What can you do right now? As somebody said, you can try to pump some water in your pond until it rains.
But if you don't want the same situation in future, you have to think about digging pond deeper. Otherwise you can expect empty pond on 2013, on 2014 and maybe even every year.
Edit:
Aeration may help fish to survive. And better don't feed them much - some part of fish food won't be eaten and it will affect the quality of water (it wouldn't be so important in case when your pond would be full).
