Haven’t worried about water for my bees as I have a permanent creek less than 150y from my hives. Plenty of rocks, trees, blackberries and grass hanging into the water so no trouble for them to get water.
Found my bees preferred water source while fishing today.
A sandy patch on the edge of the creek that is obviously the preferred watering point for my hives, watched them for a good 10min. There was a constant flow of bees with anything up to 20 or more bees at any one time sucking moisture from the sand. Interesting that despite a few small puddles in the sand only a couple of feet away and a flowing creek 3 feet away they prefer to gather moisture from the damp sand.
In a straight line its probably less than 150m from my hives to the sandy patch, after they had their fill they would take off in the direction of the hives do one small circle gaining elevation and then fly straight through a 3m window in the trees back to the hive.
