Oatka Creek Water Quality Assessment: Identifying Point and Nonpoint Sources of Pollution with Application of the SWAT Model by Dale Matthew Pettenski A Thesis submitted to the Department of Environmental Science and Biology of the State University of New York College at Brockport in partial fulfillment of the requirements for the degree of Masters of Science June 2012 Department of Environmental Science and Biology Thesis Defense by: Dale Matthew Pettenski Oatka Creek Water Quality Assessment: Identifying Point and Nonpoint Sources of Pollution with Application of the SWAT Model Date _________________________ Master’s Degree Advisory Committee Approved Not Approved _______________________________ ________ ________ Major Advisor _______________________________ ________ ________ Committee Member _______________________________ ________ ________ Committee Member _______________________________ ________________ Graduate Coordinator Date _______________________________ ________________ Chairman, Environmental Science & Biology Date ii Acknowledgements First, I would like to thank my advisor Dr. Makarewicz for giving the opportunity to work as a graduate assistant under the United State Department of Agriculture grant through the Research Foundation at the State University of New York at Brockport. I also would like to acknowledge Dr. Makarewicz for his insight, guidance and assistance through my project and thesis. Theodore Lewis also played a major role assisting with project guidance, ideas and SWAT Model aid. I give thanks to my committee members, Dr. Paul Richards and Dr. James Zollweg for assisting with ArcMap, the SWAT model and hydrological processes in Oatka Creek. I would also like to thank my SUNY Brockport colleagues Mellissa Winslow, Evan Rea, Blake Snyder and Will Smith for laboratory analysis and field work. Additionally, Tom Haley from the DEC, Greg McKurth from Wyoming County Soil and Water, Tucker Kautz from Monroe County Soil and Water and George Squires from Genesee County Soil and Water all gave valuable information on agricultural practices and GIS data within Oatka Creek. Lastly, I would like to thank Joyce Makarewicz for the time she took reading my thesis for grammar and punctuation. iii Table of Contents List of Tables………………….……………………………………..……………………….. vi List of Figures………….……………….……………………………………………………. vii Introduction….………………………………………………………………………………. 1 Segment Analysis……………………...….………………………….…………………. 3 Ecological Indicators………………………………………………….………………… 4 The SWAT Model…………………………………………………….………………… 6 Background: Genesee River Basin……………………………………………………… 7 Background: Oatka Creek Watershed…...…..………………………………………….. 9 Objectives and Goals……………….…………………………………………………… 12 Methods………………………….………………………………………….………………. 13 Study Sites……………………………………………………………….……………… 13 Weekly Water Chemistry Sampling…………...………………………………………… 14 Discharge…..…………………………………………………………………………….. 15 Wastewater Treatment Plants…….……………………………………………………… 16 Segment Analysis……………………..……………….………………………………… 17 Sediment Erosion Inventory….………….………………………………………………. 17 Macro-invertebrate Identification…………………………………….…………………….... 18 Soil Water Assessment Tool (SWAT) Model…………………………………………… 18 Model Setup……………………………….…………………………………………. 18 Source Inputs………………………………………………………………………..... 19 Model Calibration and Validation……………………………………………………. 23 Model Simulations………………………..…………………………………………... 28 Results…………………………………………….…………………………………………. 31 Nutrient Biotic Index…………………………………………..…………………………….. 31 Segment and Tributary Loading………………….……………………………………… 32 Discharge Measurements……………..………………………………………………. 32 iv Average Concentration…………….…………………………………………….……. 32 Event versus Nonevent Concentration…….………………………………………….. 33 Measured Total Annual Nutrient and Sediment Loading……….……………………. 33 Areal Nutrient and Sediment Loading…………….………………………………….. 35 Monthly and Seasonal Loading…………………………….………………………… 37 Chronological Account of Stressed Stream Analysis……..……………….……………. 37 SWAT Model Results…………………………………………………………………… 75 Sources of Phosphorus…………..……………………………………………………. 75 Effectiveness of Best Management Practices (BMPs)………….……………………. 76 Discussion………………………….…………………………………………..……………... 78 Water Quality Targets…………….………..……………………..………………………. 80 Oatka Creek in Comparison to Other Tributaries.…………….….………………………. 83 Efficacy and Limitations of SWAT…………………………..….……………………….. 84 SWAT Loading Allocations……………………………………...………………………. 88 Relative Losses from Subbasins…………...……………………………………………... 89 Evans Road…………………………………………………………………………….. 90 Warsaw Segment………………………………………………………………………. 93 Ellicott Segment………………………………………………………………………………….. 98 Garbutt Segment………………..…………………………………………………………….….. 101 Target Concentrations with Management Recommendations………………………………….... 105 Conclusions and Recommendations……..………………………………………………............. 106 Literature Cited…………………………………………...………………………………..…………..... 109 Tables……………………………………………………..………………………………....................... 115 Figures……………………………………………………...………………………………………..….. 129 Appendix A…………………………………………………...…………………………..…................... 190 Appendix B……………………………………………………...…………………………………...….. 196 Appendix C………………………………………………………..…………………….....………….... 198 v List of Tables Table 1.
