A limit of 5, I heard in a fishing shop in South Lake Tahoe last week. If the lake is not being planted with fish, or ridiculously off-trail, whatever fish are in it will be pretty wary and hard to catch. Not that it can't be done – I've seen 6 people get skunked at the same lake on the same day that someone else caught and released 60 fish. But he was one of those guys who can think like a fish, be in the right place, in the right light, at the right time and put the right thing in front of them. That's a 1 in a hundred fishermen.
