Re "San Joaquin Valley sinking as groundwater stores are depleted" (April 7): The article was very informative, but I noticed the groundwater stored by nature in the extensive forested watersheds of the North Coast and Sierra Nevada wasn't mentioned. Much of our rain/snowpack falls for California falls on those forests which have been absorbing that water in the root-lased soil of the earth below for centuries.
That unique system is now threatened by the industrial timber harvest called clearcutting, the removal of most tree cover in 20-acre tracts to prepare for future profits from tree farms. This first line of water preservation is at once ruined, along with the homes of animals, and the magical ability of trees to store carbon as CO2. If responsible, sustainable tree harvest doesn't replace clearcutting, then corporate greed will destroy yet another California treasurer.
