Pond Boss Forums STOCKING A NEW POND Types of fish to choose New YP/SMB Pond in MI - Plan

^^ What Bill said, plus if it's drained down and a pair of GSF or a few of them are in a wet boot print, and that gets missed with the piscicide, then when the pond fills back up there is a good chance that they will have survived and will re-populate the pond. All it takes is 2 fish that got missed and survive to re-populate the pond.

If it was my pond, I'd leave it full, spend the few $100 more for more Rotenone and nuke the whole thing. The risk of missing a few in a drained down pond is too great in my opinion.
