EPA Approved Integrated Report

The 2022 Integrated Report was approved by the U.S. Environmental Protection Agency on Sep. 1, 2022 and is now current and in effect. The federal Clean Water Act requires Oregon to report on the quality of its surface waters every two years. Although not a written report, the Integrated Report is a reporting of the status of water quality in Oregon and a list of waters considered to be impaired. See the Water Quality Assessment page for more information.

The Integrated Report can be accessed in four ways:

  • An interactive story map provides an overview of the water quality assessment process, displays assessment results and presents an overview of how DEQ’s water quality programs are connected through monitoring, assessment and watershed protection.
  • An interactive web map application that displays the Integrated Report by overall status of an assessment unit. The application also provides all applicable water quality standards. For assistance, see the web map instructions.
  • An online searchable database provides parameter specific categorical conclusions for all assessed units and raw data used for download.

  • An ArcGIS Assessment Geodatabase spatially displays information from Oregon's 2022 Integrated Report. GIS data is also available through ArcGIS online web services.

More information

The federal Clean Water Act requires the Oregon Department of Environmental Quality to assess Oregon's water quality and prepare a report every two years. The Integrated Report is a database that combines reporting information for the Clean Water Act Section 305(b) assessment of all water bodies and the Section 303(d) list of water bodies that do not meet water quality standards. The 303(d) list represents where pollution reduction plans called Total Maximum Daily Loads are needed. 

The 2022, Integrated Report represents the state's most comprehensive evaluation of water quality data and information about Oregon's waters. DEQ assessed data and information to determine whether Oregon's waters contain pollutants at levels that exceed protective water quality standards and do not support their beneficial uses. To complete this assessment, DEQ reviewed and assessed readily available data and information for the time period Jan.1, 2016, through Dec.31, 2020, using the Methodology for Oregon's 2022 Water Quality Report and List of Water Quality Limited Waters. 

The 2022 Integrated Report categorizes all assessed waterbodies. DEQ evaluated data on whether Oregon's waters are of a high enough quality to meet the most common beneficial uses, such as supporting aquatic life, providing drinking water or supporting recreation. Waterbodies that exceed protective water quality standards are identified as impaired and placed on the 303(d) list. Identifying a waterbody as impaired initiates the prioritization and development of a TMDL. ​

The categories are:
  • Category 1: All beneficial uses are supported, and none are known to be impaired. Oregon does not have sufficiently robust data to be able to use this category.
  • Category 2: At least one core beneficial use is supported, and none are known to be impaired.
  • Category 3: Not enough information to determine beneficial use support.
  • Category 4: Available data and/or information indicate that at least one designated use is not being supported but a TMDL is not needed.
  • Category 5: At least one beneficial use is not supported and a TMDL is needed.
