        Down the spine of California's Sierra Nevada mountains south of Yosemite, huge granite peaks stand shoulder to shoulder more than 13,000 feet high, with no passage through them. Only hikers can cross the rugged range for more than 200 miles.

       These tall mountains – the Southern Sierras – extending from the San Joaquin River watershed east of Fresno to the southern edge of Sequoia National Forest, epitomize California's erratic water supply. In wet years, so much water pours down the mountains that its volume would scare the daylights out of any creature without wings. In drought years,  meager streams cannot fill the reservoirs.

A Year Like No Other

      “This year, no one has water” said Mario Santoyo, assistant general manager of Friant Water Authority near Fresno, a unit of the Federal Central Valley Project that provides irrigation for 15,000 farmers in eastern San Joaquin Valley. “The public has no idea how bad this is going to be....there will be nothing,” said Santoyo glumly. Friant Dam distributes water to more than a million acres of fertile fields that lie mostly east of highway 99, from Madera to Kern County. The area produces more crops per volume than any other in the nation.
      Behind the dam, Millerton reservoir was dangerously low as of Feb. 7, and Friant's managers were scouring the state to find more water. We were on a boat on Millerton, touring the site of a proposed new dam, Temperance Flat, that could rise at the back end of the lake, more than doubling storage in the reservoir. (Because of its position in low hills, Friant Dam cannot be raised).

      Temperance Flat is one of the most controversial storage projects in California. Farmers want it; environmentalists oppose it; Federal officials have left it on the shelf for years. But this year, in the wake of California's epic drought year, the project is alive and well. Like nothing else, these months with no precipitation have driven home the awareness that California does not have enough water in storage to get through really bad dry periods.
      Friant farmers are particularly vulnerable this year, which helps explain why President Obama is coming to Fresno on Friday, along with Senators Dianne Feinstein and Barbara Boxer, who introduced drought-fighting legislation in Congress this week. The Senate bill counters a bill passed in the House by Republicans last week that would roll back the historic San Joaquin River restoration project, among other ill-considered features.
      A bit of background is needed to understand the stakes involved here and in the state at large. Nowhere do the competing forces of agriculture and ecology seem more tightly balanced than on the San Joaquin River at Friant.

Bright Dream; Original Sin

      Seventy years ago, the U.S. Bureau of Reclamation built this dam as the centerpiece of a hydraulic revolution in the San Joaquin Valley. By capturing the unpredictable waters of the San Joaquin watershed, Friant dam and its associated canals gave rise to an agricultural cornucopia, the pride of California and a major source of the nation's produce. Unfortunately, it also brought about one of the most painful chapters in California's water history, a history already full of painful chapters. The story is told in a moving account, The San Joaquin: A River Betrayed, by former McClatchy reporter Gene Rose.
The Federal Central Valley Project in Fresno created two separate rivers.
      In laying the concrete for this farming miracle, engineers completely reversed the flow of the San Joaquin River. They sent its waters moving south to Kern County instead of north to the Delta. The river that inspired John Muir disappeared within months. Salmon runs abruptly ended. Landowners along the course of the northern-bound river lost their water, among other deleterious effects.
      Today, the historic San Joaquin River disappears about 40 miles down from the dam, leaving a 60 mile stretch of nothing but dry sand. What ends up in the Delta, although called the “San Joaquin River”, is recreated every year out of mostly agricultural runoff that rotates repeatedly through the state water system. Its water comes with a bad mix of pesticides and tons of salt, including dangerous levels of selenium. Because it salts up the land, the recreated San Joaquin River threatens the survival of the agricultural marvel Friant Dam helped to inspire.

An Historic Win for the Ecology

A stretch of the once magnificent San Joaquin River, has
 been dry for 70 years. With restoration releases, it shows
a meager stream of new water. Bureau of Reclamation
      In one of the longest running legal cases of its kind, the Natural Resources Defense Council won a settlement seven years ago that forces the Friant Authority to release enough water into the old channel to restore the river and restart the salmon run. Environmentalists don't want any more water – not even flood waters – to be held behind any dam on the San Joaquin River. Besides, they claim, farmers already take up to 95 percent of the watershed's precipitation. Do they have to have the last .05 percent? Can't they let even one drop reach the ocean?
      Ronald Stork, policy director at Friends of the River, which helped win the restoration case in 2007 calls Temperance Flat a “dead beat dam.” He said there isn't enough yield from a new dam, over what is already taken, to justify its cost of about $3 billion. And, he added, that extra water will hardly make a dent in what farmers are currently pumping, leading to depletion of the aquifer, so its value in recharging ground water is limited.

The Case for Farmers

      Santoyo strongly counters such arguments. Flipping charts to show that flooding dramatically increased in the second half of the 20th century, Santoyo illustrated how much water is lost to agriculture. In 16 out of 35 years, from 1978 to 2013, Friant released water it could not store because Millerton is too small. In each of eight of those 16 years, more than 1 million acre feet were released – enough to irrigate Friant lands for about a year. Most of the flood releases went downstream into the old San Joaquin riverbed and eventually reached the Delta. But sometimes the water went everywhere.
Friant's Mario Santoyo: "I couldn't
move the water."
      In 1997 (the year that Yosemite Valley flooded), a rain-driven cascade of water came down the San Joaquin canyons that stunned Santoyo. It came so fast and in such volume (120,000 cubic feet per second) that no mere dam could hold it, certainly not Friant. It was like a football stadium full of water plunging into the reservoir every second, he said.
      Reclamation officials urgently called Santoyo: 'Can you move the water!?' they asked. “I couldn't,” he said. “There was no way I could move that much water through our canals.” The water simply flowed over the dam and down into the valley. “We needed a (bigger) reservoir to hold it back,” said Santoyo.

A Challenged Dam in an Era of Climate Change

      Environmentalists argue that a flood like the one in '97 does not occur often, and that's true. But climate change science predicts increased flooding from rain in the Southern Sierras. And Friant is not built to handle incredibly fast, big floods that happen over a few days, as they do in a “pineapple express” or “atmospheric river,” as these warm rains are called.

      Unlike other reservoirs in the central/southern Sierras, like the two million acre feet Don Pedro Lake to the north, or the one million acre feet Pine Flat reservoir to the south, Millerton holds only 500,000. It works more like a diversion basin than a reservoir, in that it channels water immediately into the Friant-Kern and Madera canals. By this means, it sends most of the water –1.8 million acre feet – that comes down the mountains onto the fields.

Who Gets the High Water?

      But if Friant clients use most of the San Joaquin River water now, why put themselves into big debt building another dam? At most, Temperance Flat would increase their yield by 150,000 to 250,000 acre feet per year – not overly impressive. (Formal predictions on actual yield have yet to be released in feasibility studies.) One answer is that farmers are eager to store flood waters for use during dry periods and Temperance Flat would give them that flexibility.
      But the flood waters are exactly what environmentalists want to use in restoring the San Joaquin River downstream.
     “We want to get back to a healthy river,” said Kathryn Phillips, director of the Sierra Club California. She said the river needs more flow than the amounts contributed by the restoration agreement with Friant. “If you want groundwater recharge along the river, if you want a balanced ecosystem, then you have to let the river flow. Temperance Flat will not help that; it will harm it.”

Will the Salmon Run?

      Water policy officials like Randy Fiorini, chair of the Delta Stewardship Council, have reached the opposite conclusion. Charged with the responsibility of striking a balance between water deliveries to humans and protection of the ecosystem, Fiorini said he thinks the reservoir at Friant Dam is too small.
      “I've always been one to believe that if the upper San Joaquin is to be successfully restored, the Fresno reservoir needs another million acre feet of storage.” Only then, he said, can the state meet its co-equal goals on the east side: to provide both irrigation water in dry years and in-stream flows for fish.
      Santoyo hopes other Californians will agree with that point of view and support a state bond in 2014 that he expects will allocate money for studies at Temperance Flat. Aside from a drought, the one thing that scares Friant people most is being hauled back into court, losing more water because the salmon don't run. And they won't run if the water isn't cold enough. Millerton is a small, often warm lake, said Santoyo.
      “We just don't have the volume of cold water we need to restore the salmon. It's a high priority for us. We have to succeed in bringing back the salmon.”


  1. Hi, Patricia. The next time you come over to stay at La Querencia, I'd love to talk with you. I wrote my Ph.D. dissertation on the North Fork Mono Tribe's land and water tenure, and I may be able to add an additional perspective to the debate surrounding the Temperance Flat dam. -- Best regards, Jared Dahl Aldern

    1. I would love to read your dissertation. My fiancé is Mono and I just had a class trip with SF State to tour the area that would be flooded by the proposed dam. Kelsey ST

  2. You need only ask one question to understand a Temperance Flat Dam. Who will pay for it? Not the farmers that will get all the benefit. Not the fish that lost everything to Friant Dam when it was built with NO down-steam releases. The US taxpayer will foot the bill and the benefits will go to private landowners known as farmers. And the cheap food the agricultural industry touts will actually cost a large bit of our taxes to pay all the subsidies that go to those socialist farmers. Friant Dam was built to end the groundwater overdraft but without groundwater regulation the farmers just planted more land and the overdraft continued. NO more DAMS without groundwater regulations that stop the overdraft. NO more DAMS without the water users paying for them. NO more DAMS without surface water regulations that require reservoirs to be responsibly managed for multiple years and not drained for short-term profit.

    1. Nice reply.
      I just wish you were comfortable enough to use your name and take ownership of your comment.
      If it helps any, I agree with what you have written, although I think the "socialist farmer" comment is inflammatory rather than helpful.
      Guaranteed you're not Mike Wade or Jason Peltier.

  4. Stop temperance flat dam. The San Joaquin river gorge has a great deal of importance in a historic and recreation sense. The hills are dotted with native American history. And the hiking trails give everyone a closer look at the beauty of the river gorge. Why can't we regulate ground water in the state, which would only effect those who abuse their privileges instead of permanently ruining more of the San Joaquin ecosystem, which will effect everyone. How can we legitimize a new dam when the existing reservoirs are already as low as they are. These reservoirs were never filled to capacity this year so a new dam will not fix these deficiencies. Stop temperance flat!
