A 7x4m trench was excavated in 2014 in Grange Cottages Wood to a total depth of 2.4m into the western edge of what used to be a pond, This was to establish the original dpeth and profile of the Grange Cottages pond and to ascertain how the pond was established, whether it was once a part of a large pond that had been cut in two by the embankments north of Grange cottages sluice, or whether the pond formed in a pit that had been created when the material was excavated to build the embankments, otherwise known as a 'borrow pit'. The gentle sloping base of the pond was uncovered at an approximate maximum depth of 67.39m OD at the north east corner of the excavation area, however the pond could be deeper towards the centre of the field where no excavations took place. The slope of the base of the pond seemed to be consistent with the bank of the leat to the west of the excavation, which suggests that the pond was excavated so that the material could be used to build up the embankment. This would confirm the pond to have been a borrow pit rather than a larger constructed millpond. This could therefore be an indication that the two features are contemporary with each other. Grange Cottage pond woud have still been a visible feature into the mid 19th century and could potentially still have been retaining water. It is unclear as to whether the pond had already silted up prioer to a large hole being dug to deposit refuse, or whether the material was dumped into the existing depression of the pond. The dateable evidence from these ash and clinker deposits suggest that refuse was no long dumped on the pond site after the mid 20th century.
