That is a good point Mike. With the amount of flooding we had here in Nebraska along with such a high water table where this pond is at has caused the water level to be higher and into old weeds, etc so that may have a lot to do with it. I just find it hard to believe the fish can grow as well in dirty water not being able to see very far to attack prey but obviously have seen some big fish out of dirty water. And, who knows, maybe 12-18in is not 'dirty'.
