Semerwater in Raydale, just off Wensleydale. This is the second largest natural body of water in the Yorkshire Dales, after Malham tarn. It was left behind after the last ice age receded. Now, it is a haven for local birds. I can certainly say that there are a lot of birds, as I had them honking and squawking all around me while taking the night photos, and it was quite impressive to see flocks of some kind of bird flitting in front of the moon.
