Pond Boss Forums POND CONSTRUCTION Renovating a Pond or Lake? Pond Muck Question

Muck accumulates from anything organic going into the pond. Dust, pollen, leaves, etc., etc. It also builds up from any organics that the stream washes into the pond.

16"-18" isn't too much in that amount of time, I have seen that much build up in a few years in ponds that are surrounded by woods and have a tremendous amount of leaves enter the pond in the Fall.

Digging it deeper won't prevent the muck from building up, but it will give you a MUCH longer time before it gets shallow enough that you have to clean it out.

When I renovated my pond we dug it 21' deep in the deepest part.
