Secretary of the Interior Ryan Zinke’s visit to Don Pedro and New Melones Reservoirs at the request of U.S. Representative Jeff Denham (R-Turlock) continues to yield results for the Valley, with Secretary Zinke issuing an internal memo Friday declaring the state’s proposed water grab an “unacceptable restriction” that reduces the Department of the Interior’s ability to deliver water and directing his agencies to propose a plan within 25 days to maximize water supply, construct new water storage, and resolve issues with the state, among other directives.
“After our tour of local reservoirs, Secretary Zinke recognizes that Sacramento’s water grab would cripple our communities, farms and water storage infrastructure,” Denham said. “Our water, our water rights, and our future depend on stopping this wasteful plan.”
Previously, the Bureau of Reclamation, within the Department of Interior, issued an official comment on the state’s proposed water grab, noting the plan “directly interfere[s] with the New Melones Project’s ability to store water” and “elevate[s] the Project’s fish and wildlife purposes over the Project’s irrigation and domestic purposes contrary to the prioritization scheme carefully established by Congress.”
The agency’s comment also specifies that siphoning off at least 40 percent of the Central Valley’s rivers during peak season would result in significant reductions in water storage at New Melones and result in diminished power generation as well as recreational opportunities. The agency recommends the Board reconsider and postpone the scheduled August 21-22 public meeting to allow for “additional due diligence and dialogue.”
Recently, Denham’s amendment to stop the state’s dangerous water grab passed the U.S. House of Representatives as part of a Department of the Interior appropriations bill, and put a major spotlight on this issue. The amendment, currently awaiting a vote in the Senate, prohibits federal agencies from participating in the state’s plan to deplete the federally owned New Melones reservoir, which provides water for the Central Valley Project and generates hydropower.
Sacramento’s plan would drain significantly more water from New Melones each year, potentially leaving it completely dry some years. This would put in jeopardy critical water supplies for Central Valley farmers and communities who rely on the water for their homes, businesses, farms, and electric power. The amendment takes this issue head-on to protect Valley water.
Denham will continue fighting to protect Central Valley water, support science-driven river management plans that revitalize our rivers without recklessly wasting water, and push major policies like the New WATER Act that will solve California’s water storage crisis and keep the Valley fertile and prosperous for generations to come.

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

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.
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.
