Excavation of a small lake, some 80m by 35m, in the floodplain across the Nedern Brook from Caldicot Castle, revealed significant prehistoric water-logged deposits; these, investigated from 1988-92, represented various features set within an intercutting sequence of palaeochannels, some of which were dated through radio-carbon: the earliest object was a fragment of plank-sewn boat, dated to about 2,500 BC; this was overlain by an earlier second millennium BC stone & timber platform; the lastest feature was a trackway of about 1,800BC, incorporating much reused material.
