The mean annual discharge of the Athabasca River at these monitoring stations is 2,790,000 dam³, 13,600,000 dam³, and 20,860,000 dam³, respectively, indicating the increasing discharge with progression downstream (AENV 2008).

Now let's have a look at the Athabasca. Hydrometric monitoring stations located in the headwaters (at Jasper), mid-river (at Athabasca) and lower river (at Fort McMurray) have been operated by the Water Survey of Canada (WSC) since the 1960s. As a major river system, the Athabasca is influenced by a variety of climate, terrain and landscape characteristics found within its basin. below Ft. McMurray.
