The Logiya watershed is part of the Lower Awash River Basin (LARB). The upper part is in the North Wollo Zone of the Amhara Region. Lower down it is in the Afar Region. The Logiya watershed lies to the west of the Awash River, and covers an area of . Elevations range from 384to above sea level. The average altitude is above sea level. Mean annual temperature is in the highest parts and in the lower part.
The watershed is mainly arid lowlands, and has fluctuating temperature and rainfall. Ground cover includes grass steppe, shrub, tree steppe and bare soil with very sparse vegetation. The watershed suffers from severe degradation of the soil and desertification. However, particularly in the upper regions during the periods of high rainfall, it may be subject to flooding.
The main rainy season is from June to September. The dry season is from October to January and the small rainy season is from February to May. Mean annual precipitation varies from in the highlands to in the lowlands.
