We will gather feedback over the next 2 years on 3 possible options to help reduce the effects of flooding and drought along the Bow River by increasing water storage capacity.

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.

Your input will help identify the environmental, technical, financial and social impacts of 3 possible mitigation options identified in the Bow River Reservoir Options Phase 1: Conceptual Assessment – Main Report:

  • "Morley" – a new reservoir between Seebe and Morley, on Stoney Nakoda Nations reserve lands
  • "Relocated Ghost Dam" – an expansion of the existing Ghost Reservoir
  • "Glenbow East" – a new reservoir between Cochrane and the Bearspaw Dam at the western edge of Calgary

Engagement status

  • Open

  • Results under review

  • Completed

Who is listening

Ministry of Environment and Parks

  • Phase 1: Conceptual assessment

    Included a high-level hydrological study, tabletop geotechnical investigation, conceptual reservoir design and public engagement.

    November 2018 to Spring 2020
  • Phase 2: Feasibility study

    Includes a detailed hydrological study, on-site geotechnical investigation, cost-benefit analysis, public engagement and selection of a recommended option.

    Spring 2020 to Spring 2023
  • Phase 3: Engineering and regulatory approval process

    Includes detailed design and engineering of the recommended option, and pursuit of all required regulatory approvals.

    Summer 2023 to approximately 2027
  • Phase 4: Procurement, construction and commissioning

    Includes construction of the approved option.

    Approximately 2027 to 2032

Get involved

This engagement will have multiple phases and many ways to get involved over the next few years. More opportunities to provide input will be shared when available. Check back or sign up for updates

Participate online

The following opportunities are currently available on the online engagement tool:

  • Interactive map – let us know how you use the land around the 3 areas under consideration
  • Ask our experts a question

Take part online

Indigenous engagement

We will work directly with Indigenous communities and organizations throughout the Bow River Reservoir Options engagement to ensure their perspectives are heard and explored.

Virtual information centre

The Bow River Reservoir Options virtual information centre was available from June 16 to June 30, 2021.

The virtual centre featured information boards, a video and reports to help people learn more about the initiative and the feasibility study. It also included opportunities to share input on the reservoir options.

Learn more about the information shared and discussed during the time the centre was open:

Virtual live sessions

Participants were able to share feedback and ask questions during virtual sessions held June 22, 24 and 26, 2021.


Your feedback will help us carefully review the 3 proposed options for reducing the effects of flooding and drought along the Bow River and will be considered in any decision to move forward with one of the options.

If one of the options is chosen to move forward, it would proceed to the engineering and regulatory approval process.
