How long is the Castlereagh River in New South Wales?
Castlereagh River
The below-ground sedimentary deposits in the area of the Great Artesian Basin are particularly good water stores (aquifers), and the highly permeable sediments below NSW’s western flowing rivers create excellent aquifers.[17] A theory of an extensive sub-artesian store of water was proposed by Mr James Samuels and published in the "Empire" of 27 and 28 August 1868, including a view that dry inland rivers would have water under the bed. Some pastoralists in western NSW paid attention and began to sink wells, often near rivers.[18] This may have contributed to the idea of an underground flowing river in the largely empty above-ground Castlereagh.
