It is a large lake, covering an area of between 135 and 160 km2 depending on the water level, but very shallow, being only 3 m deep at its deepest point.

Water leaves the lake by way of the Ulubat stream, flowing to the west, and reaches the Sea of Marmara via the Susurluk River.

[2] Most shores of the lake are covered in submerged plants, and it has the most extensive white water lily beds in Turkey.

According to the Global Nature Fund, there is nowhere in Turkey with more white water lily beds than Lake Uluabat.

The orthodox monastery has received attention from scholars because of its inscribed cross type with apses east and west.

[6] One of the most well-known features of Lake Uluabat is the small island village of Gölyazı—an ancient Greek settlement near modern-day Bursa.
