Here’s Frank’s Comment. There is a lot of debris on the bottom of the lakes. What problem does this cause in my opinion? I believe it decreases property value (unsightly), might make it unsafe for skiers who fall (mainly trick and wake board skiers) and has an adverse effect on slalom skiing (shallow water = more speed). Additionally, backwash has become a problem with some of the lakes. There are a number of causes for backwash–irregular bottom & shorelines and reflections from man-made construction, such as docks and retaining walls. Frank Harwood : -)
