If your fishing for trout you can catch them any time of the day. You just have to find the school and they’ll eat. If you want to catch bass or striper, morning and evening are always the best.
Your allowed 5 trout. Bass I’m not sure, I think it’s 5 bass 15” long. At the window where you pay the entrance fee you can ask for a paper that shows all the rules and regulations of the lake. It’s also shows the fish limits.
I could have been trout fishing at Castaic this whole time, and instead I've been getting skunked fishing for black bass and stripers. Now it's late July, so the trout fishing's not as good anymore.
