Water Quality 2016: San Dieguito Watershed

Written by Meredith Meyers

Water Quality Index Score: 78, Fair

The San Dieguito watershed begins in the mountains north of Julian and includes parts of Ramona, Escondido, Rancho Bernardo, Solana Beach, and Del Mar.  Our monitoring data indicated that water quality was fair in the San Dieguito Watershed.  Like most of the sites our program watches over each month, fecal bacteria counts were often elevated, with 50% of the samples collected in this watershed in 2016 exceeding the water quality standard for Enterococcus.

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.
