Numerous organizations and agencies collect data in the watershed, some going back well over 20 years. Water quality data is of particular importance due to its effect on human, plant, animal and overall system health. The Las Virgenes Municipal Water District, Heal the Bay, the Resource Conservation District, the City of Calabasas and many other agencies have collected data in the watershed over the years. Current watershed-wide efforts can be tracked via the Monitoring Table. In 1999, the Monitoring Subcommittee of the Malibu Creek Watershed Council, recognizing the potential for overlap and duplication, created the Draft Malibu Creek watershed-wide monitoring program. The program calls for coordinated, uniform water quality testing at sites throughout the watershed. After one year of baseline testing and analysis, testing will be focused at "hot spots" of chronically high levels of pollution. Hot spot testing will help isolate sources of pollution and will eventually result in project and program ideas aimed at reducing non-point source pollution. The goal is make the best use of limited pollution prevention funds to restore and protect the coastal waters, streams, and lakes of the Malibu Creek watershed.

In creating its new Total Maximum Daily Loads (TMDL) regulations, the State Water Resources Control Board - Los Angeles region has been consolidating existing water quality data as well as conducting their own studies. To learn more about planned TMDLs and updates to the impaired waterbodies (303(d)) listings, visit the Region 4 State Water Board's website. Malibu Creek regulations are broken down by various waterbodies, listed alphabetically. For a visual picture of waterbody impairments, check out the Malibu Creek Watershed impaired waterbodies map.
