Ottawa River, River system between Quebec and Ontario, Canada
The Ottawa River runs 1,271 kilometers from Lake Capimitchigama east to the St. Lawrence River, forming much of the border between Ontario and Quebec. The waterway widens into several lakes including Victoria, Timiskaming, Allumette, and Deschênes, and is marked by numerous dams for power generation.
Samuel de Champlain explored the waterway in 1613, making it the main route for fur traders between Montreal and the Great Lakes. Later, sawmills lined the banks and timber drives shaped the region's economy into the 20th century.
The Algonquin called the waterway Kitchissippi, meaning great river, and traveled on it for thousands of years. Today boaters and anglers use its waters, while communities on both provincial shores maintain their connection to the channel.
Several parks and boat launches along both shores provide water access for canoes, kayaks, and smaller motorboats. Water levels can shift depending on the season and dam operations, so planning ahead helps for multi-day trips.
The waterway hosts 85 fish species, including rare sturgeon that dwell in the deeper sections. Every spring, thousands of migrating birds pass along its banks, making the channel a favorite spot for birdwatchers.
