| dc.description.abstract | Lake Tana, naturally existed reservoir, located in the northern portion of the Abbay river basin is the largest lake in Ethiopia with an average water surface area of 3110 km2 and estimated drainage area of 15340 km2. It is fed by four major tributaries all of them rising in the highlands surrounding the Lake. One regulation weir, Chara-Chara, is constructed at its out let to regulate the lake water for hydropower productions from two existing plants (Tis Abbay I and II) and for the realization of the envisaged development works both in the Tana and Beles Basins. With an estimated mean annual inflow of 12051.5MCM, water resources of the Lake is currently utilized only for hydropower generation at Tis Abbay I & II, local transport from Gondar to Bahir Dar, largely traditional level fishing and for tourist attractions at Tis Esat fall. Recently conducted Abbay river irrigated master plan project studies (BCEOM and associates, 1999) has indicated that the Tana and Beles basins all together have irrigation potential of more than 268,000ha out of which more than 145,000 ha is identified in the upstream reaches of the Lake Tana reservoir. At times of realization of the envisaged development works, irrigation and hydropower development works are, thus, becoming competing demands in the basin. Envisaged development works in the Beles basin are also competing with those in the Tana basin. This situation reveals that planning and reservoir operation in the basin is a serious issue that needs great attention, one of the principal reasons for this research work to be thought. Establishing the water balance of the lake on a monthly time scale is a prerequisite to effect reservoir operation. This activity is performed applying the continuity equation. Final result of the water balance simulation for the lake has shown that 69.2% of the inflow is lost through reservoir losses and 31% lost as an outflow. Currently the reservoir is operated at some operation rule that satisfies the demand from the existing hydropower plants and minimum requirements of the Tis Esat fall. Reservoir operation in this research work is simulated based on deferent envisaged and existing development scenarios that bear different magnitude of demands to the reservoir.
