    Final Streamflow Classifications

    Metadata Updated: April 12, 2025

    The following stream flow classifications on the map are final and include input provided during the public comment period.The State of Connecticut Stream Flow Standards and Regulations (Section 26-141b-1 to 26-141b-8 of the Regulations of Connecticut State Agencies) define four stream flow class standards:Class 1 is described as a free flowing streamClass 2 is described as minimally altered stream flowClass 3 is described as moderately altered stream flowClass 4 is described as substantially altered stream flowThe regulations include consideration of 18 factors related to the degree of alteration in stream flow when adopting river or stream system classifications. Spatial data for each of the factors was gathered from a variety of best available sources. These sources were available at varying scales. A methodology was developed to consider all 18 factors and determine the class for a particular stream segment. In addition, public comment was solicited and considered to identify the final stream flow classification.For additional information on the classification process, see Section 26-141b-5 RCSA Adoption of river or stream system classifications, Fact Sheet for Stream Flow Classification Process under Section 26-141b-1 to 26-141b-8 of the Regulations of Connecticut State Agencies, Technical Support Document Methodology for Defining Preliminary Stream Flow Classification, and Final Stream Flow Classifications and Statement of Reasons Document. These documents can be found on the CT DEEP website at www.ct.gov/deep/streamflow.
