Pond Boss Forums INTRO Questions & Observations Fish down the drain

After a 3 day heavy rain, I found hundreds of small bluegill (1" - 4") in the pasture area
below my pond's spillway areas. There are about
35' of flat emergency overflow areas on each side of the dam and a 12" siphon pipe which
feed into the creek below the dam. I'm guessing
that the observed fish were only about 10% of
what I didn't see. Would some type of screening
across the overflow area create more problems
that it would solve ? Any better solution to
this problem ?
