San Diego Coastkeeper (SDCK) is working with Carlsbad citizens to create a new water quality testing team of the Aqua Hedionda Creek and surrounding watershed. Carlsbad currently has teams monitoring Buena Vista Creek (draining into Buena Vista Lagoon) and San Marcos Creek (draining into Batiquitos Lagoon). This new team will help track pollutants flowing into Agua Hedionda Lagoon. If you’d like to get involved, contact info@preservecalavera.org.
SDCK recently updated their online data from multiple watersheds throughout the county. The San Diego Union-Tribune article summarizes some of their results:
