Twelve test pits were dug between December 2005 and April 2006. Each test pit was 1m2 and was excavated to the top of the mudstone. Mercia mudstones were encountered in the base of each test pit and in some cases there was evidence to suggest the material had been redeposited. The lack of evidence for water deposited material, swan mussel shells, indeed the overall lack of molluscan material raises the unexpected possibility that the leats and ponds were regularly emptied and cleaned out.
