Yesterday I walked from the N7 Highway to the Milnerton Lagoon Mouth to see for myself the challenges facing the Diep River. I was joined by @CityofCT officials. We met community members & user groups along the way.
Along this 15 kilometres stretch of river key challenges we saw were land invasion below the floodline, pollution from industrial run off, and sewage ingress from informal communities.
This morning I will be walking the length of the Lower Diep River to Milnerton Lagoon mouth.
I will see for myself the state of the river & meet community members & officials along the way.
Start: 8AM

The main tributary starts in the Kasteel Mountain, North of Malmesbury. It is joined by the Mosselbank catchment which finds it’s source in Durbanville.
It used to discharge into the ocean at three mouths but now has one fixed mouth at Milnerton Lagoon.

1. Today Deputy Mayor @AndrewsEddie & I helped open the weir at Rondevlei Nature Reserve for the first time since 1998! After a brief boat ride we joined conservation staff in the water to open the sluice gate. 2. This draining of the waterbody simulates the natural draw-down that historically happened in this ecosystem. It will also flush excess nutrients from the waterbody & allow conservation staff to remove invasive Water Hyacinth (Eichhornia crassipes).

Today @CityofCT officials began clearing sludge & bullrushes at Rondevlei Nature Reserve in preparation of the vlei draw-down expected to happen later this week.
Here’s why this is important: 1. Rondevlei (250Ha) is a globally renowned birding site. On an average summer day 70 bird species may be seen. It also home to the #ExtinctintheWild Erica verticillata & Cape Town’s only Hippo pod! 🦛
