Abstract: In Canada, north flowing rivers are susceptible to ice jam formation that can lead to rapidly rising water levels and severe flooding. When river ice processes create ice jam conditions near populated areas, the potential for serious property damage and even loss of life is significant. To reduce the potential impact of ice jam flooding it is imperative that river ice processes be monitored and, where possible, managed. Alberta Environment monitors river ice processes throughout the province of Alberta. Based on potential impact and an established record of ice jam related flooding, two locations are closely monitored each year; the Peace River at the Town of Peace River and the Athabasca River at Fort McMurray. Both locations are located on north flowing rivers in northwestern and northeastern Alberta, respectively. Alberta Environment has had the opportunity to partner with various organizations in exploring new and innovative techniques for the monitoring of river ice processes and, where the river is regulated such as the Peace River using flow manipulation to manage river ice processes. These techniques have been developed and evaluated with a goal to provide local municipalities with more warning and information for emergency preparedness and response. This paper presents a description of the monitoring and operational challenges at the two locations and the new techniques that have been implemented or
