"Mean annual runoff in the
Sabie-Sand Catchment is approximately 762 million cubic metres. Flows in
the Sabie River peak in summer, and low flows are experienced at the end
of the winter dry season, although no-flow conditions have never been
recorded."(www.csir.co.za/rhp/state_of_rivers/state_of_crocsabieolif_01/sabie_eco.html)

"This ecoregion covers the upper
section of the Drakensberg Escarpment, with altitudes between 1 000 and
2 000 m above mean sea level, and high mountainous relief. As a
consequence of the range in altitude and relief, there is a large
variation in rainfall (600-1 200 mm per year) and mean annual
temperature (10-18°C)." (www.csir.co.za/rhp/state_of_rivers/state_of_crocsabieolif_01/sabie_eco.html)

The headwaters of the Sabie River and its
tributaries (the Sand, Marite, Mutlumuvi, Motitsi and Mac Mac Rivers)
arise in the upper parts of the escarpment. These rivers are cold
mountain streams, narrow with moderate to steep gradients, and hence
fast flowing. Waterfalls are common, and rocky pools and rapids
abound." (www.csir.co.za/rhp/state_of_rivers/state_of_crocsabieolif_01/sabie_eco.html)
