I have a new 2 acre pond and have just started adding some brush piles to the perimeter. I have just been using limbs from the trees that they pushed up when digging the pond. I have placed the few that I have made so far about 8-12 feet out from the edge of the water so that the tops of the limbs are just showing. My plan is to have one of these piles every 15-30 yards around the perimeter. I still have some timber standing in the middle but know that it will die out sometime. By using hardwoods I shouldn't increase sediment should I? What diameter limbs are best? Are there any wood types other than soft woods to avoid? Any other suggestions would be appreciated.
