The Historical Environment  Assessment was unable to be undertaken , as normally would  be  expected, due to the excavation of the pond , before work could be carried out. Any Historical Artefacts would have been lost. The Valley was first formed in the ice age by a melting Glacier, which created its steep sides. It was occupied by Bronze Age man,  with evidence of his occupation such as the Cornish Hedges, which in themselves are protected by legislation as are all hedges. These were farming people at this time and these Cornish hedges are still delineating the fields they were originally intended for. Nearby is a small field which has had several flint tools found, giving the suggestion that there was a Flint Knappers Site in the Vicinty. 

Adjacent to the Pond, just a few yards across the stream , is the Adit for Kelynack Mine. This was a small ancient tin mine which last produced Black Tin in 1901.  When the pond was excavated no testing was carried out for the leaching of harmful chemicals from the mine. No structural Engineering Assessment was made at the time of excavations  to assert  the strength and stability of the soil banks. Should they burst and flood into the adit, there is a possibility that contaminated waters could be washed into the stream. Causing irreparable damage to the wildlife , aquatics, and vegetation.

When the Stream was originally Dammed to fill the pond , the level of  was so low, and with the Dam in place,  fish and  Elvers (young eels) were unable to head upstream to spawn. The sediment from the banks started to silt the stream when construction began, and has continued to this day especially with the heavy rainfall we have experienced.Even with the Dam removed as instructed by the Lead  Flood Authority, water was still extracted without permission to keep the pond filled. If this was a natural feature in the base of the Valley it would not need extraction from the stream.
