           | No, its lifespan was _extended_ by agricultural runoff
           | offsetting the natural drying out which would have otherwise
           | occurred after the event which formed it was corrected, but
           | it was _formed_ by a breach in an irrigation canal that

         | What a waste of water! Speaking to a local, they claimed that

           | water intensive crops in the SW deserts, and those farmers
           | are only paying on average 1/10th the price per gallon for
           | that same water as people pay for their home use. In many
           | cases the farmers are incentivized to _not_ be more water
           | efficient, because the old water rights can be use it or lose
           | it. They are essentially being paid to waste obscene amounts
           | of water.
           | 
           | Municipal use and waste get the most attention because they
           | are by far the most visible use, but most policies there are

           | sweet aquifers, but the utility is definitely mismanaged to
           | the extent that it's pretty doubtful if anyone really knows
           | how much water there is. Gold-mining interests are not far
           | away (hello arsenic?), lithium interests are probably looking
           | for an angle. I'm no geologist but maybe an endorheic basin
           | that collects the sweet stuff is good for that too. Anyone
           | think any of this water is being tested with a dismantled
           | EPA?
           | 
           | Anyway a water bill is about $40/month up to 8000 gallons, $3
           | extra per 1000g overage. About half of the base rate is
           | claimed as "upgrade surcharge". Since it's practically
           | unlimited for free, does that sound right to anyone? The
           | neighbors seem to be feral ghouls about 200 years old, they
           | definitely don't care much about any poisons or the town
           | drying up and blowing away, so they are always YOLOing a
