From what I hear the Sierra's water is good to drink from the stream. Is this always the case? Or is it only good past certain elevation?

Many threads about this including the recent http://www.backpackinglight.com/cgi-bin/backpackinglight/forums/thread_display.html?forum_thread_id=68224
and Rog's article from a few months ago
Sep 19, 2012 at 12:06 pm #1913711Two things to consider:
1. A healthy, non-immunocompromised adult can tolerate a certain degree contamination by the usual nasties (cryptosporidia, giardia, et alia). This is exactly why we evolved immune systems.
2. A bottle of water purification tablets weighs a fraction of nothing.
For my part, I've drank a lot of water directly from the source, and I've never had a problem. But I seem to have a pretty robust immune system, and for what it's worth, I only drink untreated water if it "seems clean" (which, I admit, is a terribly unscientific criterion for a scientist to use! heh). But I am also aware that each time I take a drink from a rushing mountain stream, I am playing a game of gastrointestinal Russian Roulette.

5 days, 5 people, nobody treated a single liter of water that I am aware of.Everybody was fine.
Skill?
Luck?
Divine intervention?
Science?
Stupidity?
Arrogance?You decide.

If there is a small chance of getting sick from 1 day, say 1%
Then for one trip you'de have to be unlucky to get sick
But if you got sick 1 of every 20 trips you'de want to treat your water
To add to your list:
Statistics?
Sep 19, 2012 at 1:51 pm #1913746The higher up you are, the closer you are to the source and there is a less chance of having a dead animal upstream.
Sep 19, 2012 at 3:03 pm #1913771I just got over giardia that I'm pretty sure came from a recent sierra trip (SEKI). I usually don't filter and just try to get fast-moving, high-volume water up high. My luck ran out this time. The nausea and weakness I experienced were unpleasant enough that I am resolved to filter and treat my sierra water from now on. Not only is giardia unpleasant, but you don't want to have to put your body through a round of antibiotics if you can avoid it.
