The falls are estimated to be between 37 and 45 meters high, consisting of four streams that originally varied from a trickle in the dry season to over 400 meters wide in the rainy season. Regulation of Lake Tana now reduces the variation somewhat, and since 2003 a hydro-electric station has taken much of the flow out of the falls except during the rainy season.
A short distance downstream from the falls sits the first stone bridge constructed in Ethiopia, built at the command of Emperor Susenyos in 1626. According to Manuel de Almeida, stone for making lime had been found nearby along the tributary Alata, and a craftsman who had come from India with Afonso Mendes, the Catholic Patriarch of Ethiopia, supervised the construction.
