Fished Ty Mawr today from about 1 until 4 p.m. after the casting clinic. Was surprised, but delighted at last, to see steadily rising fish (mainly sipping), until about 2.15. Who knows when they started? Some LDOs, YMs, OUs, sedges, midge and LBDs provided a smorgasbord of potential early afternoon fodder. Having fished hard last Wednesday for five hours, either side of midday, for just three fish, with few fly and hardly a rise, the change from 11 to 13 degrees water, and a max of 14 degrees on Wednesday to a balmy 19 degrees air temperature today, and for the first time for a while, blessedly hardly a breath of wind, instead of a cutting upstream north-easterly, must have made the difference. I had ten fish variously of 10, 12, 14 and 16 inches, the latter two of 1.5-1.75lb. After the “rise” ceased, there were still fish to be found sipping in the margins and all of the fish caught then were taken on a LBD Duck’s Dun variant, which I went to as there were a few tempting LBDs floating down in the slack water. Why would fish become obsessed with midge feeding when just one LBD must provide about 100x more nutrition?! Glad they obliged anyway! Caught fish on HE emerger, mini caddis pupa shuttlecock, UBDD and LBDDD variants. Maybe spring has at last arrived?
