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.
