Well or borehole construction
The well was originally sunk for a household water supply, and subsequently adopted as an observation well after a period of disuse. The well is 0.84 metres in diameter and 31.33 metres deep.
Hydrograph response
The hydrograph has an annual sinusoidal appearance. Annual fluctuations are normally around 10 metres, but as high as 25 metres in some exceptional years. The extreme limits of its fluctuation are constrained by the well construction; with water nearing ground level in wet years and the well effectively drying up in the driest years.
Data issues
Logger installed.
