Lake Diefenbaker does just that. It provides an ample supply of water that can be used, whether for our communities or for agricultural production. It makes water available in drier years.
We have had years in which there has been excess water, and it helps provide protection against flooding.
When it comes to agricultural production, it makes sure that producers have that stable supply of water they need to grow their crops, but it can be used to make water available for communities as well should they need a source of water.
