TR21Bassin......shad hurt and somewhat help a small lake like Boggs. In the short-term some of the already larger bass can gorge on the big shad....and get BIGGER themselves....like we are seeing now. However, shad present another link in the food web.....therefore you have more competition and less food for some fish and in general fewer game species. As the BIG bass die off or are caught you are left with a stunted group of smaller bass who didn't have enough food to eat, or could not feed on the larger shad. KY Lake is not a good comparison for Boggs because of the sheer size difference...not to mention it is part of a major river system. You're right about the grass though. Monroe is really struggling also without the presence of grass. Ky Lake is also coming back because the grass is. Where do you mainly fish????
