jen, like jack and scott said, boardman's are a great way to provide water for your hives, just set them in the hive, or place them on your porch, myself i would probably do both, but they work really well set right in the hive.
bees need water all season. i don't worry too much about water, live on a river, and water from the gardens, but do use boardman's for new hives. no matter what you give them they will still find the stagnant water somewhere, or in the city a neighbors pool, your birdbath or the neighbors.
like pete said though, supply water of some fashion as he does well away from the hive. the bees short distance gps doesn't work well a short distance from a hive on something fixed, unless a boardman right on the hive, or it has rained, or some sprinkling system. with a short distance in close proximity of the hive they tend not to find it and are unable to communicate to their sisters that it's there.
