The recent science disputes that, and I've read it. Lake Winnipeg has collapsed before and it will collapse again. I think that is a risk that you need to really assess.
The other risk is the allocation of fish stocks. What's developed on Lake Winnipeg, for example, is a very high-value recreational fishery that is far more important to the Manitoba economy from a dollar and cents standpoint than the commercial fishery, and public bodies allocate public resources based on the highest and best use.
Have you factored any reallocation of the walleye fish stocks into your risk analysis?
