Pond Boss Forums INTRO Questions & Observations Keeping fish from escaping during floods?

It's not a spillway, but here's what I put on my first pond's drain inlet:


The primary consideration is that it is better to lose fish than a dam. Note above that if the water gets high enough (from lots of rain or a blocked screen), it by-passes the screen and enters the drain from the back side. This happens before the pond level rises enough for the emergency spillway to be in use.
