In the Santa Clara valley. Used to be the water table was so high in a lot of places you could drill artesian wells. When orchard farms got going they pulled so much water that by the 19920's some places sunk 12 feet. The fix was irrigation systems and replenishment.
I read my great grandfathers diaries and water was a big deal in the 1880's. One spring after dry winter he had to slaughter all of his calves and the older dairy cows. Later that year his older brother shot himself in despair. Next year his sisters and younger brother went up to Oregon to live with relatives and never returned.
Water has been a big deal my whole life in California. That's unremarkable. What's new is it's becoming a big deal in a lot of places.
