Build a connection map as you watch
Start with a place or activity the film identifies, then note what it connects to: a movement of water, a use, a community or an ecological concern. Add arrows only where the film supplies the relationship. If you infer a connection yourself, label it as a question for later rather than quietly treating it as an established result.
For example, "the film linked this activity with a downstream concern" is a better note than "all places downstream must have the same condition." A connected system can contain important differences in location, timing and exposure. The map should help you follow the account while preserving those distinctions.
Ask which scale a claim addresses
A sequence about one location may illustrate a broader issue, but the relationship needs explanation. Listen for whether a statement concerns a particular site, one lake, the watershed or a more general environmental process. Keep figures and dates attached to the relevant scale when the film provides them.
After viewing, choose one claim you want to understand better and identify what evidence would answer it: a sampling record, a historical account or an explanation of a process, for example. You do not need to resolve every environmental question to have a useful conversation about how the film makes connections visible.
Keep present decisions tied to current information
The documentary is a creative work made in a particular period. A scene or historical statement cannot establish whether water is safe at a particular beach today, what a current local advisory says or the status of a present project. Use the relevant contemporary official source for those decisions.
If recommending the film, name McMahon and describe the connected-watershed subject. Keep Gord Downie's credited narration distinct from direction when discussing the makers. Check the official NFB record for the work and authorised viewing route; a separate interactive project or an excerpt is not necessarily the complete film. End with one connection you understand more clearly and one precise question for further reading. That gives a large subject a manageable shape without pretending one evening has answered everything about the Great Lakes.

Can a film scene tell me today's local water-quality advisory?
No. Check the current notice from the relevant local authority for a present-day swimming or drinking-water decision.
