Pond hole keeps filling up with water
I've started digging a pond on heavy clay soil and have now dug down to 2 foot at the deepest. The problem is it keeps filling up with water which then won't drain away. I emptied 20 litres last night and 20 more today.
We've had heavy rain but obviously the water's much deeper than that. It''s on a slop of about half a foot - do you think the water is coming down from the surrounding area?
My Mum thinks I've reached the water table but it didn't fill with water as I was digging.
I'm worried about how I'm going to line it when it's so wet and whether the water will then build up under the liner? Any advice appreciated please.
