This feature contains a spatial representation of streams and stream segments with water quality information from Oregon’s 2010 Integrated Report Assessment Database and 303(d) List as approved by EPA on March 15, 2012. This feature should be used in conjunction with the feature ORLakesWaterQuality_2010. 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 2010 Integrated Report Assessment Database and 303(d) List are available on-line at www.deq.state.or.us/wq/assessment/rpt2010/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 2010 IR, and the schedule for future water quality integrated reports. www.deq.state.or.us/wq/assessment/assessment.htm. This feature does not include additions to the 303(d) list that were proposed by EPA in March 2012.A ReadMe file accompanies the geodatabase and users are encouraged to see the document for additional details.
