I’ve never fished the creek that flows through the park itself. Be aware that the Amicalola River, much farther south, has a delayed harvest section that is stocked during the winter and has nothing to do with the state park. That may be a source of confusion. You’ll be within a 30 minute drive of some notable (by Georgia standards) stocked and wild trout water. The Blue Ridge WMA is nearby. Feel free to shoot me a message if you’re interested in that option and I can offer you directions to some decent water.
