The Truax Dam, which was located on the Saugeen River in Walkerton, Ontario, for over a century was identified as a barrier to the upstream movement of the entire fish community while it simultaneously created a 1.5km headpond and interrupted natural biophysical processes within the river. Funded by Bruce Power LP, the dam was demolished in August 2019 with the removal expected to allow the re-establishment of natural flow and temperature regimes, as well as increase river connectivity and fish passage. In order to quantify the degree of change resulting from the dam removal, a long-term multifaceted before-after study was designed and implemented beginning in 2018.
