Water Quality Index Score: 87, Good

The Rose Creek watershed, containing Rose and San Clemente Creeks, includes parts of Scripps Ranch, Miramar, Kearny Mesa, University City, Clairemont Mesa, La Jolla, and Pacific Beach. Of all the watersheds we monitor, Rose Creek had the highest water quality index score in 2016. This is mainly because nutrient levels were rarely elevated. Fecal indicator bacteria were still occasionally high though, concerning because this watershed drains into Mission Bay, a major recreational destination.

How to read our water quality pie charts:  these handy charts are designed to give you a sense of which of the factors we measured contributed to the overall water quality score (the number in the center) for each watershed. The size/color of the pie slice gets larger/warmer with increased frequency and magnitude of deviations from good water quality standards for each indicator.
