IRC repair project in 2003 went back as far as the front of large rock on the right of the picture. In 2014, in addition to removing 11 years of detritus which had refilled the reservoir, the town extended excavation to where I am standing with Saa Kaimondo (centre distance)
We had dscussed using bushsticks to retain the earth bank and slow down further incursion, but the towns people decided this would be temporary, bush sticks would rot quickly and disintegrate, we also discussed planting deep rooted grasses or water reeds. In the end the townspeople voted on using a barrier of locally available rocks to be gathered from nearby.
