Inverted Spillway on a Lake

11/26/2022 7:58 AM

An inverted spillway on a lake takes water from below the surface and removes sediment from the bottom.This allows fresh water to replace the stagnant bottom water and results in a cleaner lake.

Imagine an open spill way pipe with another larger capped pipe surrounding it but the open end mounted slightly above the bottom of the lake.

The diemensions of each could be determined according to the expected demands,plus a Murphy law addition.

I wonder why this is not implemented more widely.This could also prevent surface freezing from obstructing drainage,and the resultant ice dams.

I think you must be referring to pond aeration to prevent water stagnation...

One year update...
