Effects of Dam Removal on Stream Ecosystems

July 2015 - January 2018


Participating Agencies

  • Massachusetts Division of Ecological Restoration

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.
