The Conestogo River flows through Wellington and Waterloo Counties in Ontario, Canada, offering a diverse and rewarding fishery for anglers of all skill levels. The river is perhaps best known for the productive stretch between Conestogo Dam and its confluence with the Grand River, a section that benefits from cold-water releases from the bottom-draw dam at Conestogo Lake. This tailwater influence creates suitable trout habitat for approximately 15 kilometres downstream of the dam, making the Conestogo a notable destination in the region. The river features a varied character, with a large deep pool just below the dam wingwalls that gradually transitions into shallow runs, fast-water riffles, and smaller deep pools, with large rocks scattered throughout the river course.
