Mattabesset River Watershed map

Begun in 1992, the Mattabesset program is CRWP’s longest standing. The Mattabesset program has generated an extensive database of water quality information, and has raised local awareness of river resources and water quality threats. Data from 1992 to 1998 were summarized in a report titled The Mattabesset River: A Study of Water Quality and Stream Health. Information collected through CRWP has been used by municipalities to investigate potential sources of pollution, by the state for planning purposes, and in developing a comprehensive management plan for the Mattabesset Watershed.

Monitoring activities in the Mattabesset and Coginchaug Rivers—now in the 16th year—have included collecting and analyzing water and benthic macroinvertebrate samples at long-term sites; conducting physical surveys of tributary streams; and periodic visual inspections. CRWP staff have also conducted follow-up water quality surveys in tributary streams to locate failing septic systems and other pollution sources in Berlin, Rocky Hill and Cromwell. In 2004, CRWP cooperated with the CT Department of Environmental Protection (DEP) to collect samples used in developing a bacteria TMDL (Total Maximum Daily Load) for the Mattabesset Watershed.

Project partners include the watershed towns of Berlin, Cromwell, Durham, Guilford, Middlefield, Middletown, Newington, New Britain, as well as the Central Connecticut Health District, CT DEP, the State Public Health Laboratory and Xavier High School.

Hockanum River Watershed map

 

 

 

 

 

 

 

 

 

 


The Hockanum program was initiated in 1999. Community volunteers have assisted in conducting physical surveys of
the Hockanum River and its major tributary the Tankerhoosen River, and annual benthic macroinvertebrate surveys (rapid bioassessments or RBVs) of the Hockanum and Tankerhoosen Rivers. Bioassessment results have been used in local efforts to protect the Tankerhoosen River, and incorporated in a statewide RBV report produced by the CT DEP.

Project partners include the Hockanum River Linear Park Committee in Vernon, Hockanum River Watershed Association, North Central Conservation District, and the CT DEP.

Eightmile River Watershed map

The Eightmile program is being conducted in partnership with the community-based Eightmile River Wild and Scenic Study. Begun in 1999, monitoring activities have included physical surveys of the Eightmile River and its major tributary, the East Branch Eightmile River, and benthic macroinvertebrate surveys (rapid bioassessments or RBVs) of the Eightmile, the East Branch Eightmile and tributary streams. Activities have been conducted with the help of community volunteers and students from Three Rivers Community College. Summary reports have been produced each year, and bioassessment results incorporated in a statewide RBV report produced by CT DEP. CRWP data were used in the effort to obtain Federal Wild and Scenic Designation for the Eightmile River.

Project partners include the Eightmile River Wild and Scenic Coordinating Committee, made up of representatives of the major watershed towns (East Haddam, Lyme and Salem), the local land trusts, The Nature Conservancy, the Connecticut River Estuary Regional Planning Agency, CT DEP and Natural Resources Conservation Service.

Salmon River Watershed map

The Salmon program has included two separate efforts. In 2002, CRWP conducted a physical survey of the Jeremy River and headwater streams in Colchester in cooperation with the University of Connecticut Cooperative Extension System’s Salmon River Watershed Project. In 2003, an assessment of the upper reaches of the Blackledge River (a major tributary of the Salmon) was initiated in partnership with the Bolton Conservation Commission spurred by concerns about development pressure in the area. Members of the Conservation Commission and the community have assisted in conducting a stream walk survey and benthic macroinvertebrate surveys (rapid bioassessments or RBVs). Summary reports have been produced for each effort, and bioassessment results incorporated in a statewide RBV report produced by the DEP.

Project partners include the Salmon River Watershed Committee (with representation from seven major watershed towns and other stakeholders), University of Connecticut Cooperative Extension System, town of Colchester, CT DEP, and Bolton Conservation Commission.

Farmington River Watershed
map

The Farmington program is focused on the Pequabuck River, a major tributary of the Farmington. CRWP has conducted a water sampling and analysis program in the Pequabuck River watershed since 2002 in cooperation with the Pequabuck River Watershed Association (PRWA). Community volunteers and PRWA members have collected water samples from the Pequabuck River and two tributaries, Poland River and Copper Mine Brook. Samples have been analyzed at the State Public Health Laboratory and at several area university labs. Summary reports have been produced each year. Water quality data has also been incorporated into a State of the Watershed Report as part of a local effort led by the Central Connecticut Regional Planning Agency (CCRPA) and other watershed stakeholders, and were used in developing a watershed management plan for the Pequabuck River.

Project partners include PRWA, the Bristol-Burlington Health District, Torrington Area Health District, CCRPA, the State Public Health Laboratory, CT DEP, Wesleyan University and Saint Joseph College Freshwater Institute.
