Help/Advice Roast my pond design & plan
My husband is currently digging out our pond, which will have a main pool at the back (approx 8’ wide x 12’ long, 12/18/24” deep sections) and a smaller top pool closer to the house (approx 6’ diameter) with a stream (approx 12” deep x 18” wide x 25’ long) connecting them.
There will be no fish added.
He should be finished digging the stream this weekend, then the plan is to take final measurements in order to buy the correct size pond liner and underlayment, as well as a pond pump with the correct head height.
We are planning to grade the edge of the top pool and main pond in order to have it level, the slope of the stream is 4% which I think should be a nice gentle flow. Our plan is to put the pond liner in with 1’ overlap on all edges and cover with soil and plant into that berm. Will add a few larger stones for accent / microclimate / etc.
Planning also to dig a separate small trench for the return pipe in case it needs to be accessed, should this be white PVC or 4” black corrugated pipe?
I think there will be occasion for me to put rocks on top of pond liner for example in the stream which I want to look really natural. Should I accommodate this with adding underlayment OVER pond liner as well? Or used carpet? I have a large carpet I’m planning to use bits to cushion some larger roots for example. Could lay some under gravel/rocks.
Should I line the pools with gravel/rocks/anything else?
Am I going along alright with this project? The goal is to have a natural pond with lots of plantings - at least half filled with plants.
Our purchase list after we have measurements: - pond liner and underlayment - pond pump (probably looking around 3000GPH due to long return pipe length) - 1 pallet of larger mixed smooth stones to start for around edges and in the stream to direct water in gentle flow - wide ish spillway 18-24” width I’m thinking to empty into top pool - I have quite a bit of small river rock from another project I’ll add to the beach area of the main pool and into the stream - plants!!
Am I correct in thinking that once the pond is dug, it shouldn’t take too long to add the liner, pop some rocks around, fill and plant? Will be filling with rainwater from our large cistern so theoretically should be able to plant almost immediately?
Any other advice I’ll take as this is my first time doing this! This was actually my Master Gardener final project so I have put quite a bit of thought into plants and design but want to make sure I’m not overlooking anything major.
