leaving trees/islands in new ponds vs. dozer out? - 09/23/13 03:55 PM
Hello,
Question for you here on leaving trees/islands in a small pond (< 2acres) with 10-12 ft max depth...
I have read perfect pond and other sources for HOURS and HOURS and HOURS, and it seems that general reco. is to seal and compact the (clay) bottom for all pond construction (other than using a liner).
What I don't comprehend is; by leaving some standing timber at the bottom or a few islands... Is that a potential source of leakage (through the roots if they penetrate your clay layer into a more porous soil)?
Also when leaving an island (with trees) either just above or below final water level... Should the clay pond bottom be disked into the island topsoil and compacted to prevent sandwiching layers or leaking at that point(like the process to add soil to the top of a dam)?
Or am I just overthinking this? It seems many people with embankment ponds simply create a dam and flood native ground leaving plenty of brush/timber/native topsoil that is not removed and/or compacted underneath.
Thanks for any help.
