The water buildup was mineral-rich to the point where it damaged crop roots if the water table rose high enough, so the farmers' remedy was to pump out the ground water and send it downriver.
Booty .... the boron & selenium problem is primarily a San Joaquin Valley problem, specifically Kesterson Reservoir historically speaking.
