Ok guys thanks for all the input. As for as the Secchi Disk I have not taken any reading with one. We are having an algae bloom going on and am fighting a Colonial and a Blue Algae. We tried to put 3200 pounds of alum in this year in April to settle the algae to the bottom. It worked for a while but had to resort to Cultrine Plus spot spraying to kill it off. The lake is clearer this year than last. The question on the Largemouth Bass we have a 13-16 inch slot limit on those. Since implementing that rule the bass are getting bigger and look real healthy. As far as enforcement it is an honor system. There is no way you can enforce this on this lake since some days it gets fished and some days it may not. I tried once to get the guys to fill out a creel sheet for size, weight and numbers but only a few would do it.
