The lake was originally much larger than it is today. Seven large permanent rivers feed the lake as well as 40 small seasonal rivers. The main tributaries to the lake are Gilgel Abbay (Little Nile River), and the Megech, Gumara, and Rib rivers.
Lake Tana has a number of islands, whose number varies depending on the level of the lake. It has fallen about in the last 400 years. According to

Water characteristics and floods
Compared to other tropical lakes, the waters in Lake Tana are relatively cold, typically ranging from about . The water has a
pH that is neutral to somewhat
alkaline and its transparency is quite low.
Because of the large seasonal variations in the inflow of its tributaries, rain and evaporation, the water levels of Lake Tana typically vary by in a year, peaking in September–October just after the main wet season. When the water levels are high, the plains around the lake often are flooded and other permanent swamps in the region become connected to the lake.
