Atmospheric Rivers Hit California

Many Atmospheric Rivers Hit State

By Patrick Cavanaugh, Farm News Director

California needs an average of three atmospheric rivers annually to reach its average yearly rainfall. So far this year, the state has seen an incredible 46 atmospheric rivers. This intense rainfall has pushed much of California out of longstanding drought conditions.

California Ag Today spoke with Steve Johnson, a private meteorologist for farmers in California. We discussed atmospheric rivers (AR) and the abundance of rain California has seen in late winter and early spring.

“We had four very big AR flows, and that made a big difference. I think we’re up to 46, and that’s what has made the big difference this year,” Johnson said. With the additional 41 smaller AR, we have seen a very wet California; it is an astounding amount of atmospheric rivers.

Johnson explained that because the storms have been so difficult to predict, it has made things difficult for farmers planning their season. “This year, there was no signal at all. These storms crept up on us this winter. It was very, very dicey for forecasting,” he said. “The year was difficult because some of these storms – in fact the big ones – even though they showed up in the 14, 16-day period, they didn’t look gigantic until about day seven or eight. Then they start gaining and gaining and gaining, and by day four or day five they looked monstrous. Well, that’s not very much time to prepare.”

Johnson noted that these unpredictable storms were caused by an anomaly in the Pacific Ocean that is a remnant of last year’s El Nino. “The predominant reason that we kept getting these atmospheric rivers has been the fact that the sea surface temperatures across the Pacific Ocean have been in a very unusual anomaly,” he said. “They’ve been cold in the Gulf of Alaska, and we have a leftover bit of warmth from last year’s record-setting El Nino that has spread north to just west of the California coast – very warm waters that go all the way over to Japan.”

“If you take a look at the differentiation between the cold water in the Gulf of Alaska versus the warm water, the anomalies between Japan and California, that has created a zonal flow since October.

“Those atmospheric rivers have been grabbing a lot of moisture coming up from that warm water off the California to the Hawaii coast, and then coming into California. It’s just been one right after another,” Johnson said.

Record Enrollment at UC Davis College of Agriculture and Environmental Sciences

UC Davis College of Agriculture and Environmental Sciences Really Rocks!

By Patrick Cavanaugh, Farm News Director

Helene Dillard, dean, UC Davis College of Agriculture and Environmental Sciences, is pleased with the big numbers of students attending the top-ranking College of Agricultural and Environmental Sciences.

“It’s really rocking,” said Dillard. “We’re doing very, very well. We have one of the largest numbers of incoming students ever in the entire university. Our College has peaked out its 7,300 undergraduates. We’ve never had that many at one time.”

Why the increased interest in studying agriculture? Dillard said, “We think what’s moving that needle is that everyone is interested in food. They are interested in agriculture. And they are really interested in that intersection between agriculture and the environment. We have a record number of students that just cannot wait to come on board. We are really thrilled with how smart they are and how eager they are to learn.”

Among the many courses offered by the College, Dillard said Animal Science classes are probably among the most popular. “But of course, beer classes and the coffee class are really popular too. But right now, I’m seeing tremendous interest in agricultural economics and in animal science, to become veterinarians and ranchers, plus specific academic interest in poultry and sheep.”

“Again, those are all things that UC Davis does, so we’re really excited. We’re also seeing a lot of interest in plant sciences, more on that sustainable and food systems and our viticulture and enology program’s growing as well.

Livestock Economics for Western Producers

Livestock Economics: What Attributes Bring Higher Prices?

By Laurie Greene, Editor

At the 100th Annual California Cattlemen’s Association (CCA) & California CattleWomen’s (CCW) Convention last week in Sparks, Nevada, Tina Saitone, cooperative extension specialist, UC Davis Department of Agricultural and Resource Economics, described her research on rangeland and livestock economics. “Primarily, my focus has been on cattle — beef cattle to date — but I’ve also started some projects recently with sheep producers and the predator interactions they have specifically with coyotes. I am examining whether or not [producers] can use nonlethal depredation methods to mitigate those losses.”

“Right now, I have been concentrating on marketing characteristics of cattle,” she said. “I study those practices employed by producers, such as when they wean their cattle; how many vaccinations they have; whether they market [their cattle] as natural, grass-fed, or organic; and the impact that [these choices] have on their prices.”

Tina Saitone, cooperative extension specialist, UC Davis Department of Agricultural and Resource Economics

Interestingly, Saitone and her colleagues have mainly been using satellite video auction data. “Western Video Market Auction actually held their auction this month here in Sparks, Nevada because they can do it at different locations all the time. So, we use that data to figure out cattle characteristics and then determine the marginal impact that each of those characteristics has on price,” said Saitone.

Characteristics such breed, frame score, flesh score, and weight, are definitely controls in Saitone’s research model because those are main drivers of price. “But what we want to do is figure out — holding all those things constant —if a producer raises their cattle natural, what kind of premium does that bring them? We’re really looking for that incremental difference.”

One might expect certain factors such as natural or organic, to deserve a higher price, but there always has to be a buyer. “Right now, when prices are low relative to 2014 and early 2015, ranchers do have some opportunities to get some higher prices in what we would call niche markets. Consumers are increasingly demanding a wider range of characteristics. They want grass-fed. They want organic. They want natural, no hormones. All of these are what we would call credence attributes. If you go to the grocery store and you taste a steak, you probably don’t know if it was raised natural.”

Accordingly, the industry has third-party certification to assure consumers that when they pay a higher price for that product they are actually getting those traits. “Farmers actually have the ability to fill some of those niche markets that consumers have created with their demand and possibly get higher prices than just selling into traditional commercial channels.”

The data that Saitone has been looking at from Western Video is focused on Western states, including California. Certainly, location places Western producers at a persistent disadvantage because the majority of the processing capacity is in the central part of the country, with Nebraska being the hub. Saitone said, “When you think about cattle being raised in California having to be transported all the way to Nebraska, some 1600 or 1700 miles, not only do you have the cost associated with that transportation, but you also have shrink; you have mortality.

Postcard Campaign to Stop Additional Pesticide Regulations Near Schools

Call to Growers: Join Postcard Campaign to Stop Additional Pesticide Regulations Near Schools before Friday, Dec. 9

By Brian German, Associate Broadcaster

Proposed DPR Regulations

“The proposed California Department of Pesticide Regulation (DPR) further restricting growers from applying crop protection products near schools is unnecessary,” noted Kelly Covello, president of the Almond Alliance of California, which advocates and lobbies for the almond industry.

“Basically, this proposed rule is going to add a layer of unnecessary regulation. It proposes restricting pesticide applications within a quarter mile of schools and daycare centers between Mondays and Fridays, 6am to 6pm,” said Covello. She noted there are already regulations in place to protect both the community and the applicator.

Likewise, Colleen Cecil, executive director, Butte County Farm Bureau, said, “We’re very confident in the regulation that currently exists and the responsibility that landowners take when it comes to spraying anywhere. There are rules in place and these rules work.”

“The environmental community has done a bang-em-up job at fear-mongering, period. They believe they can take pictures of kids next to fields and make the farmer the bad guy. Nothing can be further from the truth,” Cecil said.

“Nothing is more important than the health and safety of people,” noted Ceil. “As stewards of the land, farmers already do everything in their power to mitigate risks involved in agriculture and the application of pesticide is no exception.” Cecil added, “The puzzling part of the proposed regulation is that DPR have stated themselves that they were ‘unable to quantify the benefits’ and that ‘any health benefits of the prohibitions are unknown.'”

Postcard campaign to stop additional pesticide regulation near schools

Call for Growers to Take Action

“We have joined California Farm Bureau Federation (CFBF) and other organizations that are working on this issue,” said Covello. “One of the main calls to action for grower engagement with DPR is CFBF’s postcard campaign. If you would like postcards to share with your grower network, please email staff@almondalliance.org or simply print from the Postcard PDF document and mail directly to DPR (contact information is on the last page of the PDF document). A high volume of input will be critical.

Growers can also sign and share CFBF’s petition. Farm Bureau will deliver the petitions to DPR before the comment period closes on December 9.

“This [proposed regulation] really is unnecessary,” said Covello. “There is no science. There is no injury or illness that has sparked the need for new regulations. We are really hoping we can get our growers engaged by sending in a postcard or sending in comments. Again, growers can contact the Almond Alliance by email at staff@almondalliance.org and by phone at (209) 300-7140.

“We would be happy to get you a postcard,” Covello said. “We can also email it to anyone. So please help us in this fight to stop unnecessary regulation.”

Algae in Soils Increases Soil Health, Better Crops

Is Algae in Soils a New Frontier in Plant Health and Yield?

By Patrick Cavanaugh, Farm News Editor

Could applying microalgae to the soil boost yield and strengthen plants? We spoke to Len Smith, chief business office, Heliae Development LLC., based in Gilbert, Arizona, in the southeast Phoenix metropolitan area. “Heliae is a company that is dedicated to unlocking the potential of microalgae,” said Smith. “We’ve been in business now for over eight years. We hope to be able to deliver microalgae products in a lot of areas, including in plant agriculture.”

“While we work with hundreds of algae species, the algae we are currently marketing for plant agriculture is a green algae. It is actually subject to genetic classification so I couldn’t even tell you the exact species at the moment,” noted Smith. “We’re working on several others as well. We have often seen in our early stage testing that many different kinds of microalgae have different positive effects on plant agriculture, so we’re bringing many of them along,” he said.

Unlock the secrets in the soil diversity

Natural Resources Conservation Service (NRCS) Soil Health Campaign

Smith said these algae are among the most common components in healthy soil. “A lot of what we’re doing is actually restoring what is already present in the soil. A lot of the scientists we work with think this is a critical component of the whole plant ecosystem below the soil line.”

Similarly, many university researchers are taking a closer look at algae. “We have about 30 university and contract research studies in, and we are working with growers. We have been selling the product in what I would consider almost a beta launch mode for about two years. So, we probably have about that same number of grower trials—maybe even double that,” said Smith.

Having the algae in the soil not only increased yields, according to Smith, it increased crop quality and strengthened the soil. “Benefits include root mass; in fact, we saw a 20 percent root mass increase in cotton. We have also seen the plant’s ability to grow in stressed environments such as heat stress and drought stress, in some of the work UC Davis did for us. We saw a 25 to 30 percent increase in overall yield in the stressed soils in which the algae was present, as compared to the control,” Smith explained.

Could it be that algae may be the new frontier in plant health and yield? “Yes, we’re very excited about what we’re doing. I would say we are opening a field here that nobody else is really paying attention to. I think that you will be seeing more of these products come to market, hopefully helping growers get better results in a restorative and natural way,” Smith said.

Improved Huanglongbing Detection in Citrus Trees

Projects Underway for Better Huanglongbing Detection in Infected Trees

By Patrick Cavanaugh, Farm News Director

The big problem with Huanglongbing Disease (HLB), also known as citrus greening, is that an infected tree, despite having no visual symptoms, could quietly be a massive reservoir of HLB. The main vector, the Asian Citrus Psyllid (ACP), could easily pick up HLB from that tree and spread the disease throughout the orchard.

Currently, the main push to contain the possible spread of HLB is by controlling ACP. Yellow sticky traps are positioned near every commercial orchard in California, as well as near non-commercial trees in neighborhoods. Finding a psyllid on a trap triggers mandatory spray programs to help eliminate all psyllids in the area.

Neil McRoberts, associate professor of plant pathology, UC Davis

“Yes, one of the most critical questions in managing in HLB is the trees can be infected for a long time before you can visually see the ACP there,” said Neil McRoberts, an associate professor of plant pathology, University of California, Davis.

“There is a group of scientists, funded by the Citrus Research Board of California (CRB), working on different early detection methods. Those are methods where you would be able to tell the tree was infected before you could see the tree is infected,” said McRoberts.

The CRB funded field trials in Texas over the last few years that have narrowed the field of competitors to two or three techniques. The CRB will continue to fund the two leading contenders in that race to determine the leading early detection technology.

In the first technique, researchers analyzed all the microbes that live on a non-infected leaf surface and studied how that profile of microbes changes when the tree gets infected. Detecting a change in microbe profile could indicate the tree is not as healthy as it should be.

“Researchers take the microbes that live on an infected tree, extract the DNA from those microbes and run the DNA through a sequencer. The sequencer identifies which types of microbes are there,” he said.

McRoberts said sampling for microbes is easy. Researchers use an industrial-sized swab on the leaf surface. “You literally clean the leaf surface with the swab until it’s squeaky clean, put that swab in a bottle and send it to a lab. When it gets to the lab, they extract the DNA out of it and the rest of the process happens from there.

In selecting which trees should undergo microbe swabbing, McRoberts noted that the ACPs tend to attack the groves from the outer edges, inwards. “At different times of the day, the light will be on different edges of the grove depending on where the sun is and how warm it is. You can target your sampling towards the places where you’re more likely to find it, but still, finding those initial little infections is tough.”

The second method is a technique called metabolic profiling. A newly infected tree starts to produce different proteins and other chemicals in response.

Still another research strategy is analyzing things that stay in the tissue. “There’s a change in the profile of metabolites in the tree. If you run those metabolites through a mass spectrometer, the mass spectrometer will spit out a profile. You can tell the difference between a healthy profile and an infected profile,” McRoberts said.

“This is how the dogs come into the picture. Everybody knows that citrus has an odor. When the trees are infected, the profile of the chemicals and the composition of that odor change. We can’t smell it, but a very sensitive electronic detector device can sometimes pick it up. Remarkably, dogs can pick it up. We think that’s what happening with the canine detectors; they’re picking up some change in the smell of the trees.”

McRoberts said that dogs are amazingly accurate in detecting trees with HLB disease. “The best that we can tell from the trials involving dogs, the false positive rate is less than 1 in 1,000. I’m very confident with the detector dogs,” McRoberts said.

Early Rain Caused Concern for Butte County Rice Growers

Butte County Rice Growers Respond to Early Rain

By Brian German, Associate Broadcaster

The Butte County Farm Bureau has been working to protect agriculture’s interests since 1917, thanks in large part to the continued hard work of their members. With continued support, the Bureau is able to advocate for growers on important issues in the community and fund educational opportunities.

Colleen Cecil, executive director of the Bureau, observed the rice harvest looks strong for Butte County rice growers, but a weather-related issue caused a bit of a problem during harvest. “We had some wet weather and then we had a break. Then it was, ‘Hurry up and get it done before the next storm comes in,’” said Cecil.

While the weather was an issue for growers, its impact was minimal. “There was a percentage, somewhere in the teens likely, of rice that was still left out in the field after the last wet weather event [in which] we just got pounded with rain,” Cecil noted.

“Water shortages over the past couple of years had forced many rice growers in Northern California to cut back on overall production. However earlier this year, as a result of improved rainfall last winter, growers went back to planting a more average level of rice. Those fields that had been taken out of production had a good amount of rest, and are now producing nicely once again.”

Though not uncommon, growers may have adjusted their harvest schedule in response to the early winter rain. “While it does happen on occasion, it is not ideal for farmers to harvest rice after wet weather all the time. It goes more slowly, it becomes a little messier, and it requires a transition from tires to tracks on their harvesting equipment. Again, it slows it down,” Cecil said.

“In 2013, the average rice grower in Butte County was producing just under 90 sacks per acre, with each sack weighing the [approximately] 100 pounds. Butte County has close to 88 thousand bearing acres of rice. While the local industry remains strong, early rainy weather can put a dent in production.”

Cecil explained, “It wasn’t that they couldn’t get [the rice] out, it was that the crop wasn’t ready to come out. There was still a tremendous amount of moisture in it and it wasn’t at the right percentage of moisture to take out of the field, so they had to wait.”

Last year’s crop report shows that Butte County’s five most valuable crops were walnuts, almonds, rice, prunes and peaches. The area’s walnut crop alone was valued at just under $241 million dollars. Cecil said this year’s harvest, “the almonds came off without a hitch. The walnuts got tagged at the end with the wet weather, but I don’t think it slowed everybody down,” Cecil said.

Water Diversion Plan for Fish, Part 2

Grober: It Won’t Help to Vilify People

Part 2 of 2-part Series

By Patrick Cavanaugh, Farm News Director

California Ag Today conducted an extensive interview with Les Grober, assistant deputy director, State Water Resources Control Board (SWRCB, Water Board) Division of Water Rights. We published Part 1, “Water Board’s Point of View on Increasing San Joaquin River Flows,” on November 28, 2016.

http://yn2.000.myftpupload.com/increasing-san-joaquin-river-flows/

Grober explained the Water Board’s water diversion plan to adjust the flow objectives on the San Joaquin River to protect fish and wildlife. The plan, specifically, is to divert 40 percent of water flows from the Stanislaus, Tuolumne and Merced Rivers that flow into the lower San Joaquin River.

California Ag Today: We asked Mr. Grober to explain how the Federal Water users on the Westside of Fresno and Kings Counties were granted a mere 5 percent allocation this year, and why many did not receive their full 5 percent.

Grober: The 5 percent allocation is due to the junior water rights of those growers and to the interconnections of so many things — priority of right, hydrologic conditions, and minimal protections or fish and wildlife. Anyone who thinks it’s all due to fish is simplifying a very complex situation.

California Ag Today: Regarding the water hearings that are scheduled over the next few months, is the Water Board trying to give information to farmers and others would be affected by the decreased water should the Water Board’s proposal go through?

Grober: The ultimate goal is to make people even more prepared to provide comments to the Board at the scheduled hearings. It’s part of a public process where, if we did not get our economic figures right, we want [accurate] information from the stakeholder to make it right.

We thought we did a good job in an economic analysis on how we thought the proposed taking of 40 percent water would affect the communities and farmers. We clearly heard from many people who thought we did not do a good job, and my response is: Good, show us why, make a proposal and take it to the Water Board hearings, and then we can adjust it.

California Ag today: The Water Board has a 3,100-page report all about saving the salmon.

Grober: The reason we have a big report is because we are making a proposal and we’ve shown our work. Although it is work for people to look at it and review it, we have tried to make it easy so that people can see if we have made mistakes, if there are things that are left out or if we have made an incorrect assumption. That’s why we’ve shared it with everybody and here’s your opportunity for setting us straight.

It won’t help to vilify different people who are making good use of the water or to vilify or disparage the implementation of our laws and what we are required to do. We have a great process I think, as hard as it is, a public process where we can work these things out in the open, just to use it and deal with each other professionally.

-Les Grober, assistant deputy director, State Water Resources Control Board (SWRCB, Water Board) Division of Water Rights

California Ag Today: We are sure you are getting a lot of information from farmers and city leaders about this not being a good use of the water.

Grober: These problems are not so simple that they could be reduced to a sound bite. I think we would have solved the salmon problems by now, but because we are in the drought situation, we are dealing with a precious resource, which is water. Everybody wants the water but there’s not enough to do all the things we would like to do with it.

California Ag Today: But there are many people in California who feel that more water for fish instead of farmers is reprehensible.

Citrus Tree devastated by drought.

Grober: It won’t help to vilify different people who are making good use of the water or to vilify or disparage the implementation of our laws and what we are required to do. We have a great process I think, as hard as it is, a public process where we can work these things out in the open, just to use it and deal with each other professionally.

California Ag Today: But we’ve heard from experts that have been studying this, that the increased flows have not really helped these species. Do you have proof that they have?

Grober: It’s hard to show proof one way or the other because recently we have not increased flows to see what effect it would have. That seems to be a notion that is out there, that we have somehow done something to increase flows in recent years, and that’s simply not the case.

If anything, flows have gone down. And in the recent drought years, as I said, even the minimal flows that were required were adjusted downward. You would have to show me that evidence that flows have gone up and there has been no response to those higher flows. I do not believe that there is any.

California Ag Today: So, the Water Board wants 40 percent of unimpaired flows?

Grober: When we say the requirement is 30 percent to 50 percent of unimpaired flows, it is 30 percent to 50 percent of that amount, which means just the opposite. It means that 50 to 70 percent of [flows] for February through June would be available for consumptive use.

That is frequently misunderstood and turned around. That is still from February through June, so it means more than 50 to 70 percent since other times of the year this water is available for consumptive use.

California Ag Today: Is the Water Board looking at the fact that if the water is needed for the species, it is going to force these growers to use more groundwater? That is a direction in which we do not want to go, especially in a region that has not yet had critical overdrafts. How does the Water Board look at that domino effect forced on these growers in order to survive, stay in business and produce the food in this major Ag production region?

Grober: Implementing that 30 to 50 percent of unimpaired flows would mean less surface water available for diversion. So our analysis of the potential environmental effects and overall effects of the program, based on recent drought information and other information, shows we would see increased groundwater pumping.

California Ag Today: Is the increased pumping weighted at all in the proposal, because overdraft groundwater pumping is not sustainable?

Grober: By our analysis, the area is already in overdraft.

California Ag Today: What? Why would there be overdraft pumping in an area that has great irrigation districts such as Modesto and Oakdale Irrigation Districts delivering surface water? We did not think growers in those districts would be overdrafting.

Grober: Sure. Within those irrigation districts themselves, they are not overdrafting. That’s why the analysis we do goes into that level of detail. The irrigation districts that already have a source of surface water actually apply much more water than they need just for the crop, so they are recharging groundwater within those districts, and even with this proposal, would continue to recharge groundwater. It is all those areas outside of those districts that don’t have access to surface water that are pumping groundwater.

California Ag Today: There is a lot more pumping of groundwater on the east side near the foothills.

Grober: Based on the information that we have, the total area — not just the districts that have access to surface water — but the total area, is already overdrafting groundwater. And there are many areas on the east side of these districts now, up into areas that were previously not irrigated, converting now to orchard crops. So with the information we have, there are large areas of production using water from the basin. The entire area is to some extent pumping more groundwater than there is recharge.

California Ag Today: We’ve been concern about this.

Grober: That’s why the Sustainable Groundwater Management Act (SGMA) is going to be good, because the local areas are going to have to get on top of that information and on top of the management.

Water Board’s Point of View on Increasing San Joaquin River Flows, Part 1

Les Grober Explains Increasing San Joaquin River Flows

This is part 1 of a 2-part series.

By Patrick Cavanaugh, Farm News Director

California Ag Today conducted an extensive interview with Les Grober, assistant deputy director, State Water Resources Control Board (SWRCB, Water Board) Division of Water Rights, regarding the Water Board’s proposal to adjust the flow objectives on the San Joaquin River to protect fish and wildlife. The plan, specifically, is to divert 40 percent of water flows from the Stanislaus, Tuolumne and Merced Rivers that flow into the lower San Joaquin River.

Hearing on the Potential Changes to the Water Quality Control Plan for the San Francisco Bay-Sacramento/San Joaquin Delta Estuary: San Joaquin River Flows and Southern Delta Water Quality and on the Adequacy of the Supporting Recirculated Draft Substitute Environmental Document.

Hearing begins at 9:00 a.m. on the following dates:

November 29, 2016 Joe Serna Jr. CalEPA Headquarters Building, Byron Sher Auditorium, 1001 I Street, 2nd Floor, Sacramento, CA 95814

December 16, 2016 Stockton Memorial Civic Auditorium, Main Hall, 525 N. Center Street, Stockton, CA 95202

January 3, 2017 Joe Serna Jr. CalEPA Headquarters Building, Coastal Hearing Room, 1001 I Street, 2nd Floor, Sacramento, CA 95814

California Ag Today: At a recent public workshop in Sacramento, Les Grober, you cited some statistics that show the Water Board really has not done a lot—or much of anything particularly—in the San Joaquin River in terms of helping salmon. Is this accurate?

Grober: Yes. I did not discuss specifically the flow benefits or the fish benefits, but I did explain there are times between February and June when flows are critical for salmon. During the months of March and April, especially, less than 10 percent of the water flows than would be there normally if you were not storing it or diverting it.

Water Board proposes water diversions for fish from three San Joaquin River tributaries: Stanislaus, Tuolumne, and Merced Rivers (Map Source: WorthYourFight.org)

California Ag Today: So the Water Board proposes taking 40 percent from the rivers to help the salmon?

Grober: I posed the question, “If there is a species that has adapted to 100 percent flow, how likely would it be that it could be successful with less than 10 percent of that?” If you look at the overall statistics between 1984 and 2009 for the three tributaries (Stanislaus, Tuolumne and Merced Rivers), the average flow during the February through June period was 40 percent on the Stanislaus, 21 percent on the Tuolumne, and 26 percent on the Merced.

California Ag Today: So you need water from all three tributaries to accomplish the objective?

Grober: Currently, there are flow objectives only for the San Joaquin River at Vernalis where the San Joaquin River flows into the Delta. The current objective skews the flows so they are coming from just the Stanislaus River, which has problems achieving those flows at all times because it is all coming from one location. It also does not achieve the fish protection goals because it’s all coming from the same location.

So, based on the core science, we are proposing to establish objectives on the three salmon-bearing tributaries to the San Joaquin River. This is about reasonably protecting fish and wildlife in the San Joaquin River.

California Ag Today: So the Water Board is not trying to protect the salmon at any cost, which is the mandate from the Endangered Species Act?

Grober: The proposal is not establishing flows that provide absolute protection. We are establishing flows to reasonably protect species—in this case—fish and wildlife.

California Ag Today: The Water Board earlier proposed the need for 60 percent to be unimpaired flows?

Grober: The science developed over the years has shown that if you were not going to consider any other uses of water, like agriculture, drinking water or anything else, the number you would need is 60 percent of unimpaired flow.

California Ag Today: Due to agriculture pushback, the new goal is 40 percent?

Grober: That is why what we are doing now is very hard. We’re doing the balancing that says we have the science that shows the need for increased flows. We have all the information that shows how important the current uses of water are now for agriculture and municipal supply and hydropower. so how do you come up with a balance that takes into account all of that information?

California Ag Today: We have been following closely the extraordinarily increased flows through the Delta and to the Pacific Ocean, which seemed to be No. 1, a total waste of freshwater, and No. 2, at least a few acre-feet could have been pumped into the San Luis Reservoir for cities and farmers.

Grober: It would be interesting to see the numbers that you are citing because, during this recent drought, in particular, there have been greatly reduced flows throughout the system—not in any way—by any stretch—increased flows. In fact, the Water Board approved emergency change petitions not to increase flows, but to do just the opposite.

In general, they have relaxed or shifted downward required flows so there would be more water available to be smartly used for multiple purposes, not just for fish and wildlife, but also to get more water for public interest uses.

California Ag Today: We know that flood control pulse flows are difficult to capture, but it seems that some of that great volume of water could be pumped southward.

Grober: Many times, people will fail to notice or acknowledge that during periods of high rainfall and high flow, a lot of water goes out because it cannot be captured. So very large quantities of water go out because of flood flows and high flows.

This is not to say that there are no constraints, at times, on what can be diverted or exported to protect fish and wildlife due to objectives, the State Boards, the Water Quality Control Plan, or biological opinions. But much of that water that people look at and say, ‘Why is that all going out?’ — a lot of that is flood flows that cannot be captured. So it ends up looking like a very big number, but it is not a number that can be captured because, as you can imagine during wet years and high flow times, it is almost too much. People can’t capture it.

California Ag Today: So there is not even an effort to export that water to those who need it — farmers and communities?

Grober: Like I said, there have been constraints on export pumping. But those constraints are intended to provide some protections for fish and wildlife, while at the same time they are opportunities for getting water for other uses. So I see a lot of overstatements.

California Ag Today: Again, when there are pulse flows, why can’t we collect them and exported them? Why can’t we just turn up the pumps to capture some of the extra water moving through the Delta to export it to farms and cities?

Grober: There are constraints on what are called reverse flows in Old and Middle Rivers (OMR), which is a critical area of Smelt risk. This is part of the biological opinions intended to protect smelt and salmon at critical times that happen to coincide occasionally with higher flow events.

That is one of those times when it’s kind of striking a balance as well. The flows are still not optimal for the protection of the species, but certainly, from the water supply perspective, they are not seen as optimal for the water supply. That makes all of this so very hard. How do you strike that balance?

California Ag Today: You talk about striking a balance. It seems that the environmental side gets nearly 100 percent of what they need and Ag gets nearly zero.

Grober: Where is Ag getting zero?

California A Today: There are Federal Districts on Fresno County’s Westside that for several years have received zero water allocation. This past season, they were promised 5 percent, but they were not able to get the entire amount.

Grober: If I may, it is clear that you have a certain view on this.

California Ag Today: Absolutely. It just does not seem that agriculture has a seat at the table.

We’ll continue Part Two of this series tomorrow. We’ll discuss, among other things, that if the proposal goes through, farmers would be forced to use more groundwater.

Almond Alliance Advances Almond Issues

Alliance Advocates for Almond Industry

By Patrick Cavanaugh, Farm News Director

The Almond Board of California does many great things for the California almond industry, most notably marketing annually about two billion pounds of almonds—both domestically and internationally. But there is one thing the Almond Board cannot do, and that is lobby on behalf of this big industry.

Kelly Covello, president of the Almond Alliance

Enter the Almond Alliance of California (AAC) on August 1, 2016. Formerly known as the Almond Hullers and Processors Association (AHPA) and established in 1980, this renamed and revitalized trade organization is the only trade association fully dedicated to advocating for and protecting members’ investment in the almond industry. The AAC will represent and serve growers, hullers/shellers, handlers, processors and allied industry partners.

Kelly Covello, president of the Almond Alliance, said, “Over the last year, we’ve done some strategic planning with the Almond Board so that we can complement one another’s activities. The Almond Board cannot lobby or advocate, and the trade association—the Almond Alliance—can.” Nevertheless, Covello said, “the industry has invested in the Almond Board through their assessment and has great resources available in terms of expertise, data [and] research that we can use to support our policy positions.”

For nearly 100 years, the almond industry has been active in California without a dedicated political voice. “The trade association has always been able to advocate on issues when necessary. The industry has grown; we’re over a million acres now. With the increase in acreage, the number of issues, the visibility and the scrutiny of our industry has dramatically increased,” Covello said.

Ms. Covello currently serves on the Board of Directors for the Agricultural Council of California and serves on two Almond Board of California (ABC) committees: the Almond Quality & Food Safety Committee and the Technical and Regulatory Affairs Committee.
