Two researchers have conducted a new measurement of a remote waterfall in northern Manitoba, indicating that it may be the tallest in the province. Alexander Martin and Lukas Olson used digital photogrammetry to measure Kapakaytay Falls on the Odei River. Their initial findings suggest a height of 16 meters, slightly surpassing the 14-meter Kwasitchewan Falls, traditionally regarded as Manitoba’s highest waterfall. Olson, a PhD candidate at the University of British Columbia specializing in photogrammetry, expressed confidence in the accuracy of their measurement. The falls, located on the Odei River, are situated around 40 kilometers northwest of Thompson and 690 kilometers north of Winnipeg, making them difficult to access.
The researchers embarked on a challenging paddling expedition to reach the falls in July, requiring meticulous planning, whitewater expertise, and wilderness navigation skills. The journey encompassed navigating rapids and logjams along a river flanked by fire-damaged forests. Local guides assisted Martin and Olson during their 105-kilometer round trip, culminating in a breathtaking encounter with Kapakaytay Falls.
Inspired by a previous expedition led by Winnipegger Garrett Fache in June 2019, Olson and Martin utilized over 1,000 two-dimensional images captured by a drone for their digital photogrammetry analysis. They also conducted laser measurements of surrounding trees and natural elements to enhance their model accuracy. While official topographic maps list Kapakaytay Falls at 58 feet (approximately 17 meters), the researchers’ model suggests a height closer to 52 feet, potentially surpassing Manitoba’s previously recognized tallest waterfall, Kwasitchewan Falls, which stands at 14 meters. Pisew Falls, located southwest of Thompson, measures 13 meters.
The province claimed that Kwasitchewan Falls retains its status as the highest waterfall based on their data. Olson and Martin are striving to publish their research, aiming to contribute to ongoing studies of Kapakaytay Falls. Their documentation of this remote site offers valuable insights and underscores the importance of continued exploration and documentation efforts.
