The River Don in Yorkshire, England, is a remarkable urban and semi-rural fishery that winds through the heart of Sheffield and continues eastward through Rotherham and Doncaster before joining the River Ouse. Once heavily degraded by industrial pollution from Sheffield's steel industry, the Don has undergone one of England's most impressive river recovery stories, transforming from a near-lifeless waterway into a thriving multi-species fishery. The river offers a diverse range of fishing experiences, from fly fishing for wild brown trout in the upper reaches above Sheffield to coarse fishing for barbel, chub, perch, and pike in the middle and lower sections. The completion of a 20-year project to install fish passes at 18 obstructions along the river — including the landmark Masbrough Weir fish pass in Rotherham in 2020 and the Meadowhall fish pass in 2013 — has opened the entire river corridor from the North Sea all the way to Sheffield's spawning grounds, making salmon a genuine and growing prospect on this historically industrial river.
