For the pond I'm trying to renovate, see my other post on lime, I'd like to drill a well to add some water. Talked to a well driller today who told me that most of the wells in the area are 150 foot deep or so and put out maybe 10 GPM. Not too great. I asked if it's any use drilling deeper than that. He said that we'd probably hit salt water. I asked him "How salty?" He said, "too salty to treat".

I know that a certain amount of salinity in a pond is good. I believe that Bruce had a pond on the other end of the county that was fairly salty. How much can your common pond fish like BG, LMB, CC and maybe HSB stand?
