What I did was grab a Thomas guide of the area you are in and go exploring.I found several of my "spots" by looking around and fishing them,soem were excellent some I never got bit.A little adventure is needed for this but overall it can produce some good results and then you too can have your secret spot.A good so cal small lake has been Laguna Niguel, good topwater in the morning and evenings and really healthy fish, check it out. But I can't tell you my secret spot for the same reason,TOO MUCH TRASH!!
