storage Investment Program (WSIP) state bond funding applications.

As members of the California Legislature, we have watched and participated in this entire application process. All Californians would benefit from water storage projects this money is intended to fund. However, this investment has been stymied by the commission staff’s narrow determination. The people we represent have expected a great deal of positive leadership from the Water Commission and we echo the public’s disappointment in how the review process has unfolded.

During the initial review of WSIP project applications, many of us joined in calling into question the policy and procedures of the application review process. From the beginning, we had concerns that the process developed by commission staff and the information provided would not adequately account the benefits of water storage projects throughout the state. Despite our concerns, little was done to address the problem resulting in six of the project scores receiving “O” benefits.

Temperance Dam
Mario Santoyo is Executive Director of the SJV Water Infrastructure Authority, which presented the Temperance Flat Dam Proposal to the California Water Commission​.

In 2008, the EDT model was selected by the state and federal agencies responsible for implementation of the San Joaquin River Restoration Program (SJRRP)—namely the U.S. Bureau of Reclamation, the U.S. Fish and Wildlife Service, the U.S. National Marine Fisheries Service, and the California Department of Fish and Wildlife (CDFW). In the Quantitative Fisheries Model Selection Recommendation Process, 2008, the SJRRP agencies state that EDT was rated ” … as the most appropriate quantitative fish population model for the SJRRP.” This report also states that “the EDT model is a framework that views salmon as the indicator or diagnostic species for the ecosystem. The salmon’s perspective (i.e., its perception of the environment) becomes a filtered view of the system as a whole.

The EDT framework was designed so that analysis made at different scales (i.e., from tributary watersheds to successively larger watersheds) might be related and linked. Biological performance is a central feature of the framework and is defined in terms of three elements: life history diversity, productivity, and capacity. These elements of performance are characteristics of the ecosystem that describe persistence, abundance, and distribution potential of a population. This analytical model is the tool used to analyze environmental information and draw conclusions about the ecosystem. The model incorporates an environmental attributes database and a set of mathematical algorithms that compute productivity and capacity parameters for the diagnostic species. …”

In 2014, the U.S. Bureau of Reclamation selected the EDT model for application to the Upper San Joaquin River Basin Storage Investigation—the federal feasibility study of Temperance Flat Reservoir—to quantify benefits. Prior to its application, Reclamation commissioned a scientific peer review of the EDT model to confirm the suitability of its use for quantifying benefits. It is our understanding that when the SJVWIA team asked if there were any models that could be used in place of the EDT, the CWC staff declined to respond. This is of clear concern and demonstrates the inconsistencies within the information provided by commission staff.

From the San Joaquin Valley’s perspective, the outcome of this process is a black eye for the state. The two-thirds threshold for Proposition 1 in 2014 would not have been met without the support of the San Joaquin Valley. Despite the bias by some opponents against large-scale storage projects, the language in AB 1471intentionally included Chapter 8 (Provision (a), section 797.1, page 22) to clarify that the Legislature’s intent for the $2.7 billion allocation was for  surface water storage projects with an emphasis on Sites and Temperance Flat Reservoir based on the CALFED Bay-Delta Program Record of Decision, dated August 28, 2000 (Section 2. Decision, 2.2 Plan for Action, 2.2.5 Storage, pages 42 through 45). We the members of the Legislature believed that by voting for Prop 1 funding that all projects including controversial storage projects in the CALFED Bay Delta Program would be given a fair and accurate evaluation in order to meet the overall water management strategy for the state.

In closing, we insist that the Water Commission reconsider its acceptance of the staff recommendation on the Temperance Flat Project’s ecosystem scoring or at the minimum direct the staff to go back and re-evaluate the application’s ecosystem public benefit utilizing the Ecosystem Diagnosis and Treatment (EDT) model cited in the Water Commission’s Technical Reference Document as being acceptable for use in the analysis required by the application.

Sincerely,

(Letter was signed by nine Valley state senators and assembly persons.)

Officials Angered Over Temperance Flat Lack of Funding

The Will of The People Was Ignored

By Patrick Cavanaugh, Editor

Agricultural leaders from cities, along with state and federal officials representing the Central San Joaquin Valley, are reeling with anger and disappointment with the California Water Commission’s failure to fund the Temperance Flat Dam storage project.

California Water Commission members facing the room, with staff at table in front of them. The staff made all decisions based on NRDC and CA Fish and Wildlife recommendations, killing Temperance Flat funding.

“The California Water Commission have ignored the facts and their own guidelines and have ignored the will of the people,” said Lee Brand, mayor of Fresno. “We believe the voters, especially those in the Central Valley, overwhelmingly passed Proposition 1 where there was an expectation that their hard-earned money would be spent to help build water storage.”

“We desperately needed the Temperance Flat project. It will help us secure our water supplies against the droughts we know surely come,” Brand said.

The push to get funding for Temperance Flat dam was truly a valley-wide effort, with supervisors from Fresno, Kings, Madera and Merced counties, along with many cities and water agencies.

“Voters not just in the Valley but across the entire state should be upset over this decision. It is unthinkable that the Water Commission did not understand the benefits of the temperance flat project,” Brand said.

“Clearly all of us … are disappointed and clearly many of the voters in this valley are angered because we have been overlooked in terms of the water needs that are so essential for our valley,” said Jim Costa, D-CA 16th District, which includes Fresno.

“The Valley needs a reliable supply of water, and we supported this initiative on the basis that we would gain a more reliable supply of water. And clearly the recommendations of the Water Commission who took their staff’s lead was a very, very big disappointment for me. And I think all of us,” Costa continued.

“We’re not given up. That’s the bottom line. We’re not giving up,” he said.

Travis Allen’s Plan for Agriculture

Allen Says Regs Hurting Farmers

By Jessica Theisman, Associate Editor

California has general elections coming up on November 6th, and campaigning is already underway for the June 5th primary. California Ag Today recently met with Travis Allen, a state assemblyman running to be the next governor of California.

“One of my 5 point plans is very simple: to complete the California state water project,” Allen said.

One of his goals is to help complete the water project with more water storage in California. (Editor’s Note: We were not able to reach Travis Allen regarding the failure of the California Water Commission in funding Temperance Flat Dam.)

Califonia Assemblyman Travis Allen is Running for Governor

Allen wants to, “cut California’s taxes, get tough on crime and repeal the soft-on-crime laws of Gov. Jerry Brown.” Other goals include fixing the roads, expanding freeways, and repealing the gas tax without any new taxes.

“We are going to fix our broken education system,” he also said.

Allen wants to ensure there is enough water for the Central Valley.

“We have all of these extreme environmental regulations that are literally regulating our farmers out of business,” he said.

The State Water Resources Control Board has taken a heavy-handed approach in the valley and it affects everyone across California, not just the people who live in the Central Valley.

“Remember, the fruit and vegetables that are grown right here in the Central Valley are enjoyed not only throughout California but throughout the country and throughout the world,” Allen said.

Temperance Flat Denied Funding

All Hope Dries Up

By Patrick Cavanaugh, Editor

Again, it came down to fish, specifically Chinook salmon, that forced the proposed Temperance Flat Dam out of the race for Proposition 1 funding for building new water storage projects.

Mario Santoyo and Temperance Flat Denied Funding
Mario Santoyo fought hard for Temperance Flat Dam funding.

For more than 20 years, the Temperance Flat Dam proposal was passionately advocated with unwavering support by Central Valley cities and the San Joaquin Valley Infrastructure Authority (SJVIA) who were behind the application. Temperance Flat came crumbling down Wednesday at the California Water Commission (CWC) meeting in Sacramento on the second day of discussion.

On Tuesday, CWC staff members assigned to crunch the Public Benefit Ratios for the project were solidly encased in concrete, refusing to grant the project any consideration for its ecosystem restoration benefits. The Dam would provide critical cold water to flow down the San Joaquin River, thus helping the salmon spawn.

CA Water Commission kills Temperance Flat funding
CA Water Commission denied funding for Temperance Flat Dam.

And while the official public benefit calculation came up short today, proponents already saw that the project was already on life support Tuesday, with a dire prognosis.

“Stunned is an understatement,” said Mario Santoyo, executive director of the SJVIA, who has worked for more than 18 years on the project. “Temperance Flat is the most critical water project ever proposed for the Central Valley, which is ground zero for significant water shortages that will not go away.”

It all boiled down to the Ecosystem Diagnosis and Treatment (EDT) model that was approved by Bureau of Reclamation and the California Department of Water Resources. Despite both approvals, that model did not jive with the Commission staff’s model, which undervalued the project’s public benefit ratio, killing the opportunity for Temperance Flat Dam to receive funding of more $1 billion for construction.

“We are working in an area of great uncertainty in professional judgment,” Bill Swanson, vice president, Water Resources Planning & Management for Stantec, a global planning and engineering firm, who presented data for the SJVIA. “We do not have fish in the river. We do not have empirical data. The only issue available to us is a comparison of how the system would respond to changes in flow, temperature and habitat,” Swanson said.

“That’s the reason we used the EDT model, the same model that the Bureau of Reclamation has used in their models of flow,” Swanson explained. “The SJVIA’s challenge was how to take the results of that model and analyze them to a level of detail that distinguishes the precision that we might want to have around the results,” said Swanson.

Bill Swanson
Stantec’s Bill Swanson advocated for Temperance Flat Dam funding.

“I’m very disappointed with the way they scored a great project that needed to be built,” noted Santoyo. “And I am not happy about one commissioner from Orange Cove who stabbed us in the back and scolded us on why we did not meet the Public Benefit Ratio. We did meet and exceed that ratio, but the CWC disagreed with our ecosystem restoration model that had been used by both the state and the feds.”

Several Water Commissioners publicly wrangled with their staff on how they could make the project work. They sought areas to increase the project’s cost-benefit evaluation to get it funded.

Commissioner Joe Del Bosque read the ballot text of Prop 1, approved by California voters by 67 percent in 2014. He reminded those present that voters expected a water storage project to be built, adding, “We need to find more certainty in order to get Temperance Flat built.”

Commissioner Daniel Curtain distinguished two parts to the discussion—physical and monetary. “Take a look and see if there is a physical benefit for ecosystem restoration. Finding a potential benefit and attaching a potential monetary benefit could be helpful,” he said.

The project was also short on points for recreation opportunities on what would be a new lake behind the 600-foot high dam east of Fresno, behind Friant Dam. Commissioner Joseph Byrne said he hoped for more thought given to the recreation cost benefit. “Intuitively, zero benefit does not make sense. We need a higher level of confidence in the estimated recreation cost-benefit,” he said.

CWC staff stipulated that while the newly created lake behind Temperance Flat Dam would accommodate boating activity, the lack of camping, hiking, and other activities within the existing San Joaquin River Gorge neutralized any recreation benefits.

If built, the Temperance Flat Reservoir would contain 1.26 million acre-feet of new water storage above Millerton Lake, northeast of Fresno. Temperance would have helped provide a more reliable supply of fresh drinking water for disadvantaged Valley communities. It would have enabled below-surface groundwater recharge, addressed extreme land subsidence and provided critical help to farmers facing severe groundwater restrictions due to the Sustainable Groundwater Management Act (SGMA).

Santoyo said the SJVWIA spent more than $2 million on the California Water Commission application, utilizing what he said were the most qualified engineers to develop the technical data required by Commission staff. The U.S. Bureau of Reclamation, which administers California’s Central Valley Project for the U.S. Department of the Interior, has invested more than $38 million in studying the project. Santoyo said those studies supported the finding that the selected Temperance Flat site is the most preferred location for such a crucial project.

Water Storage Is Big Issue

ACWA Supports Storage for Entire State

By Patrick Cavanaugh, Farm News Director

Water storage is a big issue in California. Tim Quinn, the Executive Director of the Sacramento-based Association of California Water Agencies (ACWA), which represents water agencies throughout the state, recently spoke with us about California water and the importance of water storage in the future as well as his experience working with water agencies in such diverse parts of the state.

“My association strongly supports the notion of a comprehensive plan, and they want it to work for everyone,” Quinn said. “In my world, I do not have the northern wanting to sell the southern route or the ag areas wanting to sell to urban dwellers or the reverse.”

Tim Quinn

But Quinn does describe some tension in the state. “There is a lot of east-west tension in this state. It use to be north and south water, and it’s still there, but not as much as east-west, the coastal demographic,” Quinn said. “It’s the coast versus inland and conservative agricultural California, and so we’re working on building bridges in that regard, but my association represents professional water managers and their boards of directors in the state of California, and they are united in wanting a comprehensive plan to move forward that works for everyone.”

Quinn said that one comprehensive plan that’s beneficial to everyone is water storage. The Association of California Water Agencies doesn’t necessarily promote the building of one specific dam, but instead it promotes improving water storage as a whole.

“If you look at the list, it doesn’t say Temperance Flat and doesn’t say Sites. It definitely says storage, and we strongly support the process that’s going on with the California Water Commission to find the best storage projects for California,” Quinn explained.

“I don’t think we’ll build just one or just two or three storage projects; I think will build four or five or six projects and will build below the ground projects as well,” he said. “My organization is strongly supportive of that comprehensive plan moving forward representing the entire state. I’m not going to say do Temperance Flat and don’t do this one, but projects like the Temperance Flat are part of our future, and I think you’ll see them moving forward.”

Supporting Temperance Flat to Increase Groundwater Recharge

Building Above Ground Water Storage Enables Groundwater Recharge

By Laurie Greene, Founding Editor

Dramatically helping to recharge groundwater storage is one of the major benefits of the proposal to build Temperance Flat Dam behind Friant Dam, located to the north and east of Fresno. The new dam would triple the storage that is currently available with Friant Dam. Mario Santoyo, the executive director of the San Joaquin Water Authority, is helping the organization prepare the package to submit to the Water Commission by the August 14 deadline.

“We will be making timed releases to various water districts and amenities that will have groundwater recharging basins,” Santoyo said. “First, we need storage and then some time to move above ground water to underground storage. This is a physics necessity and directly counters those who argue we should not build above ground infrastructure if we need only underground storage. Well, if you don’t have above ground water storage, you ain’t putting any below. It is as simple as that.”

Water in Friant-Kern Canal

“There are two water conveyances from Friant and [the proposed] Temperance Flat Dams: the Friant-Kern Canal – the longest of the two primary canals – and the Madera Canal. Friant moves water south to Bakersfield, and Madera conveys it north to Chowchilla.”

“We will have one of the strongest applications to receive monies,” said Santoyo, assuring that the water authority will receive the package on time.

Now this is important,” Santoyo stressed. “A new video, ‘Build Temperance Flat,’ is now on YouTube. The video aims to educate Californians on the importance of building Temperance Flat Dam.” Santoyo urges those who are on social media to send the URL: https://www.youtube.com/watch?v=f30o_dQNmn8  “to as many people as you can!”

Temperance Flat Dam is Needed

Temperance Flat is a Sure Way to Improve California’s Water Infrastructure

By Patrick Cavanaugh, Farm News Director

Mario Santoyo is the Executive Director for the San Joaquin Valley Water Infrastructure Authority. He spoke to California Ag Today about Temperance Flat, a proposal supported by the Joint Powers of Authority composed of five counties: Merced, Madera, Fresno, Tulare and Kings County. In addition to those counties, there are representatives from the eastern side cities, (Orange Cove) and western side cities, (Avenal)

“We also have water agencies, such as the San Joaquin River Exchange Contractors,” Santoyo said. “The JPA is also in the process of dealing with membership requests by Friant Water Authority and the San Luis Delta Mendota Water Authority.”

Mario Santoyo

“You can see we’ve got a pretty elaborate team as far as the authority,” Santoyo said. “It was put together in order to pursue funding opportunities both by the state of California and the federal government to build revenue leading towards the construction of the Temperance Flat Dam and Reservoir project, which will be located just north of Friant Dam on Millerton Lake, and actually would be built in Millerton Lake … expanding that reservoir.”

The five counties got together on this because they understand fully the importance of creating a more reliable water supply for the area. Santoyo said, “It was proven to be a problem when we had the five-year drought and the Valley had to exercise its groundwater pumping, which plummeted the groundwater levels so much that … it actually resulted in what is now the Groundwater Sustainability Law.”

“So there’s no question this project is greatly needed, and the irony is that this year, coming out of a five-year drought, we’ve got high runoff, and the Bureau of Reclamation had to make flood releases in order to not exceed the capacity at Friant Dam/Millerton Lake,” Santoyo explained. “We fully expect that they will have made up to 2.5 million acre feet of releases down the river to the ocean. Then if you stop and think about what that means, it basically you could roughly say it’s about two years’ worth of water supply for the eastern side of the Valley.”

“There are those who would argue that we would never fill up the Temperance Flat Reservoir,” Santoyo said. “Well, not only have we done it twice this year, we also have a history—a long history—of this … [being] the common scenario.”

When there is high runoff water, it doesn’t come in little bits, it comes in huge amounts. “I think we looked at the record, and 50% of the time that we have high runoff, we usually have to make flood releases in excess of one million acre feet, so that’s why the size that was determined for Temperance Flat was just a little bit over a million acre feet,” Santoyo said.

“Now having that, it’s actually 1.2 million acre feet that it adds to the system. When you add it to … the balance of what’s left with the original, we’re close to 1.8 million acre feet,” Santoyo said.

“It will triple the capacity of Millerton, ensuring that for the future, that [there is] a chance to maximize the available water supply for the cities, for the farms, and most importantly, to recharge the groundwater and put us back into a level that we’re stable and that residents, farmers and others can use that groundwater and not be restricted by the new groundwater sustainability laws,” said Santoyo, adding, “If we don’t solve that problem, the world is going to change dramatically for our farmers, number one, and it will have an immediate effect also on our cities.”

Santoyo describes the recharge opportunities. “What we’ll be doing is with Temperance Flat, we will be making timed releases to various water districts and entities that will have groundwater recharging basins, and they will be syncing it, but you need time,” he said.

“You need storage, and you need time to be able to move water from above ground to below ground. That’s just a physical necessity, and that’s part of the argument against those that argue, ‘Don’t build above, you only need below.’ Well, if you don’t have water above, you aren’t putting it below. It’s just as simple as that,” Santoyo explained.

Temperance Flat would be ideal for the state of California. “The Friant-Kern Canal is the longest of the two primary canals. The other one is the Madera Canal. The Madera moves it north to Chowchilla. The Friant moves it south to Bakersfield, so yeah, those are the primary conveyance systems for farmers and cities,” he said.

Recently a video that educates the public on the value of Temperance Flat, released on YouTube called Build Temperance Flat. We ask all who are active on social media to grab a link of the video and post it on Facebook and Twitter as well as other social media platforms.

Final Feasibility Study Begins for Temperance Flat Dam

Temperance Flat Dam Would Provide Groundwater Relief, Jobs

By Patrick Cavanaugh, Farm News Director

Mario Santoyo, executive director, San Joaquin Valley Water Infrastructure Authority (Joint Powers of Authority), described the major and historic event held last week at the Friant Dam regarding the Temperance Flat Dam and California’s future water supply.

“At the event,” Santoyo said, “a Memorandum of Understanding (MOU) between the U.S. Department of the Interior, Bureau of Reclamation and the Joint Powers Authority, basically defines what the scope of work is going to be. In essence, it is full cooperation between their technical people and our Joint Powers Authority.  Our people are working on tailoring the application to the state to optimize how much money we get from them. Keep in mind, we’re talking big dollars here; we’re not talking a million or a hundred million.”

Joint Powers of Authority
At Friant Dam, a Memorandum of Understanding was signed between the Department of the Interior, Bureau of Reclamation and Joint Powers Authority for the Temperance Flat Dam.

Santoyo hopes to receive $1B in funding for the Temperance Flat Dam, although “it is going to cost somewhere around $2.8B. The maximum you could ask from the state is $1.4B. We don’t expect to be getting that because there is a lot of competition and there’s not enough dollars to go around. We’re hoping to shoot for somewhere around $1 billion,” he stated.

“In parallel with our efforts with the state,” Santoyo explained, “we’re working on the federal side with our senators and our congress members to obtain what they call a federal construction authorization—which allows the federal government to move ahead with this project. Then we work on appropriations,” he said.

Santoyo said the funding necessary to complete and complement dollars from the state will be procured in the same fashion as have projects in the past. “The Bureau of Reclamation typically funds the construction of a project and then recovers the cost through long-term water supply contracts or adjustments to existing water supply contracts,” he stated. “In this case, it would be adjustments to existing water supply contracts.”

Santoyo also noted preliminary feasibility studies are underway. Those already completed triggered the final feasibility report, “which is going through a final upper management review before being released to the public. I think we are all pretty confident it will come out in a very positive manner. I would expect that in the next sixty days,” he said.

The expected completion of the project varies. Santoyo estimated physical completion within five years,” but it has to go through design and environmental paperwork, plus legal challenges could cause setbacks as well. By the time you’re good to go, you’ll end up having this project built in probably under 15 years,” he said.

DAM CREATES NEEDED JOBS FOR VALLEY RESIDENTS

Nevertheless, Santoyo said the benefits of the Temperance Flat Dam project is to creates an economic boom and an increase in available jobs. “You’re going to be spending about $3B here for materials, labor, and everything that goes into it. It will be an economic boom; and once it’s built, we get more water reliability, creating a better situation for the farmers, and that creates employment. I wouldn’t look at waiting 15 years, it starts as soon as we start building,” he said.

“The best year for Temperance Flat is when we have high runoff periods, and we have those frequently,” Santoyo elaborated. “What I’ve determined is that there’s a 50% shot every time we have one that we will be dumping more than a million acre-feet into the ocean. That’s equivalent to a full-year of water supply for the east side of the valley. That’s a lot of water.”

DAM PROVIDES GROUNDWATER RELIEF

“The fact is, without this project, we will not be able to meet the ground water sustainability laws that exist because this water will be necessary to move underground to all these regions,” he said. “Right now, as it stands, San Joaquin River Settlement has taken away the Class II water that used by the Friant contractors to replenish the groundwater. Unless we have a means of replacing it, and that would be through Temperance Flat, we’re going to encounter very serious problems,” Santoyo noted.

“Take the typical example of a year in which we can save a million acre-feet in storage. We are not going to keep it there,” he said. “We are going to move it via the canal systems to the various groundwater recharging basins,” which capture and replenish underground water. “It’s not a matter of whether groundwater storage is better [or worse] than above-ground storage; they work in conjunction with each other to maximize storage.”

DAM SERVES A PURPOSE IN TIMES OF CRISIS

“There are a lot of conversations about the San Andreas Fault rumbling. If we had an earthquake, we could have a seismic event in the Delta,” Santoyo said. “What differentiates this project from all the other projects is that we could take Temperance Flat water and go north via the San Joaquin River to the Delta, or south via the Friant-Kern canal, across the valley canal to the California aqueduct then subsequently down to southern California,” he said.

“In a scenario of Delta failure, in which water was no longer moving to the millions of people in Southern California, that would be a crisis,” he stated, “they would be looking for help in any way, shape, and form. Temperance Flat could do that. That’s one of the public benefits being looked at by the California Water Commission, in a category called emergency services. That was written in there specifically because of Temperance’s capability.”
