This well monitors water levels in the Chalk of Wessex.
It is dug into the Lewes Nodular Chalk Formation. The site lies on the south side of the west-north-west–east-south-east trending Winterbourne Abbas Fault with a downthrow to the north-north-east of 20 m.
It is a brick lined well, 1.4 metres in diameter. It was originally sunk for a farm water supply.
The hydrograph has an annual sinusoidal appearance, with some response to intense winter rainfall events. Its response is rapid for a chalk well, presumably because of its shallow depth. It appears to have an unconstrained response, although levels tend to peak close to 71 m AOD, and have only been lower than 64 metres on rare occasions.
