Survey data on Diamond Valley Lake (Hemet) shows there were at least 6,000 flatheads in the lake. Since they are suspected to have been in the lake only since 2004 or 2005, the oldest fish in the population are only 10 to 12 years old and weigh around 15 pounds.
The problem is anglers can’t use what would be the best baits for these trophy fish – small bluegill or gold fish. While bluegill and gold fish are legal bait in the Colorado River system they are verboten baits for Diamond Valley.
An alternative? Anglers can dip net live threadfin shad, silversides or sculpin from Diamond Valley as viable and legal flathead baits.
