It was still between bridge 31 and 32 at 17.15 (AC). We saw it earlier but light not good hence blurry pics from my compact camera. Well done Brian Leecy for finding it ! Must be a candidate for the Golden Balls Award. I can't remember any earlier Calderdale records for this species.
Bridge 31 is the one at the Bacup Rd junction. The Mason's Arms is there - the turn off for Gorpley Clough. 32 is upstream - Littleborough direction.
We had been at Withens Clough Res. No sign of HH to be seen here but two Goldeneye females on res left while we were there.
