Salmon started getting up the ladder on or just before 29 March - a little earlier than last year - at a water temperature of 5.4C. At first fish just trickled through, but a larger pulse of fish ran through 22-26 April when the water temperature temporarily rose to close to 10C. At this stage, the count was ahead of last year's, but since then it has lagged a bit behind, and it is currently about 200 behind what it was on the same date last year.

The heron which specialises in taking eels at the foot of the fish pass each summer has now started paying visits to check things out, but the cooler water than normal this June means that eels have not yet arrived in any numbers, if at all.
