The stream is extremely low and clear, following a recent dry spell. The fish I can see are skittish, with shoals of roach and small chub spooking at any heavy footfall.
Luckily, there are some areas where I can get down to the water without making too much noise. In the first swim I try, a chub shows an interest in my micro jig, but a feisty perch dashes out from cover and ‘nails’ it.
After casting as tight to features as possible, the best way to work micro grubs is to bounce them slowly across the bottom, by twitching the rod tip in between half turns of the reel handle, with occasional pauses of a second or less.
