We periodically review the data collected from the St. Louis River. If the data "passes", it is considered acceptable for the previous period. If not, we examine it in the context of our understanding of the limnology of the individual lake and other data (nutrients, chlorophyll, trends, etc.) and then either delete it from the database or allow it to be posted. For details of our QA/QC protocol go to the Instrumentation page.

As changes are made to the St. Louis River database they will be detailed here.
