Developing an Operating Plan for Lake Diefenbaker
Lake Diefenbaker is a critical water resource that provides multiple services for the province of Saskatchewan. It provides source water for half of the province’s population, including its two largest cities. It also provides source water for agriculture including the province’s major irrigation areas, various industries, mining, and aquaculture. For many people Lake Diefenbaker is prized for its recreational and aesthetic characteristics, which are important for increasing personal well being and attracting and retaining people within the province. Given Lake Diefenbaker’s central role in the economic, social and environmental fabric of Saskatchewan, it is vital to ensure this resource is well managed. Such planning must fundamentally aim towards balancing sustainable economic growth and a healthy environment. It is therefore important to undertake initiatives to better understand how factors affect the quantity and quality of water in Lake Diefenbaker so that the lake can continue to provide high quality water to meet the needs of the province. These factors include both human activities and natural processes (e.g. climate variability).

Stakeholder Consultation/Engagement Process
The Water Security Agency (WSA) wants to engage stakeholders in a meaningful and inclusive way. The consultation/engagement process is designed to seek advice from targeted local, regional, provincial, and federal stakeholders by presenting them with information on how the WSA currently manages Lake Diefenbaker and the problems and dilemmas associated with managing this important and complex system. The goal of the consultation/engagement is to challenge the stakeholders to help the WSA develop an optimal operation plan for the system.
Feedback gathered through the consultation/engagement process, along with technical and financial considerations will be used to inform the development of a new Lake Diefenbaker Reservoir Operating Plan resulting in more formal rules and operating procedures for Gardiner dam. The plan cannot be a static thing. It must be subject to revision and must recognize the potential impact of climate change and other extreme events in the future. The plan will ultimately be determined by government as a matter of public policy.
It should be noted that although the Qu’Appelle River and the diversion of water to the Qu’Appelle River is an important component in the operation of Lake Diefenbaker, it is not the focus of this stakeholder engagement process (at this time). The focus of this engagement process is the Saskatchewan River system. As such, the emphasis has been to engage stakeholders from organizations along the Saskatchewan River system. See Appendix A for the proposed list of stakeholders.
To encourage meaningful participation of the First Nations communities along the Saskatchewan River system, representatives from these bands have been invited to participate in the initial stakeholder engagement meeting. The subsequent sector sessions with the First Nations communities, with Chief and council have been proposed at either an individual band level or regional scale, depending on the band’s interests and availability.
