Ezylman,
Thanks for the reply.
Yep - I'm expecting to need to seal the spring.
The guy who excavated for me thought maybe I should wait until the water level reaches the seepage point and then try to hand seal. He was thinking that trying to seal it beforehand would be tough - the water would just want to push out there or elsewhere was his thinking. Maybe I need some bentonite ???
He's an older gentlemen - about 75 - who has "been there done that". Can't say he's a pond expert but he's drilled water wells, installs cattle troughs all over hillsides, works around natural gas wells, can fix about anything made of metal with his welder, lathe etc.
Very little formal schooling but one of the smartest people I know.
Curious what other have to say about the pier holes too.
My 12 year old son is dying for this thing to fill. Hated to take the air out of his balloon when I told him it wouldn't be full this Summer. My guess is the pond holds around 500,000 gallons. The groundwater/spring flowing through the supply pipe has been running steady at about 2- 2.5 gpm. That's about 3000 gpd, or about 6 months worth. If we're lucky we won't have much seepage & evaporation and the groundwater will keep coming.....
