frogs can be fished in open water with good success when you use slow sinking plastic frogs like canyon plastics 4.5" frogs , zoom horny toads , rage tail toads , etc... you can run them in shallow flats and let them glide under and give them twitches wich will trigger strikes , run them like buzz baits across mid depth points , even buzz them slowly , causing a nice wake out in deeper water . my favorite place is to run them parallel to tules , just slow enough to cause a gentle wake with twitches and pauses thrown in to trigger bites . another is to actually pitch them up against thick bunches of tules and let the frog sink down to the bottom , sometimes i'll peg a 1/4 oz. weight to get them to swim on the fall . anyhow , just experiment with them and you will find sucess
