This is my second post, so I hope I'm doing it all right - feel free to let me know otherwise

I am planning a two night trip to Colo Meroo campground in March with another dad and our kids. We will be taking the short walk in from Upper Colo Rd. on a Friday evening so we can carry some extra gear.
Then Saturday I'd like to spend the day venturing upstream overland, then inflate some rafts and lilos and float/paddle/wade back to Colo Meroo.
I'm not sure if it's possible, but I am thinking about climbing up the Eastern ridge of Mount Townsend (west of Colo Meroo), then descending down the Townsend South ridge and getting into the river at the bend. I've attached a very rough idea of the route.
I have a few questions:
- Is it possible climb up the Eastern ridge of Mount Townsend from the river? It appears to be steep but have a fairly gentle approach.
- Is it possible to access the river from the Southern ridge or is it too steep at the bottom? (contours look very steep at the base, but happy to scramble).
- Is there a flat section at the bend to inflate lilos/ rafts?
- Has anyone been to Colo River recently? What is the flow like after all the recent rains?
- What is the approximate time to paddle/ float from Townsend Bend to Colo Meroo?
And finally if this sounds like a bad idea, have you got any suggestions of ways to hike upstream and paddle back down to the campsite as a day adventure.
Cheers.
