Bees need very shallow water to drink from. However, shallow water evaporates quickly. Birdbaths are not the best option as bees tend to drown if the water is not be shallow enough. 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.
To help hydrate our little pollinators, set up a water feeder by filling a pie pan with marbles and then water. The marbles give the bees a spot to land so that they donít drown when they come to drink. No more drowned bees!
