Water Quality Programs

Biennial reviews of the Agricultural Water Quality Management Area rules and plans

The Oregon Department of Agriculture consults with DEQ during the review of area plans and rules, as required by Oregon statute. ODA’s outcome-based Water Quality Program is supported by agricultural water quality area plans in order to guide and encourage agricultural and rural land management activities that prevent and control water pollution. Area plans are living documents that are reviewed and revised on a biennial basis.

DEQ Nonpoint Source Program staff and basin coordinators provide data and analyses to ODA in status and trends reports during the biennial review process for area plans. These reports are designed to help ODA and agricultural land managers identify and implement strategies and actions that will protect water quality in their local agricultural management areas.

Status and trends reports are intended to achieve the following:
  • Review of available data for water quality trends and whether waterbodies are achieving water quality standards and meeting TMDL agricultural load allocations
  • Evaluating and providing comment to ODA on the suitability of landscape conditions to achieve TMDL agricultural load allocations


Agricultural Water Quality Management Areas: Water quality status and trends reports

Water quality status and trends reports are created on a biennial cycle for each Agricultural Water Quality Management Area (38 total AgWQ Management Areas in Oregon).

Completed reports are available online after the Local Advisory Committee meetings take place. The 2017-2018 Water Quality Status and Trend Reports are found below.
