So how much rain do we need to feed the rivers and creeks?
Is there any data or any way to know with out having to see it in person?
Cheers
River heights can provide a estimate of surounding creek/waterway levels. (within the catchment)
for example.
http://www.bom.gov.au/fwo/IDN60233/IDN6 ... .tbl.shtmlShows the Cox river at Kelpie point is currently (25th Feb) at 0.07m.
It was at 0.18m on the 21st so the river level is dropping again after the rain on the 20-22nd. I checked previously on the 17th (before the rains) and the river level was at 0.02m.
So you can see the table is a fair indication of the impact of significant rain in the area and its impact on nearby river/creek systems.
You do have to be careful of catchment boundaries etc. eg Dex creek feeds into Ti Willia Creek, which feeds into the Kowmung which eventually feeds into the Cox but just below kelpie point. So the Cox river gauge at Kelpie is not capturing water that is coming from Dex, Ti Willia and the Kowmung but from catchments further upstream. Dex creek is 9.5km as the crow flys from Kelpie Point. Also the Cox river catchment is huge whereas Dex creek catchment is tiny by comparison.
As far as im aware there is no river gauge (or weather station) that captures the Dex, Ti Willia creeks to give an accurate estimate. Personally I wouldnt be counting on water at Dex or 100 man cave until there is a first hand report from after the rains.
