The Tame pollution also reached the Trent as well, with one of the worse affected reaches being that downstream of the confluence with the Tame through Burton, this being exacerbated by its late introduction of sewage treatment, and the substantial wastewater arising from the breweries in the town. Angling clubs in Burton used the Dove or local lakes for fishing, as the Trent through the town was absent of any fish. Downstream, the inflow of cleaner water from the Dove and then the Derwent meant that conditions improved enough to allow recreational coarse fishing in the lower reaches.
