This feature contains a spatial representation of lakes, ponds, and reservoirswith water quality information from Oregon’s 2010 Integrated Report Assessment Database and 303(d) List as approved by EPA on March 15, 2012. Water bodies in this feature are represented as points at the centroid of a polygon and the attribute table contains the assessment data associated with that water body. Spatial information for the water bodies as polygons is provided in the feature ORLakesAssessed_2010. These features should be used in conjunction with the feature ORStreamsWaterQuality_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 this geodatabase, 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. This layer 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.
