Most of my extensive camping was last winter so I melted snow.
I usually haul water for a camp trip that is only a few days.
Beyond that I would treat it with something, filter, boil, iodine etc. Don't take a chance on the giardia unless you can see the water coming out of the ground.
Funny I grew up in Montana and drank out of every stream I came to growing up.
Came to Alaska and got it drinking from a stream in the winter about 15 years ago. Holy cow you don't want to go there. That would make your hunting trip a drag.
A few years ago I also got what the doctor called Campylobacter
a few days after drinking from the Anchor river. They said it most likely came from a food but I say not. I thought I was going to die and went to the hospital to get rehydrated. I also missed the last 5 days of moose season either in bed or on the toilet.
Treat the water unless it is coming out of the ground is now my moto!
