How clean is the Rotten Calder? Josh Maitland, Junior Secretary and member of the local angling club in East Kilbride has signed up to CRIMP to answer that very question. After attending the final CRIMP workshop in August, he visited the Rotten Calder last month to start his monitoring. There were a number of small stoneflies and mayflies on the wing that day and he may have found the last ‘Blue Winged Olive’ of the season in the sample. Disappointingly no caddis flies were picked up in his CRIMP sample, but let’s hope that the Rotten Calder doesn’t live up to its name – only time will tell in the months to come!
