hey there say, ed... thanks for sharing, along with DMT's share...
say, so now, can you share any info on what this means, as to these
movements of the earth?
is it something that can cause fault lines, to trigger
earthquakes in any more of a way, than they
'may be set for' now?
thanks, as i was wondering about this, as, calif
has this earthquake activity going on behind the scenes,
daily, as it is, for years now... is this a 'getting worse' type kick-in... ?
that drought will allow?

How much water would be in those lakes if human use were eliminated? Would there still be a drought?

I was driving back from Tuolumne Meadows today and saw a very low Lake Don Pedro, I thought it might have been the lowest I've seen it since moving back to California... I usually get a look on the trip to the Valley or Tuolumne Meadows.
Downloading the data
http://cdec.water.ca.gov/cgi-progs/queryMonthly?DNP&d=23-Aug-2014+21:45&span=2years
and a bit more work I confirmed that it is the lowest since 1995, the year I returned...
though you can see there have been other low years recently, just not as low as this year. And the recent draught seems to have lasted a but longer.

240 Gt is a lot of water...
I had wondered as the amount of energy to pump that much water to the surface...
in California, well depths in San Joaquin county average something like 3500 feet (1067 m) where as in Sacramento they're more like 500 feet (152 m).
The science article shows the "mass deficit" map:
(A) Loading estimate for the western USA in March 2014. Redder areas indicate negative loading (mass deficit relative to the 2003-2012 mean), bluer areas indicate positive loading (mass surplus), and white areas are unchanged. (B) Vertical displacements corresponding to loading model in left panel, at the locations of the GPS stations used in this analysis (compare to actual displacements in rightmost panel of Fig. 2).
So calculating the total energy required to pump the water:
E = mgh/e
where m is the mass of the water, and h is the height it is pumped, take this to be 1067 m... g is the acceleration of gravity = 9.8m/s^2, and e is the efficiency of the pumps.
I took e = 0.1 which is a 10% efficiency (30% efficiency to generate electricity, and 30% efficiency to pump)
7.22E19 Joules
which is 23,000 GWh of electricity
it's quite a bit of energy.
So we should notice this in the California energy consumption... I can get that for yearly values:
http://energyalmanac.ca.gov/electricity/electric_generation_capacity.html
If I take the annual Lake Don Pedro capacity and plot it on the same plot as the natural gas energy use (which is where most of the electricity is generated) we find an amazing anti-correlation:
that is, when Lake Don Pedro capacity is down, California energy use is up, by about 20,000 GWh.
so that's not a bad estimate...
This isn't so evident before 2003, that was the year that the EPA started regulating diesel pumps in the central valley... I wonder if there was a switch to electric pumping...
The article in Science should have "seen" the 2008 pumping if it had been at the same level as the recent pumping...
but it doesn't seem to be there at the same magnitude...

California Water Infrastructure on Verge of Historic Collapse
By Jonathan Benson, www.naturalnews.com | September 1, 2014
By Jonathan Benson, contributing writer to Natural News
Water is increasingly hard to come by in drought-stricken California, where many farmers are struggling to get enough water just to pay the bills. But the situation in the Golden State is far worse than many people realize, according to new reports, as underground aquifers that take decades to recharge are being sucked dry, and water infrastructure that has long sustained the agricultural growing regions of the state continue their collapse.
Writing for The Washington Post (WP), journalist Joby Warrick draws attention to what many scientists say is an unprecedented collapse of California’s vast water infrastructure, which is marked by an elaborate system of canals, reservoirs and wells that transfer water from the mountains and other areas to the Central Valley. Altogether, the state contains some 27 million acres of cropland. This system is now failing, say experts, and the consequences will more than likely be unparalleled in California’s history.
According to the report, many of California’s underground aquifers, which are typically drawn upon as a last resort when all else fails, are now the go-to for watering food crops throughout the state. In some areas, these aquifers have dropped by as much as 100 feet, an unprecedented decline that, even if the drought suddenly ended, would likely take several decades or longer to fully recharge.
“A well-managed basin is used like a reserve bank account,” stated Richard A#@&%e, a professor emeritus of resource economics from the University of California at Davis, to WP. A#@&%e co-authored a study published back in July that estimates a 5.1 million acre-feet loss of water this year from California’s underground reserves, a volume the size of Lake Shasta, the state’s largest water reservoir.
“We’re acting like the super rich who have so much money they don’t need to balance their checkbook.”
Thousands of California Farmers Could Lose Their Land if Water Runs Out
But many farmers have no choice. They either have to pull the water now to save their crops or face potential bankruptcy and the loss of their farms. Because of the immense scarcity of water this year — some 60 percent of California is now recorded as being at the highest level of drought, dubbed “exceptional” — many farmers didn’t even receive a share from the infrastructure.
One such farmer is Joe Carrancho, who grows rice in Willows, California. The 71-year-old lost 25 percent of his usual water allotment this year — and he is considered lucky, since some farmers received no water at all — and is now struggling to make payroll. He is also having to make payments on a $500,000 rice harvester that, despite the water losses, still costs the same every month.
“I have 25 percent less production, but no one is giving me a 25 percent break in my bills,” he told WP.
Lawmakers Propose Drastic Water Restrictions to Avoid Collapse
Agriculture is by far the largest water consumer in the state, representing more than 40 percent of California’s water usage. Even with about 35 million residents, California’s urban areas only account for about 9 percent of overall water usage, which is minimal in the larger scheme of things.
But state lawmakers are moving to impose tighter water restrictions, including a $7.5 million bond measure that, if passed this fall, would expand the state’s reservoir system and improve water recycling and other conservation efforts.
“We’ve reached a tipping point where the surface water is no longer enough, yet there are increasing demands from both agriculture and the environment,” added groundwater management expert and hydrologist Graham Fogg to WP.
For some reason Richard A#@&%e's name triggers control charters instead of his last name: H O W I T T

So, according to that last quote, I'm supposed to have sympathy for a rice farmer in CA? Pretty sure that plant wasn't really meant for that type of climate. Surely there are better uses of water than trying to grow a water intensive grain in a dry Mediterranean climate?

I'm skeptical of that article too. Ag accounts for more than 40% of total water usage as the article states. I think it's more like 80%.
Yeah, rice farmers in CA going out of buisness? 'Bout time.

Producing rice in California seems like a 5.13X type of business.
On the bright side, if the economy tanks hard enough, he can afford to pay 3rd world labor rates to formerly too-good-for-manual-labor unemployed white collar workers, decide every day how many of those begging for work to take, and get rid of his expensive machine payments.
Now that's back to basics, sensible management.

The farming lobby has a story about water use that they regularly peddle, which is that the largest use of water in Ca is not farming.
They describe it in various ways, but it amounts to "the environment", which they mean by allowing water to flow down a river.
They have the clear agenda of grabbing that "wasted water".
So, they do use 40% of ALL THE WATER THAT FALLS IN THE STATE. but 80% of the water collected in the various dams and water projects.
This is a video of a recent water forum that I attended, with a bunch of experts from different sources, including a farming advocate:

"Since 2011, the amount of water removed from these river basins each year added up to 4 trillion gallons.
That’s 'an amount far greater than California’s 38 million residents use in cities and homes annually,' NASA noted."

and no relief predicted.
some months back, the conditions predicted an "El Nino" condition was a likely probability, meaning a heavy rainfall year coming up was a strong possibility.
However, that has changed, and now it is only an ordinary probability, making it much less likely, and more likely for an average, or below average year again.

Looks like in typical politician fashion, the "toss big money at a problem" attempt at a solution has arrived at last.....http://news.yahoo.com/californians-favor-7-5-billion-water-bond-fight-214343680.html
Dingus, you voting for this or against it? BTW, the comments of that story are particularly engaging.
Snippet of story:
"SACRAMENTO Calif. (Reuters) - Most Californians favor a ballot initiative authorizing spending $7.5 billion on projects to shore up the drought-parched state's water supply, including a new reservoir and underground storage projects, a poll shows." See, you can have a $6 billion dollar high speed electric bullet train running through calif. ya'all voted on, AND water. ...Wait...did you say $30 billion train now?...not high speed?...Diesel?.....Only a small part of Calif, and the farmlands at that?.... WTF?
I wonder what kind of mileage you folks could get with that kind of money if you simply offered to buy up some of the farmers water rights?

I'm getting wind that groundwater basin management plans have been dictated from above, and we will likely see monitoring/metering and reporting in the not too distant future (nothing about restrictions/limitations yet, but surely that is a decade down the road, maybe less).
We are looking at using groundwater for irrigation on my work campus (we use potable at the moment and spend probably a quarter million a year just watering landscaping). Fortunately, or unfortunately depending on the person, our groundwater table is high and rising (in an IE desert locale to boot). In our early stages of this project we are hearing that the EMWDistrict will want extraction data off our planned new wells to satisfy their basin plan reqs.
