There are about 25 or 30 lakes within the Yukon, but it doesn't have to stop there. If somebody wishes to create a lake, it's more about the details of the lake in terms of input water, output water, that sort of thing. If it's a completely contained lake and there's no problem with oxygen during the winter, then I would suggest it could be a candidate.
