Re: Water in the backcountry
You should be able to go on google earth or something similar and figure out whereabouts some sources of water might be. Bare minimum I would mark any lakes or ponds nearby, just in case you have to drop down to get water. I recommend a filter too.
Google some different ways to treat water. I can’t stand the taste of those tabs, they leave me still feeling thirsty afterwards. I usually risk drinking poor quality water over putting tabs in, I only use them if it’s swamp water. A filter and a uv light, or a filter and some drops of bleach might be better.
Like others have said you’re probably over thinking it. Depending on the research I do I usually only pack my one litre bottle full and an empty 4 litre bag for getting cooking water and stuff. I’ll put a litre or two in the water bag if I’m unsure of the next water stop.
If you don't read the newspaper, you're uninformed. If you read the newspaper, you're mis-informed.
