Is Low's Lake Crowded Near the End of September?

[ReluctantFarmer]

Question more or less in the title. I have a weekend (three nights, two paddling days), and thinking of sinking them into the Lake but tons of commentary online is how crowded the Bog River section and Low's Lake (in the ADK) are, especially on weekends.

Was also thinking about the East branch of the Oswegatchie to the High Falls but I'm unsure if I want to spend the whole weekend dragging beaver dams and if anything the commentary suggests the crowds are just as dense.
