Scouts out, welcome to Cali. I live in NorCal and fish mostly up here. I am no expert but from personal experiences, most lakes will have black crappies. A boat, decent fish finder, and little effort in locating schools and you should have a nice slab dinner. Due to the unpopularity and low to no demand, DFG puts no effort in growing crappies out here. The good thing is that there is barely any other crappie fisherman on the lake, so you pretty much have the lake to yourself. Spring spawn brings out few annual minnow anglers but nothing compared to the Midwest. Good luck.
