Good deal, I will look into the Alum treatment as you mentioned, thank you! I may pull the trigger on the Ice Eater fairly soon, just don't see any reason why it wouldn't work as well as the Aqua Thruster.

There is a small 3/4 acre pond just above this lake that I'd imagine was a great settling pond and filtered out silt/organic material but the dam ripped open on it 3 years ago as I'm told. I can only imagine how much silt dumped into the main lake now. I'd like to get that repaired but access is very tough; steep rock bluffs and tall mature trees surrounding this entire drainage system.
