NSW Groundwater Database (Water Data Transfer Format and Hydstra)

Abstract

This dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.

Hydstra Water Levels 9-6-12

The Hydstra data for NSW Office of Water (NoW) was extracted on 9 June 2012 although the latest water level reading date is April 2012. The Hydstra groundwater database was provided by NoW and was imported into MS Access from the HYDMEAS database file (dbf).

The Hydstra database stores groundwater level information from \~ 11,800 bores. This includes the NSW monitoring network of bores and private bores (eg. Stock bores with a water level reading).

Site information on the bores has not been included as this data is available from the NoW NGIS. The NGIS has been quality checked and should be used for all site data.

The Hydstra data should only be used for bores that are not included in the WDTF.

Of the 4000 extra bores in hydstra, many water level readings have been taken at the time of drilling and many are once off readings. These data have not been validated.

Any information obtained from the Hydstra data should be assessed for its quality prior to inclusion in a Bioregional Assessment.

There is no data dictionary that came with the hydstra data. Groundwater levels are variable 110.

Variable 110 = Depth to groundwater from the measurement point. The measurement point can then be derived from the NGIS which will have an elevation Field = TSRefElev.

Wdtf NoW 19-11-12

Through the Water Regulations, a full extract of NSW monitoring data was provided in WDTF in November 2012, although the latest water level reading date is September 2012.

WDTF was provided for \~7,800 monitoring bores across NSW. This data was extracted from the original WDTF using python scripts, into the MS Access database.

Site information on the bores has not been included as this data is available from the NoW NGIS. The NGIS has been quality checked and should be used for all site data.

The WDTF is provided to the Bureau by NoW as "Validated" data. Therefore, WDTF should be used as the primary source for groundwater level data.
