That is a really interesting aspect of this question in the context, geographically, of where we live.
As we move through Lake St. Francis between the Moses-Saunders dam and Montreal at Beauharnois, the islands in there are all part of the territory of the Mohawk of Akwesasne. They're quite exposed to the shipping traffic as it moves through that section of the river. There are a number of different islands that are particularly vulnerable. One that I mentioned already is Yellow Island. There's sort of a layer of sand that forms part of the basis of that island and, as you can imagine, it is very prone to erosion. The concerns are quite high with respect to erosion on the properties in the islands along that portion.
In terms of the support that's provided, one of the members of our study group is Mohawk and has provided access through to one of our sites, which is an island. Dr. Rennie can speak to it directly in terms of the work being done there. We're quite interested in that impact.
They are also quite interested in the potential impact where there is active erosion and the downstream transport of sediments may be fouling, for the lack of a better word, the habitat downstream. The native fish population might be then impacted in terms of spawning grounds or habitat. These are all concerns that we've had with our partners at Akwesasne.
