I fished Nimisilla on monday and saw large patches of brown dead weeds, found some green grass and picked up a few fish off it. I can remember when this lake was gin clear and weedy, what happened? I fished North Reservoir last night and noticed the lily pads east of the launch were shriveled up like they were sprayed. Why kill one of the only sources of cover in that place? Can anyone explain the process or thinking for weed control on these lakes or is this a natural occurance?
