Eric, here is what will likely happen if ALL of your vegetation disappears, your predators will clean house on most of your smaller fish this year. If you are bass heavy now then your LMB will likely be skinny and big headed next year as there will be little to no forage left for them next spring. Your 14-15" LMB will struggle to survive on 1" BG and you will should see a jump in the size of your BG. I have seen this scenario play out twice in the last 22 years and started to make LMB culling decisions based on how well the weed treatments went.
