Abstract: Lake Zeway catchment is located in the northern part of the Central Main Ethiopian rift valley bounded in west and north by Awash basin; and in east by Wabi shebele catchment. Meki and Katar are the main rivers draining western and eastern part of the catchment respectively and both feed Lake Ziway before outflow to Bulbula River in south west. According to the data collected from the National Meteorological Service Agency area has mean annual precipitation, potential evapotranspiration and actual evapotranspiration of 887mm, 1284mm and 856mm respectively. Direct groundwater recharge of the catchment was estimated using soil moisture budgeting method. Groundwater and surface water interaction in the area have been analyzed using groundwater table contour method. The analysis result shows that Meki River in volcanolacustrine deposit of rift floor and Katar River in Upper and Central Wonji Fault Belt are loosing reaches. In the rest of the catchment areas, the rivers and streams are gaining reaches. This facts are important in identifying the reaches which are continuously recharged by the ground water. These reaches are favorable for abstraction because their potential is continuously being recharged. On the other hand for the loosing reaches this information helps us to avoid over abstraction.
