They get this water from places like bird baths rivers and streams and open pools of water but they risk drowning.
As for river and lakes bees risk their lives trying to get water in the presence of fishes frogs and other wildlife not to mention the risk of being swept away in water currents.

You can help give them an easier place to safely drink by as this post suggests placing marbles inside of a shallow bath of water.

In fact some think that is why they are attracted to pools because they can smell the chlorine and or salt.
Once bees discover the source of water they ll visit throughout the day but prime bee watching occurs just before sundown as bees take their last drink before returning to the hive for the night.
To help hydrate our little pollinators set up a water feeder by filling a pie pan with marbles and then water.
Bees work hard this time of year and need available sources of water to rehydrate.
One solution to this problem is to add marbles or pebbles to a bowl or pan and then add water.
