Dru Posted December 20, 2004 Share Posted December 20, 2004 I filter when I'm taking water from a lake or pond. Otherwise I usually don't bother, unless it's an area that sees a lot of traffic. i am interested in the rationale behind this one. what do you think happens in a lake or pond that doesn't in a stream? is there some sort of magic dam that stops the pathogens from getting out of the lake into the stream Quote Link to comment Share on other sites More sharing options...
Ireneo_Funes Posted December 20, 2004 Share Posted December 20, 2004 You haven't heard about the magic dam? I guess my thinking is that lakes are going to collect more waste than a given spot in a creek, because they're not getting flushed out as quickly. Also because the spot on a lake that I'm likely to be collecting water (just off the shore) is also the place where there's most likely going to be waste from animals/humans camping nearby. And I don't usually take water unfiltered from streams draining lakes. The farther upstream the better I figure. I know it's not very scientific, though.

Dru Posted December 20, 2004 Share Posted December 20, 2004 The highest fecal coliform count I have ever recorded when testing water quality was 16,000 and that was from a stream, not a lake. Lakes tend to have a higher water quality because they are big enough to dilute the streams that flow into them. Quote Link to comment Share on other sites More sharing options...
Ireneo_Funes Posted December 20, 2004 Share Posted December 20, 2004 But a lake's water quality isn't uniform, is it? I mean, it's going to be different at the shore vs. the middle, right? Quote Link to comment Share on other sites More sharing options...
Dru Posted December 20, 2004 Share Posted December 20, 2004 Why? Diffusion and mixing occur relatively rapidly. The only major difference is going to be vertical, eg. across the thermocline Quote Link to comment Share on other sites More sharing options...
Ireneo_Funes Posted December 20, 2004 Share Posted December 20, 2004 So is the water cleaner at the top or the bottom of the lake? Whatever, I'm sticking with the magic dam theory... Quote Link to comment Share on other sites More sharing options...
Dru Posted December 20, 2004 Share Posted December 20, 2004 How are you going to get to the water in the bottom of the lake to drink it? Swim out an dive down? Quote Link to comment Share on other sites More sharing options...
Ireneo_Funes Posted December 20, 2004 Share Posted December 20, 2004 No, I'm just asking. Is there more shit at the bottom of your "thermocline" or at the top? Quote Link to comment Share on other sites More sharing options...

Ireneo_Funes Posted December 20, 2004 Share Posted December 20, 2004 So what's the highest (bovine) fecal coliform count you've ever recorded in a cc.com thread? Again, just asking. Quote Link to comment Share on other sites More sharing options...
