Long as this has evolved into a bragging thread, I'll toss in my claim.
I've had days fishing on Lake Nacimiento in SoCal near San Luis Obispo, where I've caught over 100 fish.
Mostly consisting of White Bass with a scattering of Small Mouth and the occasional Bluegill just as a surprise catch.
Only place in Ca. where White Bass are to be found. There are a few places where Hybrids can be caught.
Naci can be an amazing fishery. I've sat in my boat near the dam looking up river across the lake where it 1/2 mile wide and two miles to the bend, and watched White Bass boiling from side to side all the way to the bend.
Add to that, a very healthy crappie population, Large Mouth, Spotted Bass, and plenty of channel cats and it makes it almost impossible to fish without catching something. At least in the Spring, Summer and Fall. I've even caught planted rainbows up where the river runs into the lake. On the down side, the river and a couple of the creeks that run into the lake come from an area that have several abandoned cinnabar mines up stream so Mercury is a real problem. Good fishing but not for the table.
