O'Hares Creek - the Woolwash - Georges River catchment |
|
These photographs were taken on the 15 May 2010 prior to the heavy rain we received on the catchment one week later. There was no water flow from O'Hares Creek and Stokes Creek catchments which supply by far the greatest volume of water to Georges River from the Woronora Plateau. Some have estimated it to be as high as 70% This location is now the main monitoring location for the Georges River catchment. Downstream we have the Basin with the influx of water from the pristine Punchbowl Creek, a minor tributary of Georges River which is not affected by longwall mining yet. BHP Billiton Illawarra Coal have included Punchbowl Creeks headwaters in their 30 year Bulli Coal Seam project. |

O'Hares Creek has consistently shown very low water levels and almost no water flow throughout 2010 . We saw similar results in 2009 which was a very high rainfall year with the highest levels of rainfall recorded for ten years. We saw Georges River in Flood during June 2010 yet prior to June O'Hares Creek had no water flow for long periods of time. On the 10 July we once again see the water level drop 280 millimeters in O'Hares Creek despite being in a wet period and still receiving rain in Macarthur. |
