recently, the very idea of the Still River supporting a healthy population of fish was
preposterous. In fact, most people from the area still harbor the incorrect notion that
the River is a dead zone," devoid of aquatic life.
There are some recent studies that provide documentation of the
biological comeback of the River :
In 1991, the Connecticut Department of Environmental
Protection (DEP) Fisheries Unit conducted a survey of the River just upstream and
downstream of the confluence of Limekiln Brook in Commerce Park (our project site). The
1991 survey found an absence of fish in the River, except for a few suckers. This is
indicative of stressed water quality. It should be noted that the 1991 survey occurred
prior to the upgrading of the Danbury Sewage Treatment Plant, so it can be considered
baseline (i.e., preliminary to the improvements to the River).
- In 1997, the DEP Fisheries Unit returned to the same site for a fish
survey. The 1997 survey occurred subsequent to the upgrade to the Sewage Treatment Plant,
which dramatically reduced pollutant loadings of ammonia and oxygen demand. The 1997
survey, in contrast to the study done in 1991, discovered a vast diversity of finfish,
including darters, shiners and pickerel - species that are limited to high water quality.

- In 1998, DEP returned to the same site and discovered a further increase
in the abundance and diversity of fish. The 1998 survey discovered large mouth bass in the

The presence of fish in the Still River is an exciting
measure of proof that the River has come back to life!
