The Water Quality Portal (WQP) is a cooperative service sponsored by the United States Geological Survey, the Environmental Protection Agency, and the National Water Quality Monitoring Council. It serves data collected by over 400 state, federal, tribal, and local agencies. The WQP contains sample locations, physical/chemical, biological, habitat and metric results. The WQP is periodically updated with DEEP's water monitoring data, including volunteer water monitoring data. An ongoing effort is underway to populate the WQP with current and historical program data. The data is free and open to the public for download and use.

The CTECO Fish (and Macroinvertebrate) Community Data Viewer displays all inland freshwater fish community and benthic macroinvertebrate community data collected by either the CT DEEP Water Monitoring Program or the CT DEEP Inland Fisheries Division to-date. Data is available for viewing on a statewide map and users can search by town, waterbody, fish species, or macroinvertebrate family. Data can be exported and downloaded as a .csv file by town.
The goal of the Long Island Sound Integrated Coastal Observing System (LISICOS) is the development of a sustained capability to observe the Long Island Sound ecosystem and an adequate capability to understand and predict its response to natural and anthropogenic changes. The LISICOS website provides access to a wide variety of historical and real-time data, including water quality data, collected from Long Island Sound.
The Spatial Hydro-Ecological Decision System (SHEDS) Stream Temperature Database stores regional stream temperature data across multiple organizations and state agencies in the Northeastern U.S. Users can view stream temperature monitoring locations in Connecticut, including stations monitored by CT DEEP Water Monitoring Program, CT DEEP Inland Fisheries Division, and volunteer groups throughout the state. (Enter "CT" in the agency search filter to view only Connecticut data.) Using the database interface, the user can select and export a georeferenced station list as well as corresponding stream temperature data for each station.
