| 06 Jun 2001 | Have spoken to Mr White informing him of the likelihood of min flow conditions being placed on his groundwater consent application. |
| 07 Jan 2002 | well depth amended from 10 to 8m as per consultant Clare Glandville |
| 22 Feb 2002 | Driller drawdown test. Initial WL -0.25. 1 min 0.5, 5 mins 1.2, 10mins 1.7, 30 mins 1.8, 60 mins 2, 120mins 2.15, 300 mins 2.5, 720 mins 3m, 16 hours 3m. |
| 25 Aug 2005 | Gridref changed from: K37:0677-8628. This well can be artesian with approximately an inch of rain. There is a spring very close to well, pumping from well will dry up spring. |
| 04 Mar 2014 | bore not used - no infrastructure - temporary waiver application in place |
| 10 Jan 2023 | Reference Level updated using LiDAR imagery in Dec 2022. The existing RL was 45.14 and the QAR RL was 4. The method of calculating the original RL was: Interpolated DTM. If GL from MP is updated in future please assess if RL also needs to be updated. |
| 09 Feb 2023 | Locality updated from Half Chain Road to Flemington as part of Wells DB QA update |
| 10 May 2023 | Dec 2022 Reference Level update using LiDAR was in NZVD 2016, rather than Lyttelton 1937. Rectified in May 2023 by using the previously determined LiDAR elevation value and LINZ conversion tool to calculate Lyttelton 1937 elevation and update Reference Level field. Reference Level updated from 45.086m to 45.443m. |
