Anyone know a park that has palm size bluegill somewhere in Orange, CA *don't say centenial or mile square*?

I remember going there and fishing a really murky pond and catching really big Bluegill. Also I threw one of my lures into the other side of the pond and caught a really nice b. This park might be split into 2 sections where I caught the Bluegill the water was kind of dirty and where I caught the B the water was a little more clean. There was a small dock that had a red roof and the wood was red also. I know it's somewhere around the Santa Ana, Fountain Valley, Costa Mesa area If I saw it I would recognize it right away. If anyone knows what park I am talking about please help. I am desperate to find this place.
