I don't buy into that mindset for several reasons. One, Table Rock can be very good with a spinnerbait at certain times. Like most lakes. Hell I caught probably the biggest smallmouth I will ever see on a spinnerbait on Table Rock. But like many other lakes a blade just isn't consistent. Fall is great. Mid summer not so much. I do believe it's more of a depth issue than anything.
Another reason I don't buy into the whole fish are shy because they see a bunch of them is because they see a bunch of everything that they still hit. Look how many jerkbaits they have seen over the years. How many wiggle warts. Think about how many Ned rigs they have seen in the past few of years. They sure don't seem shy about any of those. look at how many fish on Lake Fork see a rattle trap. They are still hitting them.
But Stockton, and also Pomme de Terre and LOZ, are great for a spinnerbait. I think the problem that most have with Stockton is they try to fish it like Table Rock. It's not Table Rock. It's not anything like it. Has nothing to do with wind or multi-species, it's just a different lake. I'm not knocking Table Rock either. It's a great lake and a beautiful place. And if it fits your style of fishing it can be a very great place to spend your time. But there are other lakes that are just as good for fishing and a lot quieter with a bunch less boat traffic. But you have to fish them differently to find their secrets.
