Lake Meredith always has some smallmouth. If you like walleye you can catch some tasty walleye there too!
Alan Henry is on the way up or back down the pan handle and is a good place to try and catch largemouth if you have time for a 2nd stop. Neighbor pulled an 8lb and a couple of 3-4lb largemouth out last month. Or so he told me.
We went the weekend after him and only caught a few largemouth in the 14-16” range and a single smallmouth around 10-12” or so. Got swarmed by “killer bees” too. That was fun.
Never fished specifically for smallmouth but I wish you luck and have lots of fun wherever you go!
No smalllies at Henry, way too many spots and some giant LM.... If you want to target smallmouth go to Amistad (up the devils river, or main lake points by dam, also can catch em on a drop shot on the fingers that come out near the channel by the dam), Texoma crank some rocky/pea gravel points... At OH Ivie it’s all random and you can’t really target them, I did catch one at LBJ at Camps a few weeks back.
