The El Niño rainstorm had already turned Nick Blom’s almond orchard into a quagmire. Still, he wheeled open the lid of a massive irrigation pipe. Fifteen minutes later, a gurgling belch heralded a gush of water that surged over the lip of the pipe and spread across five acres of almond trees.

 

Blom is neither crazy nor self-destructive. He’s a volunteer in an experiment run by UC Davis that could offer a partial solution to California’s perennial water shortages, and in the process, challenge some long-standing tenets of flood control and farming in the Central Valley.
