Test pit evaluation by R Bradley of Worcestershire Archaeology along the proposed route of a fish pass revealed a series of archaeological deposits forming an alluvial sequence consistent with the location of the site in a waterlogged landscape, adjacent to a managed watercourse. While the dating of the alluvial formation remains uncertain, with the exception of a single prehistoric flint flake, the majority of the diagnostic finds from the test pits related to activity from the mid-18th to early 20th centuries.
Strip, map and record excavation and watching brief by S Westall of AOC revealed a layer of loose, light brown sand, 0.13–0.24m thick, containing a large quantity of worked Mesolithic flints; none were in situ, having been deposited through colluvial or fluvial activity. Two ditches of Roman or possibly medieval date and a Saxon pit were also recorded.
A metal detector survey by T Schofield and M Sommers of Suffolk Archaeology Community Interest Company recovered artefacts including munitions and domestic items within the partially extant buildings of the former Second World War military camp.
