Lake Limboto widely
from year to year and the depth is steadily decreasing. Limboto vast lake in
1999 ranged between 1900-3000 ha, with a depth of 2-4 meters (Fisheries Branch
Gorontalo Regency, 2000). In 1932, the vast waters reached 7,000 ha, with a
maximum depth of 30 m (Sarnita, 1996).
Thus, there has been a
fairly rapid siltation in these waters reaching 38.80 cm / year. Deforestation
around these waters appears to be one of the factors that cause considerable high
silting .Data water quality during 1998-1999 showed that the surface water
temperature of Lake Limboto at noon ranged from 29 to 32.50 ° C, while the
brightness ("transparency ") 35-65 cm. During the day, the oxygen
levels in the surface water and the layer 1 meter below surface respectively 6
to 10.30 mg / l and 4 to 7.10 mg / l.
The content of CO 2 in
the surface layer ranged from 0-5 mg / l, pH 8.30 to 8.80 and total alkalinitasnya
waters ("alkalinity") 55-85 mg CaCO3 / l. Levels of phosphate
compounds ranged from 0.02 to 0.07 mg / l, nitrate content was very small
(close to 0 mg / l), but the level reaches 0.30 to 0.90 nitritnya mg / l, and
organic ingredient content 30 - 37 mg / l. Based on the content of phosphate,
according to the classification of Parma (1980), including the waters of Lake
Limboto mesotrof.
