esshup - Very good info about pond side slopes and stability of pond basin banks. The steepest slopes that experienced good pond builders will build without having sloughing issues is 2.5:1. Most steep pond banks in my region are 3:1 slope. As the slope gets steeper than 3:1 it becomes more and more difficult to get good soil compaction of the bank sides. It makes good common sense that just digging a hole with an excavator will result in sides that are not well compacted and are very prone to sloughing. Good compaction and soil layer knitting of the pond banks helps stabilize the side slopes when inundated with water.
