This what I start with, drywall mud 5 gal. buckets. (It doesnt hurt the fish or lake if some mud is still in the buckets, most is made from recycled paper anyway) Fill the buckets about 2/3 or 3/4 up with p gravel or 3/4" clean. Then you insert your structure, mix concrete, pour in bucket till full. (these pic's coming soon.
