I hope this is the right place to post this question...
We moved house recently and have dug a garden pond, with a view to attracting wildlife. However there is a high water table and the pond is filling up before we have even put the butyl liner down. Obviously if we just put the liner down there is a strong likelihood that it will just float up from the bottom. I was wondering whether it would be possible to deal with the problem by laying a hose pipe or similar pipe from the deepest part of the pond to a point at the other end of the garden, so that the upwelling water has somewhere to go--or will that make no difference unless we can lay the pipe sloping downwards from the deepest part of the pond? I'd be grateful for any advice!
Also, my wife and I read somewhere that it's a good idea to surround the edge of the pond with upside-down turfs, so that irises and marginal plants can be planted into them. (We want to have native plants so that invertebrates are attracted.) Has anyone tried this? Does it work? I believe that you are supposed to avoid getting too many nutrients into the water so that it doesn't attract great blooms of algae.
