Black Lake, Idaho
Black Lake, Idaho is located south of the
Coeur d'Alene River and its
outlet discharges into the river. The lake has experienced
severe cyanobacterial blooms, that reportedly killed
livestock and pets that drank from the lake. J. Eilers supervised a paleolimnolgical
study of the lake to determine if the lake
had changed and, if so, when the change occurred. The results indicate that
the lake has experienced a considerable increase in sediment accumulation rate
in the 20th century and substantial increases in phosphorus in the
upper sediments. Further analyses of the sediments may be pursued to determine
when the cyanobacteria became abundant and to examine other indicators of
changes in water quality.
