LAKE TAMBLINGAN

+Lake Tamblingan is the smallest of the confined Balinese lakes. It is well sheltered from winds in the caldera, but yet its stratification was not especially strong (RTR 55.2). The lake has an anoxic hypolimnion, but is it meromictic has to verified. The total nitrogen concentrations were from 0.690 to 0.780 mg/l N and total phosphorus concentrations from undetected to 0.002 mg/l P. The carbon dioxide concentrations were from 4.4 to 7.7. 

The lake was seemingly oligotrophic, although the daytime oxygen concentrations showed some oversaturation. The chlorophyll a concentration was 3.77 mg/m³, biomass 0.5 mg/l and transparency 2.7 meters. In the phytoplankton dinophytes, chlorophytes and conjugatophytes were rather evenly represented, but the dominant species was diatom Synedra acus v. angustissima. The state is good although plans for tourist facilities may be a threat. There are plans to develop the area for ecotourism.
