Aba Gerima Observatory

Aba Gerima watershed is found in Amhara region, West Gojam zone, Bahir Dar Zuria Woreda specifically in Aba Gerima Gonibat Kebele. It is situated about 15km from Bahir Dar city. The head of the watershed, at its southern part, can be accessed through a road that goes from Zenzelima to Awunhara Monestry, where the boundary touches the road to the north off-ramp at a small village called Aba Dama. Aba Gerima watershed is bounded by two kebeles namely, Gonibat Abagerima to the north and North west and Laguna Abune Hana to the south and south west, but majority of the watershed is found in Gonibat Abagerima kebele. Abagerima watershed covers around 900ha of land. Aba Gerima watershed represents peculiar landscape of the Woreda that looks like plain but when looked very closely, it has rolling scenery. The watershed is part of the Tana sub- basin located nearby Lake Tana. It is a representative landscape of the northern part of Abay basin particularly Lake Tana surroundings. Heterogeneity in landscape is highly observed in the watershed as a result diverse land use systems and land cover types are commonly observed in the watershed most of the watershed is severely degraded by sheet erosion.
