Smolt trap update

What a difference a week makes; this time last week the Avon smolt trap catch was ahead of the same date last year but one week on the running total is now well behind. In the six day period up to 26th April 2015 we caught over 2000 smolts in the Avon traps compared to 93 in the same period this year. Each year is different of course with snow featuring more than sun in the forecast on Speyside over the last couple weeks. The average river temp over that six day period this year was 5.3oC compared to 8.8oC last year. River levels have dropped over the course of the week whereas last year there was a small rise midweek. Still we are nearer the start of the normal smolt migration period than the end so there is time yet but it would be good to see the run increasing soon.

On the Tommore Burn the catch has been equally slow with one smolt trapped over the course of the last week. The temperature was only 3.1oC this morning but the snow over the last few days should produce a rise in water levels when the thaw arrives.
