Annotation
An unconsolidated coastal aquifer near Lady Barron on Flinders Island is confined by a partly cemented iron-stained B soil horizon. Analysis of drawdowns in seven observation bores monitoring a fourteen day pump test showed that T is in the range 68-105 square metres per day, S is probably about 5 x 10-3 and that the data required correction for barometric fluctuations. The barometric efficiency of the aquifer is about 0.50. The existing array of bores will easily supply the township with 230 cubic metres per day. The water will need to be treated.
