Pond Boss Forums POND CONSTRUCTION Renovating a Pond or Lake? Leave vs remove muck in upper portion of pond

I have been removing 2-3 feet of muck from a 60+ year old 1 acre pond for several weeks and am now at the upper end of the pond where there is a 30 foot wide bottleneck leading to a smaller upper pond area which is basically full of briars and rotting leaves.

I don't know if I should continue to remove All the sediment, or simply remove a foot or so in order to bring water into that area about 2 feet deep on average, possible by adding a dam across the bottleneck. Stated another way, is muck, sediment worthless in an upper pond that will be used more or less as a filtering pond, or is there any value in leaving it alone?



Thanks!
