I, too, scrathched my head over this number when I edited the article, for I
have collected in Sideling Hill Creek several times and it is lousy with
rainbows. I left the number unquestioned since I assumed it was referring to
native populations as opposed to introduced. The >600 population estimate is
published on page 34 of the publication cited in the AC article, "From the
Mountains to the Sea: The State of Maryland's Freshwater Streams."
