What’s All This About? Wayne County Department of Wayne County Department of
Environment (WCDOE) enlisted the Environment (WCDOE) enlisted the help of the Stream Team to undertake help of the Stream Team to undertake a benthic monitoring program a benthic monitoring program beginning in 2004, engaging a large beginning in 2004, engaging a large number of volunteers in annual number of volunteers in annual aquatic invertebrate sampling of the aquatic invertebrate sampling of the Southern Wayne County WatershedsSouthern Wayne County Watersheds
Why?Different species of aquatic
invertebrates are indicators of water quality:
ExamplesPoor: Sludgeworms, LeechesFair: Craneflies, DragonfliesGood: Stoneflies, Caddisflies

Frank & Poet Creek Water Quality Scores: Spring/Fall 2005
Key Findings:
•Frank & Poet Creek water quality in the Fall was Poor to Fair at CD-1 and CD-2, respectively (for both 2004 & 2005).
•Water Quality Rating increased slightlyat CD-1 (from 12.3 to 15.3); but, decreased at CD-2 (from 30.7 to 23.4) during Fall sampling in 2004 and 2005.
Key Findings:
•The poorest water quality ratings wereRecorded in the Spring of 2005 (CD-1 = 11.4;CD-2 = 16.4)
•Caddisflies were abundant during Fall,2004 sampling; but, were entirely absent During Fall, 2005 sampling at site CD-2!!
