Answer: We will leverage existing infrastructure and develop a long-term agreement with TransAlta that will see the Ghost Reservoir held at a low level during each high runoff season. We cooperated with Transalta on a trial of this in 2014.
This measure, along with other mitigation efforts like berms and dikes, will provide effective protection along the Bow River while minimizing the cost to taxpayers.
Question: What is your opinion on the proposed flood mitigation options for the Elbow River:
- Glenmore Reservoir Diversion Tunnel;
- The McLean Creek dry dam;
- The Springbank off-stream diversion and storage site and do you favour this project as a dry dam only or as a permanent reservoir?
Answer: Both the Glenmore Tunnel and McLean Creek projects are under consideration, but each project has its unique set of challenges and drawbacks. As we move forward we will continue to work with leaders and engineers in the City of Calgary to ensure the city is protected.
Preliminary environmental assessment, cost-benefit analysis and engineering studies showed the Springbank Dry Dam is the best option for large upstream mitigation and protection along the Elbow River. We are currently involved in ongoing and productive discussions with landowners.
Work on many community-level mitigation projects is also underway. Budget 2015-2016 includes funds for the Springbank dry dam as well as nearly $15M in grants through the Alberta Community Resiliency Program to the City's identified priority flood protection projects.
