Pond Boss Forums INTRO Questions & Observations Hurricane pond prep?

Mister A, when a pond is dug, typically there will be a primary and a secondary overflow. The secondary overflow kicks in when the primary overflow is overwhelmed, and could be just a low spot at the end of the dam that is either riprap or well rooted grass. The water velocity is critical in an earthen emergency overflow because if it is too fast it can erode the dam and the dam could fail.

If ya'll are expecting a lot of rain, and the pond has a thermocline set up in it, ya'll might have a fish kill if the pond turns over.
