Central Alberta reservoir study underway

Alberta’s government is moving forward a study to assess the feasibility of building a new reservoir on the Red Deer River to help support growing communities.

Demand for water from communities and businesses is increasing as more families, businesses and industries choose to live and work in central Alberta. The Red Deer River supplies water to hundreds of thousands of Albertans across the region and expanding water storage capacity could help reduce the risk of future droughts and meet the growing water demands.

Alberta’s government has now begun assessing the feasibility of building a potential new reservoir east of Red Deer near Ardley. A two-phase, multi-year study will explore the costs and value of constructing and operating the reservoir, and its impact on downstream communities, farmers and ranchers, and businesses.

“Central Alberta is a growing and thriving, and we are ensuring that it has the water it needs. This study will help us determine if an Ardley reservoir is effective and how it can be built and operated successfully to help us manage and maximize water storage for years to come.”

Reservoirs play a vital role in irrigation, drought management, water security and flood protection. Budget 2024 allocated $4.5 million to explore creating a new reservoir on the Red Deer River, at a damsite about 40 kilometres east of the City of Red Deer.

Work will begin on the scoping phase of the study as soon as possible. This will include reviewing available geotechnical and hydrotechnical information and exploring conceptual dam options. The scoping phase also includes meetings with municipalities and water users in the area to hear their views. This work is expected to be completed by December 2025.

“Reliable water infrastructure is essential for Alberta’s growing communities and industries. The Ardley reservoir feasibility study is a vital step toward ensuring long-term water security for central Alberta. As we assess this project’s potential, we’re supporting the sustainability of our economic corridors, agricultural operations and rural economy.”

“Water is essential to the agriculture industry and if the past few years are any indication, we need to prepare for dry conditions. A potential dam near Ardley could enhance water security and help farmers and ranchers continue to thrive in Alberta’s unpredictable conditions.”

Once that is complete, the feasibility study will then shift into a second phase, looking more closely at whether an effective new dam near Ardley can be safely designed and constructed, and the impact it may have on communities and the environment. Geotechnical and hydrotechnical investigations, cost-benefit analyses and an assessment of environmental and regulatory requirements will occur. The feasibility phase will also include gathering feedback directly from Albertans through public engagement. This work is expected to be completed by March 31, 2026.

Quick facts

• The Ardley dam scoping and feasibility study will be undertaken by Hatch Ltd., a Canadian multi-disciplinary professional services firm.
• Once the feasibility study is complete, government will assess the results and determine whether to pursue this project and proceed with detailed engineering and design work and regulatory approvals.
• Alberta’s government owns and operates several large reservoirs in the South Saskatchewan River Basin that help ensure sufficient water supply to meet demand from communities, irrigators and businesses, while also maintaining a healthy aquatic environment.
• Water stored at Gleniffer Lake, the reservoir created by Dickson Dam, helps supplement low winter flows along the Red Deer River and helps ensure an adequate water supply for Red Deer and Drumheller.
