Heavy rain forecast but did not arrive until I'd fished for a couple of hours on the lower Chew. Water levels low and the river was wadeable for long stretches normally out of bounds. Lots of Dace about and some nice sized wild trout. The fish were rising infrequently to pick up Grannoms. Once again the odd Yellow May coming off. All my fish took the nymph. Thundery showers set in and cut my session short.
