Levels are still incredible here.
Oyacachi and Cosanga were both med/high the last 2 days. Jondachi was a nice med/high as well.
We keep on getting just the right amount of rain which is maintaining things very nicely!
You could do your own trip down the Upano. I might recommend just doing day trips on the whitewater section though. If you go over-nighting, you are committing to lots of flatwater, and as there are tons of access points, you don't need to do a multi-day unless you really want to.
As for renting boats, we are too busy right now to let any of our creek boats go, but Rodrigo in Baeza has creek boats to rent. You can get in touch with him at email@example.com
He also runs a sweet hostal in Baeza!
Let me know if you have any other questions,
