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).

 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.
