If you're after flathead catfish near Mertens, Texas, your best bet is targeting the larger creeks and rivers that flow through the region. While no major reservoirs are immediately adjacent, these smaller waterways can hold some surprisingly large flatheads. The key is finding deep holes and structure, particularly around downed timber or rocky outcroppings. Live bait is the name of the game for flatheads; sunfish or small bullheads are local favorites. Summer nights are the most productive time to target them. A good starting point is to look for bridge crossings where you can access the creek. Be aware of water levels, as heavy rains can quickly change conditions. Always check local regulations for size and bag limits. Patience is key when flathead fishing – it can be a waiting game, but the reward of landing a big one is well worth it.
