arrrgggh!!! I knew this would come up. I had the same idea, and asked several people locally what they thought of a beach created around the edges of my pond where my children and dog would go in. I wanted it because i lined my pond with clay as well , and when wet it is slick , sticky ,mushy , just a big ol mess. I had the idea of lining the shores with some type of screen , and then maybe some gravel , and top it off with washed sand.
No one told me that was a good idea. They all just said , just dump it in there and smoot it out , it will be fine....
so guess what , yea i did just that , lined it with sand only , and am filling again . Now you guys bring this up!!!!
