tough to say, i guess it is always worth it bc you never know. BUT i can tell you that i live on the E. side of grand isle and i have tried it in 10-15 ft of water right under the ice but the perch bug the heck out of them. But i always give it a shot and never caught a trout or salmon. In the inland ponds....10-15ft of water is great range for salmon, but if i were you i would get out over some water (30ft-100ft) and set em up out there right under the ice...and use smallllll bait like said above or smelt bc if not its a long shot!!
