Scope and Purpose

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.

Projects and Resources

AgWG/AMS Review of Phase 6 Model

This project page is the repository for the Phase 6 model, its documentation, as well as files and links to Tableau pages, specifically as it related to the Agriculture Workgroup (AgWG) and Agricultural Modeling Subcommittee (AMS). Please email Lindsey Gordon (gordon.lindsey@epa.gov) with any questions you may have. 

The .pdf 'Draft Final Phase 6 Model Review: Comments Received for AMS' will be routinely updated and reposted as additional comments are received. 

 

Documentation

All documentation files will be uploaded to this FTP site to assist in partnership review of Phase 6: ftp://ftp.chesapeakebay.net/modeling/Phase6/Draft_Phase_6/Documentation/ 

Documentation of decisions made by the AgWG and AMS pertaining to the Phase 6 modeling tools is available below and will be updated with any additional decisions.

Calibration

A summary PDF of calibration results has been generated and is available for download (large file): ftp://ftp.chesapeakebay.net/modeling/Phase6/Draft_Phase_6/Watershed_Model/WSM_Outputs/Calibration_Figures/00_Calibration_Figures_All_Phase6Draft.pdf

Other detailed calibration results for each calibrated parameter and river segment can be found in a separate FTP folder: ftp://ftp.chesapeakebay.net/modeling/Phase6/Draft_Phase_6/Watershed_Model/WSM_Outputs/Calibration_Figures/

Further detailed calibrated output for the watesrhed can be found in csv files located at this FTP site: ftp://ftp.chesapeakebay.net/modeling/Phase6/Draft_Phase_6/Watershed_Model/WSM_Outputs/Summary_Loads/

Further comparisons between the Watershed Model and WRTDS can be found at the non-tidal dashboard. These visual representations show both the loads estimated from monitoring data (WRTDS) and loads estimated from the Draft Phase 6 Model: http://cast-beta.chesapeakebay.net/documentation/NonTidalWaterQualityDashboard

Land use files can be found at this ftp site: ftp://ftp.chesapeakebay.net/Modeling/Phase6/Draft_Phase_6/Land_Use/

Model Review Process

The process by which the partnership can most effectively submit comments and provide feedback to the development of the Phase 6 model will be outlined in a continuously updated document found below. The schedule of upcoming webinars is also provided below and in the attached document. Please contact Lewis Linker (llinker@chesapeakebay.net) or Kyle Hinson (khinson@chesapeakebay.net) with any questions.

Agriculture Workgroup Poultry and Swine Nutrients Reporting Template

States are to report updated nutrient concentrations by swine and poultry animal type annually as part of their reporting of yearly progress. This template is provided to aid states in the collection and reporting of the information to the Chesapeake Bay Program.

Agriculture Workgroup Rolling Timeline

The attached files outline the Agriculture Workgroup's deadlines and decisions calendar for the Phase 6 Watershed Model. Both an excel and .pdf version are attached.

This timeline is a living document, and will be regularly updated and reposted to this page.
