When the fish quit biting on lures or the rooster tail, slip on a small jig tipped with whatever worm or bug you can find around the pond and catch some bait. Get a half a dozen GSF or BG 3-6 inches long and then hook em up to a nice sized hook and float them in a fishy looking spot with a cork.
Just sit back and wait.
You just got to try it! I am assuming your californian pond is crystal clear and fairly deep?
