A river interrupted

5/4/2015

What kind of stories do rivers tell? These living water systems are always changing, but they carry the marks of history on their banks. On 27 March I had the chance to follow the Diep River from close to its source, to where it opens into the Little Princess Vlei. This trip was organised by various partners involved in the Source to Sea project, which is exploring integrated and proactive ways to manage river corridors, and is looking at  creating a trail along the Diep River as part of this project.
   Once, this water system was connected to Princess Vlei and the othervleis in the area through an extensive network of seasonal watercourses and wetlands, but as the map below shows, these water flows have been interrupted by human activity. Humans have had much impact on the course of this river, as my journey revealed.
   The Diep River forms a thin, unbroken blue line on this map, but following it is not as straightforward as it looks here.

The river


Picture
1  The river originates on the mountain and runs through Cecilia Forest in a beautiful stream

2 It flows through  the Constantia Green Belt, alongside the Alphen trail. We joined it opposite the Alphen Hotel, which has been owned by the Cloete family for generations. Alex and Nicky Cloete-Hopkins told us how the river used to drive a water wheel at a small mill, which can be seen here. Successive flooding led to them creating stone gabions  to hold the river banks.

3 It offers a restful refuge to passers by, before going under the 4 lane M3 high way.

Picture
4 Although it is only a few kilometers from its source there is evidence of pollution, as it meanders through lower Constantia behind Norman Henshilwood School.
Picture
6 Water is taken from the river to irrigate the school fields
Picture
5 This black elder tree is one of many invasive alien species that have taken root by the river.
Picture
7 Clearing litter is a constant problem, but can also provide employment as it does for these workers for the EPWP.
Picture
8 The winter rains and storm water off the streets create floods which erode the river banks and wash away infrastructure, like this wall.
Picture
10 The residents with houses also create problems. Garden waste dumped in or next to the river clogs up litter and silt traps
Picture
12 Our city is full of boundaries, but a river knows no fences ...
Picture
14 It goes through some private gardens ...
Picture
16 Here it joins the Wynberg River, and is crossed by the oldest bridge on Main Rd. It wearily carries much of the waste tossed into street gutters and storm drains.
Picture
18  Soon the river has to duck under a railway line
Picture
20  The river disappears from view under the factories in the Diep River industrial area - the only sign of it is in the name of this building. 
Picture
22 The high Spanish reeds are aliens, but they can be harvested for ceilings and garden fences.
 
Picture
9 Everyone wants a home by the river ... but these informal residents can create pollution and litter problems.
Picture
11 The gardens of the wealthy also bring in many exotic aliens, which disrupt the river flow and indigenous flora
Picture
13 We find our river friend again wandering besides this children's play structure ...
Picture
15 And comes out again, no longer meandering through the earth but held by the concrete walls of a canal
Picture
17 Here, the two joined rivers are split - the original canal proved inadequate for winter floods, so instead of widening it they build another alongside it.
Picture
19  One of the many storm water drains challenging the river's ecosystem.
Picture
21  The river seems to sigh with relief as at last it leaves behind its concrete walls, and the two streams are reunited.
Picture
23 The river is chocked with other aliens, but biological control agents with species such as water hyacinth and Parrots Feather, are making a difference. Despite the pollution and alien infestation, the river still provides a home to bird species such as this Red-knobbed Coot
Picture
24 At last we reach the shores of the Little Princess - the waters will move through here, and then onto Zandvlei. The Little Princess Vlei's  big sister lies a few hundred meters away, separated by sand dunes. Perhaps one day, these two sisters will be united again, and the water system will be restored to make a beautiful trail from Source to Sea.

Rivers are actually a very important part of our evolution. If you are not familiar with this knowledge, then you should read this very carefully. Well, for starters, there are a lot of things that make rivers very important to our development. First, rivers provide a great source of food and water, which is very important to humans. This is why human civilization is often found near rivers. Second, rivers are there to keep most natural disasters away from us.
