California has only 20 million acre feet of reservoir capacity, which is currently filled to 125% of typical levels. The last thing that state needs is another 75 million acre feet of water.
- dv_dt 9y agoA pipe delivering enough to refill groundwater levels in CA would still be very useful though...

- dragonwriter 9y agoCalifornia has very roughly a billion acre-feet of groundwater capacity[0], and it is so severely depleted from being pumped out to cope with surface-water shortfalls over the years that the Central Valley is sinking (and eroding groundwater capacity in the process.) California doesn't need 75 million more acre-feet of surface water, but it could probably benefit from multiples of that being pumped back into the ground.
