I'm finally moving forward with my second pond! Dude's supposed to grade and dig the hole tomorrow
If you don't remember, I currently have a 1000G pond, and I'm building a second 6000G pond about 10' North and 4' lower than the original. I plan to pump the new 6000G pond to a bog filter that will freefall into the original 1000G pond, then have a stream / waterfall from the 1000G to the new 6000G.
I haven't bought the liner yet (I need to make sure of the dimensions when the hole is dug), but I'm planning on buying the super thick Firewall liner. Which is probably overkill, but I have an oak tree nearby and I want to be safe in case a limb falls in to it.
This question is about the stream / waterfall.
I plan to run a piece of that Firestone liner, with river rock along the sides to make the liner into a trench. Then I'll lay in gravel and big flat rock, and cover the edges with more river rock, to make it look natural.
Do I need to put anything underneath the liner? Or is it OK to just lay it straight on the ground?
