How to review Oregon's Integrated Report
This story map will walk users through Oregon's assessment process for reporting at the assessment unit level
Oregon's Assessment Units
For Oregon's Integrated Report, water quality assessment conclusions are reported at an assessment unit level. Assessment Units are segments of streams/rivers or waterbody areas that are predetermined based on similar hydrology and represent similar environmental/hydrographic characteristics. Assessment Units can vary in size from less than one stream mile to greater than 200 stream miles. Assessment Units are further grouped into five distinct types.

Reviewing Non-Watershed Assessment Units
For river/stream, waterbodies (lakes, reservoirs and estuaries), coastline and marine assessment units data from individual monitoring locations are pooled to determine parameter categorical assignments.
Reviewing Watershed Assessment Units
The watershed assessment units are assessed differently than other units. In response to feedback on the 2018/2020 Integrated Report, we have modified how we assess the watershed units to include a more detailed accounting of where impairments exist.
