The purpose of the CAWS state wide water quality database is to compile 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 collected from local consulting firms as well as the extensive records collected by the Connecticut DEEP.  In total the database contains nearly 30,000 records from well over 250 water bodies throughout Connecticut from 1935 to 2008.

The database is a dynamic tool with the intent of being populated by its users, therefore with your help it can grow into a more useful resource.
The database is searchable by town, water body name or DEEP 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 currently unavailable online.
