Located in the middle Satonda including Dompu region , NTB . This lake has unique because the water is salty as sea water . It is estimated that the lake water is salty because it is saturated with seawater overflowed and trapped in the lake when Mount Tambora erupted ( similar to the lake Kakaban ) . This is possible because the distance Satonda with Mount Tambora is very close and is known as an eruption
Tambora eruption of very heavy so it may cause a tidal wave ( tsunami ) that powerful anyway .

Lake Satonda

Lake Satonda

Satonda vast lake approximately 2.5 km2 and is not known to exist in the type of habitat in this lake because the research has not been done .

Distance from Samawa Seaside Cottages toward Lake Satonda about 60 minutes research by boat.


Two European scientists , Stephan Kempe and Josef Kazmierczak , pioneering research at the lake . They first visited the lake when the Dutch Indonesian Satonda Snell II Expedition in November 1984 , and then returned to research in 1989 and 1996 .

For both, Satonda is a rare phenomenon because of the salty water with alkalinity ( alkalinity level ) is very high compared with sea water generally . They then try to reconstruct the history of the formation of the lake and its ecosystem .

Kempe and Kazmierczak pour some of the results of their research in an article titled Microbialites and Hydrochemistry of the Crater Lake of Satonda , 1996 . Both argue , Satonda basin coincided with the formation of a crater more than 10,000 years ago .

Originally , it contained a freshwater lake , which is evidenced from peat deposits beneath the sea minerals in sediments resemble the edge of the lake . The lake was then flooded with sea water that seeps through the cracks of the crater wall collapsed . At that time , sea levels 1 meter – 1 , 5 meters higher than today.

However , sea level is slowly shrinking . Screening of sea water through the walls of the crater was slowed . Now , the water level of the lake is relatively stable , which marks no longer relationship with the sea water .

The presence of stromatolites in Satonda be very interesting because it shows these lakes have an environment that resembles an ancient ocean , Precambrian . Stromatolites in the modern world only found in water with very high salinity . Satonda for scientists to be a model that reflects the contemporary environmental conditions in ancient oceans .

During its development , Kempe and Kazmierczak wrote , rain makes the water surface of the lake becomes more bargaining . Another suggestion which leads to reduced salinity surface water of the lake is the eruption of Tambora in 1815 .

Tambora eruption has destroyed forests in Satonda . The lack of trees leads to reduced evaporation , too much rain water collected in the crater . It causes the upper layers of water become more fresh . At the same time , some of the water that is older and more depressed salted down or out of the lake through the pores of volcanic rocks open .
