Thanks to the folks on the forum, I found my leaks. Putting soapy water inside the bag really worked!
Now, what's the best way to patch the holes?
The rivers are running high in Arkansas , it's spring break, and it's going to be in the 60s all week!
This is an emergency:)

Re: Float bag leaks
I would clean the fabric around the outside of each leak so that whatever patching adhesive you use will adhere well. Dirty, greasy (what were you paddling in? 
) surfaces may not allow adhesives to penetrate.
For my Voyageur Nylon/urethane bags, I use Seamgrip, the thin, penetrating stuff used for tent seams. It may not be necessary for you to use a patch piece over each hole, unless the hole is kind of large.
You could also use Aquaseal, which is thicker. It doesn't get into the Nylon outside fabric surface as well, but it's quite compatible with urethane bags.
I don't think much of PVC or vinyl-based bags, so I won't discuss Vynabond as a repair material. There isn't much substance to Vynabond. It's mainly a solvent that softens two vinyl surfaces so they will bond into one another. Even on PVC or "vinyl" bags, I think urethane Seamgrip will do as well or better than Vynabond.
