Natural 'pond' development help
At my work (a lovely woodland holiday club) we have a small stream running over the land to a bigger stream, and halfway through there is a place that looks like a natural pond where the water builds up before it carries on.
We'd love to develop it into an actual pond, as we have some very eager ducks and it's in a patch of land we want to turn into a wildlife area.
Is it possible to just dig it a bit larger and deeper and it'll be a pond? Or is it necessary to completely drain it and line it?
Many thanks in advance!
