About
The charge of the Agriculture Workgroup is to provide expertise and leadership on development and implementation of policies, programs and research to reduce pollutant loads delivered from agricultural lands and animal operations to upstream waters and the Chesapeake Bay. The workgroup reports to the Water Quality Goal Implementation Team. Functions include:
- Provide a forum for discussion, exchange of information and evaluation between federal, state and local agencies, conservation districts, universities, agri-business and the corporate sector on sustainable and/or cost-effective agricultural production systems that benefit water and air quality.
- Provide recommendations on the prioritization of federal and state technical and financial resources on specific practices in priority watersheds.
- Provide technical expertise and leadership to support the development and implementation of agricultural elements within the Chesapeake Bay TMDL, Watershed Implementation Plans, two-year milestones, and tracking and reporting mechanisms that support an adaptive management approach towards Bay restoration.
- Coordinate with WQGIT Watershed Technical Workgroup to identify, define, quantify and incorporate pollutant reduction and conservation practices on agricultural lands and animal operations into the Chesapeake Bay Program decision support system. Provide data and support for the Water Quality Goal Implementation Team and Technical and Support Services.

Meeting Resources
The AgWG uses the following resources to track the Agriculture Workgroup's past and present actions and decisions throughout the development of the Phase 6 and Phase 7 models:
- Agriculture Workgroup Actions and Decisions 2010-2025
- Agriculture Workgroup and Agricultural Modeling Subcommittee Decisions on the Phase 6 Model
In July 2025, the AgWG endorsed a prioritization document that will be used to identify priority topics for the workgroup through the end of 2026 and provide a framework for agenda building and project development.
