Description: This feature contains a spatial representation of the assessment units used for Oregon’s 2022 Integrated Report Assessment Database and 303(d) List. This feature should be used in conjunction with the feature AssessmentUnits_OR. A water body may have assessment information for multiple pollutants or conditions. Oregon’s 2022 Integrated Report Assessment Database and 303(d) List are available on-line at https://rstudioconnect.deq.state.or.us/content/0a964958-6ad4-49a4-aca0-54a644b96357/. The online searchable database should be used in conjunction with these features, and is the reference source to verify all attribute information about water quality and to obtain assessment information about water bodies that do not have georeferenced locations. Users may contact DEQ for information about Oregon’s water quality assessment process, additional updates to the 2022 IR, and the schedule for future water quality integrated reports. https://www.oregon.gov/deq/wq/Pages/WQ-Assessment.aspx
