What are the effects of harmful algal blooms?
Harmful algal blooms can:
Produce extremely dangerous toxins that can sicken or kill people and animals

The river looks bad. No one would drink from it, even totally inexperienced hikers.
You don't drink from rivers or lakes ever. Everyone knows this.
I have to agree. We are 4 mile easy/moderate hikers, but even our elementary kids know that even the cleanest looking water can be dangerous to drink.
I’m with the heat stroke group.
I have to disagree here. For a day hike, yes you usually carry all the water that you need. We have done multi day backpacking trips in the California mountains and you simply cannot carry all the water you need to drink. You must drink from lakes and rivers. You of course filter the water and stay up-to-date on water conditions and locations of water along the route. But it is generally pretty safe in many locations.
This isn’t really relevant to this particular case since I would’ve expected them to bring all the water they need it. However experienced hikers who do multi day trips might be comfortable with drinking water in lakes/streams
