Yeah as I figured it's not as simple as Dowly implies. For example stream water can also suspend Guardia.

Deep areas of large lakes may be one of the safest places to fill your bottles. Furtman recommends staying away from shorelines or streams, unless the water is going to be boiled for cooking, because beavers travel there and moving water can suspend Giardia.
