A watching brief was conducted on ground works associated with the erection of flood defences at the Toton Water Treatment works, Toton, Nottinghamshire. All intrusive ground work was monitored during the course of the watching brief. In most instances the ground works did not penetrate below the surface of a sub soil layer and/or were excavated into made ground. The exception was Area 04 where in order to construct a crossing over the River Erewash a section of the river bank was cut through. There were no archaeological features or artefacts revealed as a result of the ground works.
