That is what I was thinking until the reply below.There are many small creeks and springs in most areas we travel so water has not been a problem.
I live in an area where surface water is everywhere. I am not sure that I would have problems with people coming to my place for it. I am not far from the Quabbin which is used to feed water to Boston, MA. But the thought of dead animals contaminating my sources never crossed my mind.Course these should be considered BACKUPS as fallout, chemical or biological contamination could render them unusable for an extended period of time. Also something as simple as a diseased animal falling in the water could start up the food chain sort of speak.
The bigger consideration is that OTHERS will be accessing ground water points. In other words, having the only lake in the area could be a detriment to you more than a blessing. Think about it.
And for the "can't we all just get along" crowd- consider that if you open up your land and water source to every Joe Blow that comes down the pike, your opening it up to contamination, both intentional and unintentional. Also, then it's considered a "resource" and pretty soon it's "hey man water is EVERYBODY'S."
You have to remember that with today's TV watching, "de owe's me!" socialist crowd, YOUR stuff is THEIR stuff in their mind.
You might think that letting a couple of folks in to get water from your pond would be helpful, pretty soon you'll have a group of squatters living on your place.
I am storing all my potable water. I was thinking of reducing the non-potable because of it's availablity. Venturing out to it could become an issue depending on weather. I would pass both sources during property/perimeter checks if the time came for them.I don't have a source on my current property, but even if I had multiple sources, I'd still store as much as I possibly could. I can see a number of reasons why I might not want to venture out to my source to get water, when having water stored would be safer. Or if there was a situation that caused my source to be contaminated beyond useability, or to stop flowing.
