The Old River Mooki Channel – Implications for Open-cast Mining at Watermark

Groundwater level monitoring data recovered at the end of 2019 from Mystery Road at Breeza on the Liverpool Plains reveals a direct connection between the Gunnedah Formation unconsolidated sands and gravels and the underlying Permian coal measures.  The connection is provided by the old deep channel of the Mooki River that cuts down into the coal measures. This is a crucial piece of evidence to be incorporated into groundwater models.
