The River Torne is a lowland river flowing through South Yorkshire and North Lincolnshire in northern England, rising at the Upper Lake at Sandbeck Hall near Maltby and traveling northeastward through the heavily drained landscape of Hatfield Chase before emptying into the River Trent at Keadby pumping station. The river is distinctively engineered — extensively modified, straightened, and deepened over centuries to serve agricultural drainage and flood prevention across the Isle of Axholme. This engineering history gives the Torne a character quite different from natural chalk streams or upland rivers; it is a working drainage channel as much as a river, with limited natural habitat complexity in many stretches. Despite this, the Torne and its surrounding catchment support a surprisingly rich coarse fishery, making it a worthwhile destination for anglers targeting a variety of species in a flat, open landscape.
