The watching brief monitored the excavation of two trial pits, located to the south of Bourton-on-the-Water Sewage Treatment Works and to the north of Rissington Road. No archaeological features or deposits were exposed during the watching brief. The stratigraphic sequence revealed layers of alluvium beneath the topsoil, with a peat deposit and river terrace gravels exposed within trial pit 1. Blue grey clay was observed in trial pit 2 which was possibly the top of the natural geology or an earlier alluvial deposit.
