Im not sure about how the fishing is in Dunns Creek for sure. I have never fished in the actual creek, i have fished the mouth and all the docks on the west shorline by the creek. Crescent is a bad lake when the wind is up and almost unfishable. If you stay at Georgia boys you can fish the lake if its a good day and if its windy you can just stay in the creek and not have to worry about braving the waves.
