Round Lake Stream drains around Lake into the Bog, most of it is barely navigable now, spring run off would be a wild ride. The carry around those rapids is rugged.
Likewise for the lower Bog, below the lower dam. Higher waters are required, carries are rugged.
I do know that lower Bog can be paddled in a stripper... Upstream on either is really not an option.
If you’re planning a loop trip, best to just bring a bicycle for a self shuttle, IMHO.
I have a bunch of pics I can link, maybe, I’m also having extreme difficulty posting from my pc
