It’s hard to say what spurred “confidential mediation” over the Kern River that began last week. Could it be the relentless “Bring Back the Kern!” campaign by a group of young, Bakersfield residents? Could it be a sentence in a recent letter from the State Water Resources Control Board that said, in part, it “will schedule a hearing in the near future to address water availability with respect to the Kern River…”? Could it be both? No one involved in the mediation would say.
