Shimmering water

I took advantage of the good weather and headed down to the river and took a fly rod along for the walk. As a couple of day's earlier I saw many rises. I spent the evening flicking my line out into the shimmering water. No big fish to tell any tales about just me and my thoughts on a warm summer night. I had no takers but others I spoke to had the same luck, a very low water level with the warm weather most likely cause or maybe I used the wrong fly. A fish would have been a bonus but I was more than happy to ponder down by the river :)
