River & Stream Water Quality Monitoring
Although Ecology’s Freshwater Monitoring Unit works hard to keep the information and data in these web pages accurate, reliable, and timely, we provide no warranties, expressed or implied. The data may be changed without notice to correct unforeseen errors.
We recommend that users of our data review our quality assurance (QAPP) documents, related annual reports (especially the appendix covering historical changes), and consult with the station contact person to ensure that our data quality meets their needs. Quality control data can be provided on request. Historical data (especially data collected before October, 1988) may lack any associated field quality assurance. It is the data user's responsibility to familiarize themselves with these and other qualifications, and to use data from this site with all appropriate caution.
