Flow rates update

hi guys,

Online flow rate data is not accurate at the moment:
The Rand Water site is out of date http://www.randwater.co.za/Education/Edu_Details.asp?ArticleId=48
and the DWAF site is registering erroneous flows at the Goose Bay sensor and no data for the Schoemansdrif sensor http://www.dwaf.gov.za/Hydrology/rtmain.aspx

In winter it is generally safe to take a flow rate reading from the next sensor upstream which in this case is the Vaal outflow sensor currently reading 12m^3/s and add a few tons for water entering at the barrage to arrive at an estimated flow of between 15 and 20 m^3/s.

hope this helps,
keith
