As a beekeeper, you need to make sure there is a steady source of water for the bees. Putting hives near a natural source of water like a creek is best. I know a beekeeper who put a little decorative fountain right near his hives for the bees to drink. If you don't provide water, the bees will find it whether it's where you want them to or not. Many a beekeeper has been upset that the bees found water in their neighbor's swimming pool (much to the dismay of the neighbor).
So to prevent problems, I put up a bucket of water near the hive. You can see it here on the right of the picture:
In the bucket I put a lot of wood and sticks, as the bees need something to stand on in order to drink (bees have drowned in just a plain open water source). Last year I had a problem where my bees liked my neighbor's wood bucket and air conditioner condensation better!
Today the temperature was about 60, and I went out back to look at the hive. I was surprised at all the activity at my water bucket - there were dozens of bees drinking, and many coming and going. With the recent rains, the water is nice and "natural" (meaning kind of gross) - just like the bees like. Here's a video of the activity:
I also took some pictures, some closeups of the bees. Click them to see closer!
