Gabions built across eroding streams have raised the groundwater level by metres.
That is effective water conservation benefiting many and has also reversed 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 2m 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 wildlife must be extremely grateful.
