To better access the information we collect, GCWIN has established a publicly accessible water quality database that holds all the water quality data for the county.  In 2018, we migrated our data over to a new database called Ambient Water Quality Monitoring System (AWQMS).


How do I access GCWIN's data?

1.  Go to the AWQMS website:

                    (click here)

2.  Enter the following information:

           Username:  gcwinpublic

           Password:  public


3.  Choose how you want to find/view data (graph, maps, or exports).

4. Below you will find detailed videos of how to use the database. For more questions, please contact Mary Price at or by phone (970) 627-8162.



 Data Migration



  • We are currently in the process of migrating our data over to Ambient Water Quality Monitoring System (AWQMS) so all of our data may not be available at this time. 

  • This new database has many features, which we are fine tuning to make it easier to find and analyze data within Grand County.

  • If you cannot find certain data in AWQMS please contact Mary Price at for all other data inquiries. 


Thank you for your patience.
