A small dam is around 15 meters high and 300 meters long

It was built in Adis Nifas in Ethiopia to meet more targeted needs than the Tekeze Dam

It was built by the local community with support from the Relief Society for Tigray which provided machinery and money

The dam is close to the fields and manages to retain water for most of the year even during the dry season

Each family in the village has been given a 1/4 of a hectare of irrigated land, fruit tree seeds and elephant grass to plant in the earth walls to stop them eroding away
