A little note: As part of the Ottawa River Watershed, the source waters of the Madawaska River begin their 224 metre decent in Algonquin Park, draining over 8,700 square kms of wetlands, creeks and rivers.

Geologically young, the Madawaska River was carved with the melt waters of the Laurentide Ice-sheet, exposing the barebones of the the Canadian Shield, creating world class whitewater rapids between the lakes and flatwater sections as it makes the 230 km journey from Algonquin Park to join the Ottawa River, at Arnprior, Ontario.
