Effects of dam removal on stream ecosystems

Dam removal at Fall River in Greenfield, MA

Duration

July 2015 - January 2018

Narrative

Concerns about safety and interests in restoring stream connectivity
have increased dam removal in the last two decades. This research
investigates the effects of dam removal on stream ecosystems. We
will quantify dissolved oxygen and temperature upstream, within, and
downstream of impoundments at 12 sites in MA. Eight of the sites
are slated for dam removal in 2015 and 2016, and we will quantify the
effects of removal on dissolved oxygen, temperature, and other aspects
of the stream ecosystem. Data will be useful in understanding the extent
to which dams impair stream ecosystems and quantifying potential
improvements in water quality following dam removal. Potential
improvements can be used to leverage support for dam removal and
help to prioritize dam removals that will maximize ecological benefits.
