Is water left in white plastic container that has turned green with algae still ok for large honey hives?

Ted,  
Bees prefer what we may perceive as 'dirty' water. Leaves that fall into water leach out minerals that can be important bee nutrients. Researchers have found that bees will preferentially select a water source that contains a mineral that is deficient in their diet.  
 
So algae in a water source has the potential to be beneficial because it will provide nutrients. One caution is that toxic algal blooms have increased in recent years. I'm unable to find any studies about the effect of toxic algae on bees. If the water in your storage container came from a drinking water source this shouldn't be an issue, but it might be a good idea to change it every so often to be safe.

Shelley,  
Glad you find this useful. It's so important for bee health to provide water, which is something that bee gardeners are often not aware of.

Where do you place the bees watering pan? I live in Texas where is can get to 105 degrees in summer. I'm afraid the shallow dish with marbles and water will get too hot in the sun plus would evaporate quickly. I keep mine under my covered porch near the native saliva.

Mary Michelle,  
It gets hot here in central California as well. I keep mine in a spot that gets morning sun and afternoon shade, and I need to fill it about every other day.  
 
My only concern with your location is that bees might not fly under a porch cover. They navigate by the sun and need to have the sky overhead.

i live in Eastern Washington state in the country and i have had honey bees coming for water at my pets watering bowl and soaker hoses in my garden and any leakey faucets i have. There are so many of them that we bump into each other. I have tried to find where they are going to but can't. My question is that i need to shut my water off soon due to winter , will that kill the bees?

Sherry,  
The honey bees you see are collecting water mostly to cool the interior of their hive. As colder winter weather arrives the need for this diminishes. When it's cold enough that your pipes might freeze, it's cold enough that the bees won't need your water source.

Mary,  
Glad you would like to take care of the bees that use your garden. Be sure to have something in bloom at all times; if you're in California the Haven's plant list is a good place to start: https://beegarden.ucdavis.edu/BeeGardeningResources

Would it work to place the dish in a plant container? Or does it need to be in a more visible location?  
 
Thank you for providing all this great information about taking care of the bees!

Nina,  
Glad you are finding the blog helpful. Please try placing your water source in a plant container and let us know how that works.

I made a pollinator hydration station from a rock that I smoothed out a shallow bowl, I have never seen any pollinators near it. It’s in my front flower garden. Today I noticed honey bees drinking water from my bog in my back garden. They were standing in the mud. Is there something I can do to encourage drinking from my front station as well? I would hate for a bee to fall into one of the pitcher plants or get caught in a fly trap while stopping at my bog for a drink.

Amanda,  
Bees tend to return to a water source once they've found it, and it seems they prefer your bog garden. Possibly the surface of the rock is too hot for them to stand in, while the mud is cooler. Could you create a muddy area away from the carnivorous plants?
