Beginning in 2012, chapter members have been sampling Apple Creek for macroinvertebrates at 2 sites one to two times a year. Sampling tools are dip nets and kick seines.
A diverse array of invertebrates has been recorded, especially those taxa (mayflies, caddis flies and stoneflies) sensitive to water pollutants. An assessment of macroinvertebrate diversity is used to calculate a pollution index of stream water quality . in Apple Creek. In all surveys at both sites, water quality has registered as excellent.
Macroinvertebrates in Apple Creek serve as a major food source for stocked trout and serve as indicators to fly fishermen what fly patterns can be successfully fished.
