Bob; Some more thoughs.I forgot to mention some of the other benefits of having a well.With a well you have the added ability to drawn down your pond to do the many things that can only be done then. last fall I repaired my dock,I drew the pond down 5ft for that was able to refill it in 5 weeks. also I draw down every winter and refill when I want .We use our well for our extensive garding,also where the well water enters the pond we created a 5ft water fall( oxygen) very nice.As you can see I like my well even if my pond didn't leak I would have a well just for the above reasons
