Bow River Reservoir Options engagement

Albertans shared input on the Bow River Reservoir Options Initiative as part of the Phase 2: Feasibility Study.


Albertans provided feedback on possible options to help reduce the effects of flooding and drought along the Bow River by increasing storage capacity. Your input will help us identify and assess the potential socio-economic, environmental, and other impacts of each option.

Additional water storage will significantly reduce the impact of severe weather events on Albertans who live, work and recreate in the Calgary area and on the provincial economy. Flooding that occurred in southern Alberta in 2013 alone caused more than $5 billion in damage in Calgary and surrounding communities.

Feedback gathered will help determine which reservoir option, if any, should proceed to the next phase of the process. If an option proceeds, any feedback received will also inform future phases of the engagement.
