Burnt Bridge Creek is a highly modified, urban stream that flows westward 12.6 miles from its agricultural origins, through the heart of Vancouver, Washington, to its terminus at Vancouver Lake. This study analyzed water quality data collected in 2011-2017 for parameters such as temperature, dissolved oxygen, fecal coliform, TSS and nutrients along 11 stations in Burnt Bridge Creek. Statistical analyses included Kendall’s tau correlation analysis to evaluate significant increasing or decreasing trends, Mann-Whitney test to detect significant differences between recent and historical data, and Friedman Test with pairwise comparison to identify significant differences in water quality among stations. Water quality index scores were also computed. Water quality monitoring of Burnt Bridge Creek is ongoing, and results are reported annually.
