II. e. Real Time Operations/Monitoring/Reporting

This is not a major point of the Public Water Coalition’s position paper, but it illustrates my take on the whole piece.  One of their eight recommendations to improve water supply and reliability (Section II, starting page 4) is to start real time operations monitoring and reporting (II, e.  page 11).  In paraphrase, they propose installing measuring devices on water diversions larger than 5cfs in the Sacramento Delta and on tributary inflows.    These meters should talk to the Batcave, showing State Water Resources Control Board staff real-time diversions, with an alarm if those exceed the amount allowed by water right.  The cost of the meters should be billed to the diverters.  Who should pay for software, maintenance and monitoring is left unsaid, but I think we all know that they mean the state should pay for that.

This is a fucking FANTASTIC idea.  I would LOVE this.  In fact, I would love to see all the diversions in the state larger than 5 cfs on a real-time monitoring system, preferably on the internet, so that anyone who was interested could watch gauges all day.  It would be EVEN BETTER if each of those diversions were linked to a database of water rights, so that an exceedance turned colors and flashed for everyone to see.  Perhaps that is too much to hope for, but all diversions on everything that flows into the Delta and through the Delta would be a GREAT start.

Here the thing.  If the Public Water Coalition wants to see this happen, there is nothing to stop them from building it.  Any group of agencies that large has at least as much capacity to make this happen as the state does.   I am quite sure the agencies represented in the PWC have enough money to develop the software, integrate the water rights database, host the site and secure the telemetry.  The meters and installation would be very expensive, but they could start with their own diversions.  They could get four or five years into building this thing and hand it over to the state, who would be happy to run it after that1.  Once there were some momentum behind it, I suspect the State Board would find it a lot easier to require small diverters to join.

This illustrates my points about the nature of the Public Water Coalition:

1.  The Public Water Coalition doesn’t propose that they go ahead and do this, because they aren’t oriented towards taking their own action to solve the water problems of our state.  They are oriented towards responding to the Delta Vision process, presumably because their sole position paper got written to serve as comments to the Delta Vision Plan. 

2.  The point of the system they propose is to clamp down on the little guys.  They’re after the hundreds or thousands of little guys who don’t track their diversions well, who may go over their rights because no one has ever cared but the fish.  I’m strongly for that, but I’ve never seen big versus little put forth like this.

3.  They sure don’t offer to put up any money, and they suggest other people pay for the whole thing.

4. In-Delta water users, you are ON YOUR OWN. The Public Water Coalition is not protecting your interests.







1 Maybe not. We might not be able to afford to staff a statewide realtime water monitoring system. I try really really hard to keep insider talk off this blog. But I will tell you the insider talk that I hear at least as much as anything, which is that people in DWR are nearly desperate to keep their data gathering alive. They inherited a system of gauges all over the state and the support for maintaining and reading them has steadily declined. The state has ninety years of hydrologic record because people thought it was a prudent good management. It was. That’s how we know that climate change is happening.

But those programs have been cut back even as we need them more desperately than ever. I’ve heard men get choked up about losing the continuous data we’ve kept for seventy years on some gauges. I’ve heard talk about the gauging and record keeping programs going from nine full-time people in one region down to one, and workers checking gauges on their own time simply out of dedication. When your state is going broke and people are going without health care, it is really hard to ask for more money to check streamflow gauges. But it is an intensely valuable program that is being eaten away by budget cuts. Given that we can’t even keep that going, I don’t know if the state could take a big monitoring system if it were handed to them.

    The streamflow gauges part of this post caught my eye because it reminds me of the first paragraph here.

    Not enough state labor to acquire data?

    So, why don’t they solicit environmental groups to take this on? Or schools with programs and grad students who could do this? The state can’t be the only end-user of this data.

    I can’t imagine that the Sierra Club would pass on a chance to provide volunteers to monitor stream flows. Just curious…

    Hope all is well!

    Noumenon, that’s a neat reference.

    ScottB, there is are citizen groups that do monitoring for the state, mostly in water quality. I don’t know why there isn’t a more concerted effort to enlist volunteers. If I had to guess I’d say the gauges are hard to access, or on private property, or should be checked often enough to make doing it consistently real work.

  4. Well, if volunteers could only do inconsistent readings, would that data be actually useless or just not-as-good? People go geocaching for fun, could they be recruited for gauge reading? How can we spread egoboo when there is no money?

    (How can we prevent people from faking gauge readings when beliefs about water input are worth real money?)

    Real Time Monitoring? It’s being done at the Federal level by USGS, USACE and BUREC. I believe that the corps has a real-time monitoring system in the Sacto area. Don’t know if it is Line Of Sight LOS Radio or landline. USGS uses GOES satellite for field data communication. BuRec has some in the delta, I think.

    What you describe is presently being done on the Colorado River. I attended the ALERT conference last year in Palm Springs and they gave a presentation on their system see: http://www.alertsystems.org/aug/2008conf/AUGConfPresentations-pdf/session06/Managing/AlertUsersGroup-Gunderson.pdf .

    Del, that’s a cool presentation. Thanks! Seems like that stuff could get smaller and easier to deal with in the near future, but I’m sure reliability is important in this application – sucks to send folks to troubleshoot / lose data / etc.

    Clew, the way to stop people from faking data is to not make them write down the data. Think about meter readers these days. They are just transport – they carry data acquisition hardware and just query the meter so there’s no hands-on way for them to modify the data. That would probably require changing / updating a bunch of hardware. But that monitoring hardware, if it didn’t have the communication burden of the real-time monitoring systems, could probably be much simpler than the stuff in Del’s presentation.

    And if it had even a tiny bit of memory, it could be queried regularly by volunteers to acquire timely data but still checked say annually be the State to make sure no one is dorking around with the data.
