1:30 PMNewport Bay Watershed Executive Committee MeetingThis meeting provides a framework for managing water resource issues in the Central Orange County Watershed Management Area.

Mission Statement

To develop regional management strategies to preserve, protect, and enhance coastal resources and surface waters throughout Orange County. A watershed approach considers the entire geographic area that a watercourse drains to address a broad range of issues.


A watershed is the geographic area draining into a river system, ocean or other body of water through a single outlet and includes the receiving waters. Watersheds are usually bordered and/or separated from other watersheds by mountain ridges or other naturally elevated areas.

Areas of Focus

OC Watersheds is a division in the Orange County Public Works department that coordinates watershed planning efforts, collects water quality, hydrologic, and meteorological data, develops large-scale water quality projects, moderates harmful chemicals in local waterbodies, and ensures countywide compliance with state and federal water quality regulations.
