Pond about to breach its Bank

The pond at the end of our garden has started to overflow onto the grass next to it and if the rain continues the water will start flowing down the lane to the bottom.the drainage on the way done is not that good so it could gather at a certain point. Please could the pond be drained as much as possible please. Not only the sky feeds it but the road flows into it and our 3 bungalows here all feed it from the roof gutters
