High Dam Tarn

The rain stopped, the sun came out, we went swimming. It was a toasty 16°C, very pleasant. I swam round the island and spotted these flowers at the edge. I've not identified them but will keep searching. The air was still, beautiful reflections (extra) but lots of midges. 
PS, Blip experts tell me the flowers are Bog Bean, shame they don't have a prettier name.
