Excavation by NEHHAS adjacent to the course of a Second World War anti-tank ditch. No report or details of the results have been submitted.

Evaluation by Bryan Matthews of OA in advance of residential redevelopment exposed a number of features of Roman and prehistoric date, together with a 19th/20th century horse burial. The subsequent excavation is reported on elsewhere (SyAC 91, 187–216).

Observation of the excavation of a series of test pits by R Poulton of SCAU in advance of proposals to create a road crossing over the Epsom to Waterloo railway revealed evidence of extensive modern development.

Investigation by J and P Wardle and M Rubra of SyAS. A series of chalk and flint footings discovered by the owner, which appeared to be the remains of a fairly recent structure probably removed in the early 1960s, were examined. The property lies on the route of the GCHQ Stop Line, although there was no conclusive evidence for a military connection to the structure. (394)

Excavation by M Borrell and G Stonehouse of SyAS to attempt to locate an 18th century icehouse demolished together with Wonersh House in 1929. The work revealed substantial modern building debris, but no structural features.

Evaluation by M Dover of SCAU prior to residential development on the former playing fields. Only one feature (a probable wall foundation) of potential interest was revealed, although this was probably modern. The majority of the site had been disturbed previously by the creation of level surfaces for the playing fields.

Archaeological monitoring programme conducted by A Brossler of OA of c 11km of pipeline trenching. Only a single pit of likely Bronze Age date was noted to be of interest, with a number of additional features found to be of modern date.Archaeological monitoring programme conducted by A Brossler of OA of c 11km of pipeline trenching.

Repair works involving the cutting of a slit trench for a short distance along the dam starting at the south edge of the sluice. The work was monitored by D Graham and D Attryde of SyAS. No finds were recovered, but the west section of the trench was recorded.

Photographic recording by T Howe of SCC during remedial works. Parts of the reinforcing iron superstructure of the wall had become dangerous through erosion to the concrete fabric and ongoing military use of the site. These were removed for health and safety reasons, with a basic record compiled to add to the SMR. Military use of the site has since ceased in order to protect the historic fabric and wider ecological balance of the feature and its surrounding landscape.
