How to fish in a golf course pond?

I go out at like 3:00 pm (even though i know thats a bad time) and i see fish jumping but i cant catch them. I use a pole with a reel obviously, i have a hook and a glittery green worm attached to it with a weight above it. I dont know if i should use a bobber and if my bait is no good either. I would like a fishing afficianado to help me.
