"June 2021." Includes bibliographical references (pages 15-16). "Beaver Creek, a tributary of the Niagara River in southwestern Ontario, is classed as a municipal drain and is home to a population of Grass Pickerel (Esox americanus vermiculatus), a species at risk in Canada. In the fall of 2011 a section of Beaver Creek was subjected to drain maintenance. In an effort to mitigate potential harmful effects of the drainage activities on the Grass Pickerel population, reconstruction incorporating natural stream channel design features was also implemented. The fish community of Beaver Creek was sampled in the impacted reach where maintenance occurred, an adjacent control reach that was not subject to maintenance, and a downstream reach where the two converged, from 2009–2013 and again in 2015. A series of before-after-control-impact (BACI) analyses were conducted to determine the effect of maintenance and reconstruction activities on the Grass Pickerel population and the physical and chemical habitat in Beaver Creek"--Abstract.
