Effective water conservation

Michael Dreyer, Plumstead

Well done Table Mountain National Park staff.

Wire box gabions filled with stone and erected across eroding streams have raised the groundwater level by metres. That is effective water conservation benefiting many – and in addition, reversing the erosion of the river bed.

In one place above such a gabion there are still pools of water. The pools are evidence of the groundwater level in this place. The water level is about two metres higher than without a gabion dam wall.

And this raised water level is achieved at the end of a second year of drought. Well done.

There is also a slow discharge of water below this gabion “dam.” And for this source of water all the wild life must be extremely grateful.
