We did 'shroom stumps along the edge of the creek channel rather than burning them. Pond builder tapped them in with the trackhoe. Great cover. Note: It's NOT a swimming pond! I still have some small floating sticks and logs that pop up know and then since the pond has filled. Kind of irritating, I'm just glad they're not stumps. My pond experience on waiting until "later": I installed wood duck boxes "later". Bad idea! Driving 4x4 posts into a pond bottom in ~6" of water then trying to attach the boxes all from a jon boat was painful!
Here's one for the 'shroom stumps!
