Pond Boss Forums POND CONSTRUCTION Building a dam Found trash during excavation

With a good well compacted and sealed pond, you don't need a watershed. New ponds in my area for domestic water use are now regulated to not have a water shed. My neighbor has a 0.2ac pond that is dugout and built with surrounding liner of good well compacted clay. All surfaces slope away where drainage moves away from the pond. Pond is around 23 yrs old. The most this pond has ever gone down is 12" even in our 'drought' summers. Annually we in toledo area average 33.5" precipitation per year and Dayton area averages 41". Both precipitations are more than enough to keep a well sealed pond full or near full year round. This is why I emphasize proper compaction of clay lifts are very important.
