It's been a dry year and I went to a small local reservoir (Litton in Somerset, UK) to see how low the water was. I soon found something more photogenic - a family of swans were taking a shower under the dam. They sat there obligingly while I took a few shots, then came over to me, no doubt hoping for food (I didn't have any on me - sorry, swans!). After the swans had gone on their way, the water jets made for an interesting reflection shot.
