The Permaculture Project Days 11-13 (Bentonite, Pond, Spillway, Swales)
See how we applied and rototilled the bentonite into the pond bowl. Also, see swales, the spillway, and more pond progress. Incidentally, you will see me track rolling the pond to compact with the excavator. Do not do this if you can avoid it. Get a proper compactor. We used a sheepsfoot compactor, but it had a tough time getting to the top of the walls.
