When you say runoff, you are referring to discharge OUT of the pond, correct? If you have the desire to drain the pond and start over, then I think a problem with the overflow may be a cosmic sign with the words "begin project now" emblazoned right on it.

All kidding aside, it would seem to be a great opportunity to kill two birds with one stone.

Welcome to PondBoss. Some dirt guys will be along, directly I suspect. Hold tight.

"Forget pounds and ounces, I'm figuring displacement!"

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
