It's true the groundwater is being depleted in this region, but factoring in the opening up of sinkholes everywhere, and the increased volcanic activity lately, must really compound the issue. It makes me wonder of the stability of major geographic regions. Maybe California is starting to "fall into the ocean"? :O
MERCED COUNTY, Calif. — On Thursday Bay Area scientists announced that nearly 1200 square miles of California was sinking because people had pumped so much water out of the ground.
Scientists say in some spots right now the ground's sinking about one foot each year.
"That is a very high rate of subsidence," said USGS Hydrologist Michelle Sneed. "This is among the highest rates of subsidence ever measured out here in the San Joaquin Valley.”
Sneed showed us buckled concrete on sinking aqueducts and canals that no longer flow like they should.
One area where high speed rails planned has sunk five feet the last four years and sinking speeds up in dry years.
"If more rain fell and we could capture more of it and recharge the aquifer system," said Sneed, "then ground levels wouldn’t fall as fast as they are now."
Environmentalists say all this is dramatic evidence we're using far too much water, that it's unsustainable. They say nothing is more critical right now than fixing the way we deliver and allocate our water.
"We ought to be worried in the Bay Area because it's going to affect water policies statewide it's going to have ripple effects everywhere," said Peter Gleick, Director of Oakland-based Pacific Institute.
Gleick says with climate change it's fast becoming a crisis.
He says agriculture uses vast amounts of water so do people in Northern and Southern California and there are no laws regulating groundwater use.
Also the San Joaquin Delta ecosystem is collapsing because too much water has already been diverted.
Governor Brown says he's preparing a new water plan but so far has no details.
Gleick says before he can support the plan needs to know "how much water the governor's plan will take from the Delta or how much it's going to cost or who will pay for it."
The Governor is expected to announce his plan in three weeks.
