Should California Spend 4B Gallons of Water on Six Endangered Fish?

The headline sensationalizes a bit. It's not the 6 fish that are at issue, it's the balance between human activities and ecosystem degradation that we as a society are willing to accept. The Endangered Species Act has saved dozens of beaches and wetlands in Texas from being overrun by oil and gas development. Often a few fish or frogs were the only thing standing in their way!
- MBlume 12y ago
  Wait, how is that a useful way to think about this at all? Right now we are talking about six fish. In what way are they not at issue?
  - lr 12y ago
    I don't know, they might hold the cure to cancer... We destroy our ecosystem at our own peril. In this time of drought, this seems like a no-brainer, but I would rather spend water on fish in an actual river (where tens of millions of other creatures live) than for cattle or almonds.
  - imh 12y ago
    Thinking about these actions in aggregate, it can be about losing X gazillion gallons of water to save a species, instead of 4B for 6 fish. I think the point is that these actions add up.
  - thrownaway2424 12y ago
    Think of it as the cost of these six and all future fish of this species.

    In addition to the difficulty of measuring the cost of losing an entire species forever, as others have pointed out, the question is really do we want this to be an actual functioning river? The more sensitive species are indicators that something has been fundamental changed in the ecosystem.

  Thank you. Its not a matter of do we spend 4 Billion gallons of water to save 6 fish. The point is a deeper question about the human race's resource consumption in the larger picture of things. Another facet of this is 'flushing' as if flushing in it of itself is some natural phenomena. In reality, its also a compromise between our need for reliable water and a natural watershed. Given how much water is going into animal based agriculture in California (not Almonds like so many people like to scape goat), it will be interesting to see if there is any real change in behavior from humans. For instance, there is this big push to reduce lawn watering and car washing, both things that are wasteful in a desert - but if we eat beef at every sitting, it might be just as much water consumption. There needs to be a comprehensive breakdown of individual/household water consumption where you can put in what you do/eat/where you live etc. This should be compared to top down approaches that are more common and then there should be a campaign/effort to dessiminate statistically based information that suggests where and why you should cut down on your resource consumption. It needs to be data driven.

  Exactly. This entire argument is just absurd. Should be bulldoze San Francisco in order to save 4 spiders? There are people who would. Yet some starving kid and nobody cares.
JohnTHaller 12y ago
Doing the conversions, they want to flush 651,702,863 gallons of water per fish. That's nearly 4 billion gallons of water for 6 fish.
- anigbrowl 12y ago
  This is bullshit. We've been diverting some water flow each year to safeguard a population of what used to be thousands of spawning fish. But as the fish population has come under greater and greater pressure, the population of the fish species in question has fallen to 6, so for all practical purposes it has now gone instincts EDIT extinct (sorry) while people have been arguing over how little water it can get by with. Stop over-simplifying complex issues. It doesn't help anyone.
  - JohnTHaller 12y ago
    I looked up and did the conversions because I had no idea what a foot acre was. I thought other folks would be interested as well. I expressed no opinion on whether it was a worthwhile endeavor one way or another. I'm personally not a fan of the 1.1 trillion gallons used for almonds while they pull water off restaurant tables (yeah, that'll work), but I didn't think that had any place here either.
    - anigbrowl 12y ago

      - briandear 12y ago
        The population of this fish hasn't fallen to 6. This is about 6 instances of a particular fish, not the final 6 instances. I am interested in the outrage over wind power in California. The Condor is killed by windmills, yet the environmentalists keep demanding windmills. Environmental groups like the Sierra Club would bulldoze a city to save a endangered rat but say nothing about the danger of windmills.

- JohnTHaller 12y ago
  4 billion gallons of water to save 6 actual fish.
  - jfoutz 12y ago
    Is 4 billion a lot? that's like 1/2 a day's flow of the Mississippi. edit: Ah, it looks like water there is around $1000, per acre foot. 12,000 acre feet, so 1.2 million. 200k per fish sounds pretty steep, but it looks like there are other benefits. edit 2: looks like Nestle pays about 30 bucks per acre foot. So that's only 60k per fish.
    - MichaelGG 12y ago
      I hate when they throw numbers around without scale. I'd have the same reaction if the question was 400M gallons, or 40M. It sounds like a lot, I guess. But if it's only $60K per fish and this is some particularly great way of preserving them or rekindling an ecosystem, maybe that's a great deal. Or maybe it's off by an order is magnitude, in either direction.

  California’s water system manages over 40,000,000 acre feet (49 km3) of water per year. (Wikipedia) The fish need 12,000 acre feet so 0.03% of that. Or a 245m cube.

Did you know you can eat fish? Or you could, if Central Valley growers hadn't killed them all. Did you know that, before they were all dead, migratory fish were an important method of nutrient transport from oceans to inland ecosystems? Did you know that fishing is an industry that employs plenty of people, when the fish haven't been driven to the brink of extinction? All true facts. The typical M.O. of American business and industry is to drive a species right to the edge of extinction and then let some minor weather event finish the job. That's what's happening here.

Not that this is a simple answer politically, but every time I see an article about whether we should use water on almonds[1] or alfalfa[2] or six endangered fish, I wish we would just price water more appropriately, and let more valuable uses of water win out over less. Wouldn't solve this particular issue, but a more appropriate price for this decision would at least help focus minds on what exactly is the tradeoff. This sort of thing: http://www.nytimes.com/2014/10/15/business/economy/the-price-of-water-is-too-low.html http://www.nytimes.com/2014/10/15/business/economy/the-price...

  - sandworm 12y ago

    - briandear 12y ago
      Maybe everyone should just move out of California. Or perhaps they could all just euthanize themselves? That would save a lot of water. Certainly saving six fish is far for important.
  - tim333 12y ago
    They should mandate water supply for endangered species and then after that price water at the same price for everyone. Much of the current agriculture would become unviable and the farmers could switch to either less thirst crops, growing somewhere wetter or just get some comp and do something else. Agricultural water use would plummet. Problem solved. Apart from politics of course.
anigbrowl 12y ago
Argh. I am so sick of this PR line about the fucking fish from the farmers and conservatives. I'm very disappointed to see Wired framing the story this way. I am not a big fish lover. I don't personally care about the Delta Smelt. But it's going extinct because farmers took up so much of the freshwater supply for so long and then screamed whenever any water was diverted. You know, California also has a multi-billion dollar freshwater fish industry. The Delta Smelt is important not because it's such an amazing fish but because it's a good proxy for the viability of our salmon fisheries and others like trout. This sort of zero-sum thinking is at the root of our environmental and political problems. We're playing beggar-my-neighbor with increasingly scarce resources instead of saying 'look, we have multiple stakeholders here with a variety of economic interests, and ultimately we are all in this together.' It's very depressing >:-(

    Awesome, good to see this type of thinking is backed up. Sadly, I am for the first time starting to underestimate the value of large scale farming in California. It is becoming big business instead off a good source of food, at least at a level that goes back into Californians. This might open a can of hate, but why don't we just ban exportation of our farmed food in for example a red zone district due to water shortage, i.e. it can only feed us. I bet the water usage would drop significantly.

That will drive up the cost of the farm output enough that it won't be competitive and farmers won't need so much water.

    The golf courses are just a distraction. They use nothing compared to the farming.
    - briandear 12y ago
      Exactly. But since golf is a rich person's sport, it plays into the class warfare rhetoric so enjoyed by leftist political groups. It's imagery and grandstanding rather than rational reasoning. How about uprooting the marijuana crop? Same for almonds? How about deporting the several million illegal immigrants? Certainly they're using a lot more water than would be required to save some fish. The environmental impact of millions of additional people certainly has more impact than the golf courses. We can't say that though can we? Doesn't fit the approved politics. So instead we'll revert to rich people are bad with their pesky golf courses and showering habits.
      - rmxt 12y ago
        Instead of proactively ranting politically, why not look at what the state water board says itself? "Socio-economic measures such as lot size and income – Areas with higher incomes generally use more water than areas with low incomes. Larger landscaped residential lots that require more water are often associated with more affluent communities. Additionally, higher income households may be less sensitive to the cost of water, since it represents a smaller portion of household income." http://www.waterboards.ca.gov/waterrights/water_issues/programs/drought/conservation_reporting_info.shtml http://www.waterboards.ca.gov/waterrights/water_issues/progr... Seems to suggest the exact opposite of what you're talking about re: immigrants and golf courses. Also, no one is being silenced or hushed here, so the persecution complex seems a bit misplaced.

If it prevents 4 billion gallons of water from going towards growing alfalfa in the middle of a desert, then yes, I am entirely in favor of spending 4 billion gallons to save 6 fish.
sandworm 12y ago
How much water should California spend on golf lessons for children? Or outdoor swimming pools in which nobody every swims? I can think of much greater wastes of water than trying to save an endangered species. If nothing else it allows one river to continue being an actual river for another year. Come what may, the farmers will still be physically alive next year.
- briandear 12y ago
  A swimming pool doesn't use much water. It takes about 1 shower's worth of water to keep one filled each day.
ghshephard 12y ago
One of the ways I like to do this evaluation is calculate how much the water would cost if desalinated. @$0.50/m^3 (modern price for reverse osmosis desalinated water at scale, based on pricing from Singapore desalination costs on a 25 year committed contract of a design-build-run factory) - 4B gallons = 15 million cubic meters. So we're talking $7.5 million dollars, which, in the big scheme of things, doesn't sound like a lot of money when you are thinking about endangered fish, and, more importantly, a healthy ecosystem for the other fish that are in that environment. In fact, it sounds kind of minuscule to me. Note -to those that would argue you can't take desalinated water from the ocean, and deliver it to the appropriate places for the fish @ $0.50/m^3, you are right. But what you can do, is deliver that water to residential homes and industries on the coastal area, and offset it by diverting the water that feeds into those coastal reservoirs at the source, so everything balances out.

  Using the same metrics, it would cost about $3.70 in water to produce a lb of beef which is more than that same beef would sell for wholesale.
  - ghshephard 12y ago
    Which is one of the reasons why we don't grow beef from desalinated water.
trhway 12y ago
no, we should spend it to grow a 2M lb of almonds, a $12M at retail. $12M is the peanuts ... err... almonds we're ready to finish an ecosystem for. Our brain has long way to go in order to develop any semblance of intelligence.
michas 12y ago
I never got the hype about saving endangered species. I am for ecology when it comes to contamination - clean water, air, soil are really invaluable. But when it comes to saving species then keep in mind that 95% of all species that ever lived are already extinct (dinosaurs being most famous example). So I personally don't care whether earth has 95,000 or 94,994 spiecies of fish. But I care about water that would be wasted to save them.

Thank you. Its not a matter of do we spend 4 Billion gallons of water to save 6 fish. The point is a deeper question about the human race's resource consumption in the larger picture of things.

Given how much water is going into animal based agriculture in California (not Almonds like so many people like to scape goat), it will be interesting to see if there is any real change in behavior from humans.

One of the ways I like to do this evaluation is calculate how much the water would cost if desalinated. @$0.50/m^3 (modern price for reverse osmosis desalinated water at scale, based on pricing from Singapore desalination costs on a 25 year committed contract of a design-build-run factory) - 4B gallons = 15 million cubic meters. So we're talking $7.5 million dollars, which, in the big scheme of things, doesn't sound like a lot of money when you are thinking about endangered fish, and, more importantly, a healthy ecosystem for the other fish that are in that environment. In fact, it sounds kind of minuscule to me. Note -to those that would argue you can't take desalinated water from the ocean, and deliver it to the appropriate places for the fish @ $0.50/m^3, you are right. But what you can do, is deliver that water to residential homes and industries on the coastal area, and offset it by diverting the water that feeds into those coastal reservoirs at the source, so everything balances out.

upvoted for shutting up and multiplying. It's good to see.

Using the same metrics, it would cost about $3.70 in water to produce a lb of beef which is more than that same beef would sell for wholesale.

  Which is one of the reasons why we don't grow beef from desalinated water.

no, we should spend it to grow a 2M lb of almonds, a $12M at retail. $12M is the peanuts ... err... almonds we're ready to finish an ecosystem for. Our brain has long way to go in order to develop any semblance of intelligence.

I never got the hype about saving endangered species. I am for ecology when it comes to contamination - clean water, air, soil are really invaluable. But when it comes to saving species then keep in mind that 95% of all species that ever lived are already extinct (dinosaurs being most famous example). So I personally don't care whether earth has 95,000 or 94,994 spiecies of fish. But I care about water that would be wasted to save them.
