This feature contains a spatial representation of streams and stream segments with water quality information from Oregon’s 2012 Integrated Report Assessment Database and 303(d) List. This feature should be used in conjunction with the feature OR_Lakes_WaterQuality_2012. A water body may have assessment information for multiple pollutants or conditions, and may have multiple data records associated with the spatial representation of the water body or segment of the water body. Oregon’s 2012 Integrated Report Assessment Database and 303(d) List are available on-line at http://www.deq.state.or.us/wq/assessment/rpt2012/search.asp. The on-line 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 2012 IR, and the schedule for future water quality integrated reports. http://www.deq.state.or.us/wq/assessment/assessment.htm.Note: Duplicate RecordIDs exist in the dataset due to an EPA listing error. This includes Record #s 6550, 8025, 20340, 20847, and 21121 in the data. A ReadMe file accompanies the geodatabase and users are encouraged to see the document for additional details. |
