the flowing of this rift with water. The length of Lake Uluabat which is mainly
fed by the Mustafakemalpaşa River is 25 kilometers in east-west direction, the
width is 14 kilometers on the widest part, the acreage is 156 square kilometers
and the depth is average 2,4 meters and maximum 4 meters.

Through this feature, Lake Uluabat has been taken under protection in 1998 within the RAMSAR Wetlands Convention. Being a very valuable wetland connected to “Living Lakes Chain”, Lake Uluabat provides nutrition and sheltering to hundreds of types of creatures through available climate conditions, large reed beds, open water surface and nutrient potential.
The Lake Uluabat is also has a very rich variety of species in terms of fishery. In the lake many species such as carp, pike, crayfish, silver pond fish, vimba alburnus, roach, rutilus rutilus, tinca tinca, grey mullet, catfish, broad-nosed pipefish, bitterling and monkey goby are living.

Reaching today from the ‘Mesozoic Age’ when the earth crust began breaking apart with faults and disintegrating to separate continents, Ayvaini Cave, was discovered by a team of 3 Spaniards back in 1970.
Groundwater springs from the Ayva Village mouth of the cave which is hydrologically active. In the cave, which is almost 5,5 kilometers long, there are 60 lagoons of 3-4 meters long, and the length of the lagoon at the exit of the cave is about 400 meters. The water level changes according to seasonal effects.
Ayvaini Cave, which is a real natural beauty with fantastic stalactites and stalagmites, wall drip stones, aqueous drip stone ponds and lagoons and untouched nature, is a haunt especially for speleologists and mountaineers.
