Pack rafts take more water than you would think. Particularly when floating out game. Those look pretty shallow in the pictures, but with a riverbed that sees seasonal water fluctuations. The good news is that they look glaciated and the rocks on the bottom are probably pretty rounded…
Packrafts gets holes in them pretty easily from dragging on the bottom (depending of course on the type of bottom of the river and the thickness of the bottom of your packraft) shallow or narrow water isn’t your friend when packrafting because of this.
I learned a lot about packraft capability when I was starting out from taking a packraft specific swiftwater rescue course. Key takeaway: just because you can doesn’t mean it will be fun or safe, but it’s probably doable… packrafts in general will take care of you in rough water. Maybe too well, because people seem to get into situations with packrafts that are well above their skill level and survive to repeat the same dumb thing over again until their luck runs out or their skill improves.
Not to be a discouragement at all, just get out there and learn by doing. There are quite a few Facebook groups for packrafting and people are pretty willing to have others join them for floats if they have a swiftwater rescue class under their belt. It’s kind of like a pre screen to see if you are legit or a liability before they place their life in your hands on a river trip since the barrier to entry is so low to get into packrafting.
Best of luck!
