Flow Estimates for the Current Year

The graph below shows the Athabasca River flow estimates (black dots) used in implementation of the Lower Athabasca Region Surface Water Quantity Management Framework for the Lower Athabasca River weekly management triggers and water withdrawal limits for the current year 2020. The table below presents the Athabasca River flow estimates used for the previous year.

The river naturally fluctuates throughout the year, with flows reaching their peak around July (approximately week 26 on the graph). As natural flow increases, so does the minimum flow required to maintain a healthy ecosystem.
