Lake Tana ( Amharic : ጣና ሐይቅ , romanized :  T’ana ḥāyik’i ; previously transcribed Tsana ) is the largest lake in Ethiopia and a source of the Blue Nile . Located in Amhara Region in the north-western Ethiopian Highlands , the lake is approximately 84 kilometres (52 miles) long and 66 kilometres (41 miles) wide, with a maximum depth of 15 metres (49 feet), and an elevation of 1,788 metres (5,866 feet). Lake Tana is fed by the Gilgel Abay , Reb and Gumara rivers. Its surface area ranges from 3,000 to 3,500 square kilometres (1,200 to 1,400 square miles), depending on season and rainfall. The lake level has been regulated since the construction of the control weir where the lake discharges into the Blue Nile. This controls the flow to the Blue Nile Falls (Tis Abbai) and hydro-power station.
