Two years ago, the amount of water in the massive Diamond Valley Lake was … well, not so massive. Able to hold 810,000 acre-feet of water, an extended drought had dropped storage at the reservoir near Hemet to 299,638 acre-feet in March 2016 — and it was that high due to conservation efforts. The water level dropped so low, private fishing boats were banned for 13 months. Even after extending the marina’s long boat ramp, it ended at dirt, not water. Islands and rock piles began popping out of the lake’s surface.
