About this water

The Kelvin is Glasgow's urban trout river — the kind of water that the casual visitor walks over without a second glance and the local fly fisher knows intimately. It runs twenty-odd miles from the hills above Kilsyth through Kirkintilloch, Maryhill, and the Botanic Gardens to meet the Clyde under the M8 flyover. For a river that spends most of its lower life threading through housing estates and industrial fringe, it holds an astonishing population of wild brown trout — some of them surprisingly decent fish in the six to twelve ounce range, with the occasional pounder for the angler who knows the good runs. The water recovered remarkably from its industrial past; otters are back, kingfishers nest along the banks, and the trout rise to olives and sedges through the standard Scottish season. The Kelvin Anglers control much of the fishing and issue day tickets. Fish the park water early or late to avoid the dog walkers, work the streamy necks above the old weirs, and keep a low profile — the trout are not stupid, and neither are the cyclists.
