Thanks for the input. We've dropped the pond 4 feet because we are putting in a cabin and 90% of it (the cabin) will be suspended over water. They should be pouring the pilings/foundation in the next few weeks if the weather would warm up. Since the water has dropped we have two arms (8 feet wide, 40 yards long, 3-4 feet deep) that are now completely dry. I plan on fencing off one of the arms since the lake is down and growing out the HSB there. I'm going to do 50 per acre and keep a close eye on them. If I get too many lbs/acre I'll harvest accordingly. Here are a few pictures of the pond (Mike Otto helped us design it). We've dug out the arm by the little pond another 25 yards in length last week. That is the arm which I plan to fence off.
