I will see what they say. The problem was the pond was dug with steep sides. They had a ride on trencher they were using to install the liner and it could not operate on the steep bank slope so their only option was to dig the trench on the flat ground outside of where the excavation took place.
I guess what should have been done was that side graded down before the liner people go there. Everything went so fast we didn't really properly prepare.
The bulk of the digging was done in two days, a couple days later the liner people showed up and then in two days we were filling it.
