Scovill Reservoir is also known to host a significant population of
bowfin, a large "primitive fish" which is common in the Southern United States but very unusual in New England. The fish was illegally introduced to the reservoir in the 1970s and has since become naturalized.
History
Indigenous era
Prior to settlement by the
Connecticut Colony, the broad region encompassing the Mad River was a hunting ground frequented by native
Algonquian people
The Algonquian are one of the most populous and widespread North American native language groups. Historically, the peoples were prominent along the Atlantic Coast and into the interior along the Saint Lawrence River and around the Great Lakes. T ...

The territory was known to these inhabitants as "Mattatuckoke", believed to translate to "place without trees",
and it correlated roughly to what is today referred to as the
Central Naugatuck Valley
The Central Naugatuck Valley is a region of Connecticut in New Haven and Litchfield counties located approximately northeast of New York City and southwest of Boston, United States. The region comprises 13 towns: Beacon Falls, Bethlehem, Ches ...

, local mills harnessed the waters of the Mad River to produce goods such as flour, cider and saw timber. The river's economic importance grew enormously as brass

manufacturing rose to prominence in the region in the mid-1800s. Several large factories in Waterbury relied upon Mad River to power machinery, even though it's modest watershed was prone to yield insufficient water flow during dry spells. Consequently, Mad River and a few of its tributaries were impounded upstream in rural Wolcott, creating a system of reservoirs which could be used to supplement reduced water flow during seasonal droughts.
Pollution
By the late 19th-century, the lower stretches of the Mad River were known to be tremendously polluted
Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the ...
by industrial operations. Factory waste, as well as sewage produced by growing communities, was discharged directly into the river. One observer of the Mad River in 1887 noted that water downstream of Scovill Manufacturing Company, one of the foremost brass producers in Waterbury, "showed extreme contamination; it was of a dark turbid color, with a strong odor and was covered with iridescent films of oily and greasy matters".
By 1970, passage of the federal Clean Air Act led to restrictions on the pollutants
A pollutant or novel entity is a substance or energy introduced into the environment that has undesired effects, or adversely affects the usefulness of a resource. These can be both naturally forming (i.e. minerals or extracted compounds like o ...

Recreation and conservation

Scovill Reservoir is a recreational reservoir which offers activities including fishing, boating, swimming and hiking. Wolcott's Peterson Park is situated along Mad River, as well. The CFPA Blue-Blazed Mattatuck Trail begins in the park and follows the river through a woodland setting.
Further downstream in Waterbury, the Hamilton Park encompasses a length of the Mad River and offers swimming, ice skating and hiking (in addition to sports fields that don't directly incorporate the river).
