The smolt run is upon us again and we are seeing numbers of smolts increasing at Catrine Dam again this year. Since the small amount of rain we had last week, numbers are steadily increasing between penstock and lade and it seems only a matter of time until we will be facing a repeat of the 2018 and 2017 situations where thousands of smolts were held up unable or unwilling to continue their downstream migration through the by-wash arrangements.In current and previous configurations, there just doesn’t appear to be adequate attraction flow to encourage smolts to take that route.
Another recurring issue is also evident and that is that the screens are not entirely smolt proof and we’ve seen a few smolts on the voe side of them already this year. This means those fish have no way back to the river to continue migration and are effectively lost.
ART will now contact SEPA as a matter of urgency seeking an alternative strategy to protect this years smolt run as we can’t stand back and allow the delays that happened in the previously two years to repeat again this year.
Hopefully the rain over today and a few days ago will encourage a bit more movement. On the Doon, there were lots of smolts about yesterday, getting to the flies quicker than the trout as usual! A variety of sizes, but well fed and in good condition, hopefully they’ll be able to evade the avian predators at Doonfoot. Sadly, the first sighting of the year of a Mink rooting through the undergrowth on the opposite bank!
Yes there are a lot in the lower river following the freshet we requested earlier in the week. Hopefully they will head to sea and avoid the birds.
I have been up the river twice a day for three weeks and purposely been looking for smolt activity to the voes side of the barrier and have seen NO movement. Seems to be working better than suggested.
Well we have photos of smolts in the voes this year and SEPA were there when we proved this. The gaps were then covered with polythene and boards but for those in there, it is already too late but I accept that fewer are trapped behind the screens than last year. I expect had we not highlighted the issue, there would be far more by now. We remain unconvinced that the by-wash is an effective escape route for smolts particularly during low water and have evidence to prove this. It remains a concern for the board and I expect for SEPA too. 3 years of delays to the annual smolt run is an entirely unsaisfactory track record for the operators in our opinion.
