For some reason or other it seems if yuou have curretnt flowing and a
fish can get into it, it will follow it. I had problems myself with
some going out through the spillway, and yet others under the
spillway in another barrel continualy jumping up as if they were
salmon doing the run up stream thing. Netting works, but not as good
as a plastic barrier / guard does, plus plastic is easier to keep
clean.Use polycarbonate, not plexiglass or its apt to craze and crack
in sunlight, plus its not as flexible as polycarbonate is.......Lexan
is a polycarbonate plastic.........Lucite, Plexiglass is not.
