You bet! "they are the only experts"
We don't have many pools around, just lots of lakes, ponds, creeks and a few rivers.
Our back yard is a 7-8 acre pond, full of leeches, 2 families of beaver (and many other critters) and thigh-deep muck, pretty nasty, but likely FULL of nutrients along with all that muck.
When we first got bees we gave them fresh water daily, which they pretty much ignored in favor of pond diving and the water containers used for our goats and horse. When the lilly pads start blooming we'll take out the canoe, its a great time to 'water-spot' bees laping up water from the edge of the pads and then gather some nectur befor heading back, good times :)
With that said, in Spring I've had them ignore the dry pollen I've placed out in favor of rolling around in the cat-litter that's been spread around the garden perimeter :shock:.
