Would a winter drawdown help with algae problems? Our pond is 1-1/2 acres and 8 - 12 feet deep and I was thinking of dropping the level 2 - 3 feet first of all to be able to drag the sand back up on the beach but I have also heard that some algae problems can be helped by a winter drawdown. We have a problem (not too severe) with a blue-green algae that forms on the bottom of the shallower parts of the pond. Any recommendations on this? How many months should I leave the level low? The pond is stocked with bass, bluegill, & catfish.
