Water quality was assessed in five stream segments in San Luis Obispo Creek and its tributary Stenner Creek in spring 2022. Two sites were selected along the San Luis Obispo Creek, and three sites along Stenner Creek. The stream segments were evaluated using the Surface Water Ambient Monitoring Program’s procedures for bioassessment of California streams. This procedure describes the collection of physical, chemical, and biological parameters including streamflow, substrate, flow habitat, and benthic macroinvertebrates toward a quantification of a California Stream Condition Index (CSCI). The California Polytechnic State University: San Luis Obispo, Stream Measurements and Water Quality course provided student labor for collecting and organizing data. The water quality of five stream segments within the San Luis Obispo Creek watershed were found to be acceptable to good quality based on the resulting CSCI scores.
