1. A Comparison of Two Creeks Kerry Caslow EAS 4480 Spring 2010 Level Creek, USGSRichland Creek, USGS

2. Site Information Richland Creek –Average stage is about 0.75 feet Level Creek –Average stage is about 3.5 feet USGS, 2010

3. Site Information Sites are 2.9 mi apart Same land use –Residential and parks Feed into Chattahoochee River Google Maps, 2010

4. Particles Studied Calcium – mg/L Magnesium – mg/L Hydrogen Ions – mg/L Dissolved Oxygen – mg/L Cadmium - µg/L Copper - µg/L Lead - µg/L Zinc - µg/L How do these particles correlate with stage?

5. Stage Height Histograms Stage Heights are not normally distributed Level Creek Richland Creek

6. Major Metals and Non-Metals Correlation Coefficients: Level Creek: Ca: -0.62 Mg: 0.47 H: 0.04 DO: -.004 Richland Creek: Ca: -0.27 Mg: 0.70 H: 0.05 DO: -0.31 Mean Stage @ Level: 3.89 ft Mean Stage @ Richland: 1.12 ft

7. Minor Metals Correlation Coefficients: Level Creek: Cd: 0.74 Cu: 0.39 Pb: 0.65 Zn: 0.57 Richland Creek: Cd: 0.55 Cu: 0.58 Pb: 0.66 Zn: 0.68 Mean Stage @ Level: 3.89 ft Mean Stage @ Richland: 1.12 ft
