In the southwest of Sri Lanka, in the Sabaragamuwa Province, is a river known as the Kukuleganga River. Along the river is the Kukule Ganga Dam and reservoir. This river, which has a basin area of 31,000 ha (120 sq. m), an average annual rainfall of 3,800 mm (150 in), and an annual water yield of 976,000 ha/m (735,000 acre/ft.), is used to power the Kukule Ganga Dam. The Kukulegaga River meanders through verdant, lush environments, its waters reflecting the sun's rays. Its banks are dotted with tall, swaying trees that create dappled shadows on the glistening water below.
