Water Management Protects Our Environment
Effective management of agricultural irrigation runoff and stormwater discharge is essential to protect local water quality and meet regulatory requirements.
About the Water Quality Management Plan (WQMP)
VCAILG prepares and submits Water Quality Management Plans to the Los Angeles Regional Water Quality Control Board (Regional Board) as required by the Ag Order. Updated approximately every three years, these plans outline the strategies, actions, and requirements needed to help growers meet local water quality standards and protect our shared natural resources.
- Latest approved WQMP: 2020 Water Quality Management Plan (PDF)
- Each Each Responsibility Area has its own section with:
- Membership and crop data
- BMPs survey results
- Water quality exceedances
- Required BMP implementation actions
How the WQMP Works
- Responsibility Areas: Ventura County is divided into 31 Responsibility Areas based primarily on Total Maximum Daily Load (TMDL) requirements, while also accounting for subwatersheds, drainage patterns, and crop similarities.
- Representative Monitoring Sites: Each Responsibility Area has one assigned water quality monitoring site that is considered representative of the larger RA.
- Enrollee Accountability: If monitoring shows water quality issues, landowner and grower enrollees in that Responsibility Area must implement targeted Management Practices (MPs).
Finding Your Responsibility Area & Requirements
To help our members, VCAILG has created a compliance summary handout for each Responsibility Area that contains all the specific information members need to know to meet waiver requirements. Each compliance summary includes:
- Responsibility Area identification
- Beacon Site and continuing water quality issues identification
- BMPs Survey participation notice
- Required Documentation to be kept on site
- Education requirement notice
- Resources information for BMPs assistance if specific funding is available in your area
- Required BMPs table (and online resource links)
- Responsibility Area by Parcel List
To get started, identify your parcel’s watershed on the maps in the following sections or search the Responsibility Area listing below. (Any parcel located on a border has been assigned to only one Responsibility Area.) Please email us at [email protected] if your parcel is not listed or does not indicate a Responsibility Area.
Print Your Compliance Summary
The next step is to download and print the compliance summary for your Responsibility Area (links below) or contact us and we can email it to you. Please note that each compliance summary includes online links to technical information about how to implement many of the BMPs and why these actions are important to protect water quality.
