The work was done, and it was done poorly. It didn't fix the seepage issue at all, and I was billed for the work. Several substantial holes were not backfilled well, though they are not leaking. Generally an unhappy camper, and wont be recommending them to anyone.
I will just have to deal with drops to 3 feet at the end of the year before it fills again. I am just glad the pond averages 9 feet or so when full. I happen to live in an area where storms part and generally we have a micro climate that makes sun lovers dance in joy and pond lovers weep. In all frustrating not to have a perfect pond, especially after passing up a contractor who was pricier but I found out later knew his stuff (decided before I came here).
Maybe the sun will shine on a dog's backside and the seeps will slow over time, but I dont have high expectations.
If the pond was dug downhill a little more and the surface was planned to be about 10 feet lower, I probably would have had no problems. The pricier contractor was suggesing this. There are springs on the backside the the dam the pump water up higher than that almost all year, though not of spectacular volumes. They also include some natural gas, so not sure if water quality would have suffered.
I am still far better off than with no pond, so I tell myself.
