Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Cow manure is ruining my pond!

You're going to have to try to work with your neighbor if you hope to keep the cows away from the pond.

If the "downhill" (dam) side is on your neighbor's half, a gravity feed water line could be installed to water the cows downhill from the pond, with it fenced off to keep them out. (We have 1" black plastic waterlines buried from filters suspended inside our 2 ponds to freezeout hydrants located below the dams which we use to water our cattle in the Summer.)

Your help with installation (parts, labor, and/or $) may well be needed since your neighbor may not think there is a problem.
