Water Quality of Barred Owl Branch Nicholas Notaro ,Patrick Robbins, Jordyn Reese, Caroline Marr Caleb Riley
Problem Water Quality effects the animals that live in Barred Owl Branch.
Issue • How has the Stewardship of Harford Glen impacted its environment?
Research Question • To what extent has the water quality of Barred Owl Branch changed compared to prior data collection?
Hypothesis • Water quality will slightly improve because of establishment of new vegetation • Habitat will have improved from last data collection
Prior data • The Barred Owl Branch study started in 2007 and continued through 2009 • 2007 Northern White Pines were clear cut • Stream was slowly increasing health from 2007 to 2009
Data Collection Tools • Vernier Lab-quest • Kick seine • Tally Sheets • Ice cube trays • GPS • Chemical Kit
Chemical Tests • Phosphates • Temperature • pH
pH Data 2011 pH Level GPS Points
pH Averages pH determines how acidic or base a substance is • 2008: 6.5 • 2009: 7.31 • 2011: 7.19 Over the three year period the results have stayed in the neutral range
Temperature In Celsius GPS Points
Temperature Averages Temperature affects the dissolved oxygen the stream can hold • 2008: 25.00°C • 2009: 16.45°C • 2011: 21.71°C Runoff and canopy cover can affect temperature readings
Phosphate Levels GPS Points
Phosphate Averages Phosphate is a nutrient that encourages plant growth • 2008: 3 ppm • 2009: 1 ppm • 2011: 1 ppm Phosphate has stayed in the healthy range, but it still has room to improve
Habitat Assessment • The Habitat Assessment tests the: • Water Color • Bank Erosion • Stream bank Vegetation • Stream Cover • Water Odor • Stream Bottom • Flow Level • Habitat Variety
Habitat Assessment Comparison • Habitat Assessment is a test that measures the health of the habitat. • 2008: 27.1 • 2009: 25.5 • 2011: 25 • The Habitat Assessment Scores for the past three years have been decreasing slowly.

Biotic Index Score Year
Conclusion • Quality of the water has increased since 2007 • Habitat score of Barred Owl Branch is slowly decreasing • Biotic Index has improved over the four years of collection
Inferences • Water quality improved due to newly established vegetation filtering runoff • More runoff in watershed caused by more impervious surfaces • Biotic Index will continue to steadily improve
Action Plan • Continue monitoring Barred Owl Branch • Observe whether buffer zone is in place
