CommentsThe perch initially grew to 12 or 14 inches and were very popular, but soon stunted out at about five inches. The lake was closed to fishing during 1987 while 1 -year-old fish-eating rainbows were being introduced. That plant was followed by a largemouth bass transplant. However, the $16,000 worth of recovery efforts may be stymied, since unauthorized northern pike showed up in 1988.
