The bright cloud is about where the sun was coming up a few minutes later. This is why I left the cloud there, but you are completely right and also about the little cloud on the left side. I wanted to make a square crop at first, but then I preferred the photo with the blue sky above ;)
This reservoir is well visited by many people, but not on the path where I always go. I can count the people on one hand, which I have met there in there in the past year - this is a very safe place for a walk and then I need to go home to my family anyway :)
Thank you very much, take care and stay healthy @bashadow 🙂
