Trav,
I don't have the experience that you have when it comes to fishing lower taney, having just moved to springfield three years ago it has not been untill then that I began to fish taney. In the three years I have fished the lake it has been awesome. The lake holds numbers of largemouth and several I have caught go well over 5 and I have seen some BIG fish on their beds. As for the browns eating everything, almost all species that I catch on taney seem to be healthy. Taney offers great diversity and oppertunities to catch a trophy of several species. If you want walleye go to BS, Stockton, Greers Ferry, and the same goes with any species. As far as forage fish like shad declining, it may be due to the water quality not over predation.
