We record water temperature data across the Ayr catchment that feeds into the Scottish River Temperature Monitoring Network and helps identify areas on rivers that would benefit from such actions as tree planting.

I visited the two upper most monitoring sites today to download data; one near Glenbuck and the other at the top of the Glenmuir Water on the Shaw side of the catchment.
Both loggers were due for change before the end of the month but both had stopped working some time ago. There appears to be a battery issue with these loggers and we have let MSS know so they can check others too. Unfortunately, as the loggers had died, I couldn’t replace them but did manage to download the data they had recorded. Water temperatures peaked around 24ºC last summer and that’s high enough for our liking but not unusual. Predicted water temperature rises over the next 50 years as a result of climate change could be lethal to salmon hence the focus on this work in the first place.
Anyway, it was a lovely day to be out on the river working. When in the Glenbuck area, I checked for juvenile trout in the Stottencleugh tribs to see if I could see any that may be as a result of the small hatchery/incubator we ran last winter. I managed to spot a few.
I also looked at the willow cuttings we planted next to the new channel built to allow the road to be straightened. I was disappointed to see that some had been mowed. This area would benefit from allowing the river bank and a decent buffer to grow wild and provide shade and cover for fish (as it used to be. I may call the council and see if we can encourage a slight change to their management approach.
I noted that Ash ‘Die Back’ has killed the nice Ash tree that stands near our logger. This was alive last year but there’s not a single leaf on it now. It is worrying the number of Ash trees we are seeing dying or dead. There were a good number of trout parr scooting around in these wee pools and that’s encouraging.
