About the grand river
The Grand River is a 300-kilometer long river that runs through southern Ontario, Canada. It was an important waterway for Indigenous peoples and European explorers and was later used for transportation and industry. The river originates in the highlands of Dufferin County and flows into Lake Erie at Port Maitland. The river’s hydrology is affected by numerous tributaries and reservoirs, including the Conestogo, Speed, and Eramosa rivers, and the Elora and Guelph Lake reservoirs. There are also several dams along the river, including the Shand Dam and the Guelph Lake Dam. The Grand River is used for water supply, flood control, and hydroelectric power generation. It is also a popular destination for recreational activities such as fishing, boating, and camping. The river is also home to several agricultural operations, including dairy farms and crop production.
