inspection of the Prinskasteel River
We all met at the Stone Church off Orpen Drive at 09h30. Chris Botes knows the area well and agreed to part lead the way. Peter Reynolds arrived to give a brief back ground of what we were going to inspect.
The concern is the amount of silt and soil landing up in Soetvlei during storms. This is a complex issue as the rainfall runoff and ground water flow starts on TMNP land, enters Buitenverwatching land. Some of the water exits onto PWD (Province land which is under a 99 year lease) then the flow continues downhill onto Uitsig land and then onto City of Cape Town land, before it crosses Orpen Road. The culverts are heavily silted up and do not allow the water to flow under the road in peak flows. The City land has a plantation of poplars which are in the Prinskasteel River course on the western side of Orpen Drive.
Starting off along the road next to the wheat field on the southern border of Uitsig Wine Estate we walked up the sand road, along side the stone lined canal.
