	abstract = {This study was undertaken for the Technical Committee, Canada-Alberta Flood Damage Reduction Program in response to concerns raised by the City of Fort McMurray over the validity of the elevation established in previous studies as representing the 1 in 100 year design flood level. The specific objectives were first, to examine the historic data and assess it reliability and second, to update the flood frequency analysis, incorporating additional data collected in recent years. The main conclusions arising from the study are: a) In spite of some limitations, the information available on the 1875 ice jam event and most other historic events is considered to be sufficiently reliable for inclusion in the flood frequency analysis, b) the 1 in 100 year break-up stage at Fort McMurray based on the updated frequency analysis is 250.0 m, and c) The estimated return period for the 1875 event is in the order of 350 years and corresponds to a flood stage 2.0 m above the 1 in 100 year stage. Designation of flood risk areas based on an historical flood that has exceeded the 1 in 100 year event is an option under the Flood Damage Reduction Program. However, given the extreme magnitude of the maximum historic event at Fort McMurray, it is felt to be unreasonable and inappropriate to designate to such a level. Instead, it is recommended that the updated 1 in 100 year breakup stage of 250.0 m be adopted as the design flood level for designation under the Flood Damage Reduction Program. },
