• Fisio-Ecological Conditions
According to Schmidt & Ferguson entered in the classification of climate types A and the value of Q = 9.75% and rainfall from 4000 to 4727 mm / year. The amount of rainfall is affecting the situation of the lake ecosystem, where field conditions are lowlands with hollows will be under water when the rainy season arrived with into between 6 - 14 m and a dry field when the season arrives.
Approximately nine months of the year, the lakes in this region almost always stagnant water and in July-August, a puddle of water on these lakes began to decline and then become dry land with only a small river that flows around the lake .
