Flooding
Like all rivers, the North Saskatchewan is subject to periodic flooding, beginning with rapid snowmelt in the mountains or prolonged periods of rain in the river basin. With the establishment of permanent communities along the river's course, and the rise of an administrative/government structure, records exist recording floods in the North Saskatchewan for the past century. The Bighorn Dam, constructed in the early 1970s near Nordegg, Alberta, and the Brazeau Dam, constructed in the mid-1960s, have both dramatically reduced occurrences of flooding in the North Saskatchewan River.

The flood of 1915
The 1915 flood of the North Saskatchewan River was one of the most dramatic in the history of Edmonton. On 28 June, the Edmonton Bulletin reported the river had risen "10 feet in as many hours." A frantic phone call from Rocky Mountain House alerted local authorities to the flood's arrival. The Canadian Northern Railway had parked a number of train cars on the city's Low Level Bridge to protect against the "tons upon tons of debris" that had been pushed up against its piers, including a house swept away by the current. Thousands of Edmonton residents watched the flood destroy lumber mills along the city's river valley.
