I think Ermineskin has spoken in support of the broad recognition of the right of self-government over water on reserve lands.
One of the more difficult parts of the bill is in answering the question of what the role is of first nation governments in the management of watersheds they're in, because that involves a number of other levels of government—provincial, federal and even sometimes U.S. federal and state governments. I don't have a whole suite of amendments on that issue, but I think the section of Ermineskin's submission prepared by Dr. Littlechild highlights the importance of article 32.2 of the UN declaration.
It says:
States shall consult and cooperate in good faith with the indigenous peoples concerned through their own representative institutions in order to obtain their free and informed consent prior to the approval of any project affecting their lands or territories and other resources, particularly in connection with the development, utilization or exploitation of mineral, water or other resources.
I think that would provide a benchmark in the bill for what it means for first nations to be involved in watershed management and source water protection.
