Try not to run your big motor through the weeds, this chops up the weeds and the fragments will quickly root themselves in areas as the current or wind pushes them about the lake. When you fish these weedlines, try your best not to cast too deep into them and foul your lure. Every time you snag these weeds and remove them from the lure, you are assisting the advancement. Remember to check your boat before and after you leave a body of water that has any undesirable organisms such as Eurasian milfoil. If you are involved with fishing clubs, inform them of the dangers of Eurasian milfoil.
Some weeds are good for the fishing and aquatic life, but too much of something can also be bad.
By putting forth this extra effort you can help save your fishing hotspots and keep them from becoming weed-choked.
