Pond Boss Forums INTRO Questions & Observations Concerns about fish going over spillway?

Except for one rain event where one spillway was actually utilized, my ponds drain through 8" tiles whose inlets are blocked with netting and a grate to prevent any large fish from exiting. Before I put the grate on the second pond, I got to walk through the woods below the drain collecting YP and SMB, trying to get them back to the pond alive. No more.
