CAWS has established a statewide online water quality database. Its purpose is to compile the water quality data that are routinely collected as part of permit applications and make them available to the public instead of remaining in file folders within town halls around the state.

The data were compiled by CAWS members from public records from 2000 to present. The database is in its infancy, so the dataset is limited and currently only represents 53 towns. However, the database is a dynamic tool with the intent of being populated by its users, therefore with your help we hope it will grow into a more useful resource.

The database is searchable by town, water body name or DEP watershed number. The data can be further filtered to focus on tidal or freshwater ponds, watercourses, wetlands, etc. As the database gets more populated, more search options will become available.

The database is available by clicking here.

If you would like to contribute to the data set or if you would like to send us comments please contact Tom Ryder at waterquality@ctwetlands.org
