other birds, are seen in an island in the lake, it is also known as "Stork Island", and another island in the lake where large number of goats has been named as 'Goat Island'. Legend Nui Coc Lake is the subject of a legend about 'Coc', a boy from a poor family, and 'Cong', a girl from a rich mandarin family. Despite being deeply in love with each other, Coc was not allowed to marry Cong due to the difference in their social status. Despondent, broken-hearted and pining for his lover, Coc played the flute to call Cong to his room, but she was not allowed to leave the house to meet him. Coc eventually died, whereupon fairies took pity on him and transformed him into Coc Mountain, which now surrounds the lake. When Cong heard of her lover's fate, she began to cry, day and night. Her love was sincere and loyal, and she cried so much that it resulted in her dying and transforming into tears, which seeped to the ground and started flowing as a stream called the 'Cong River' (which feeds the lake) in search of her fiancé. During the summer season every year violet sim (rose myrtle) flowers bloom in the Coc mountain hill and the Nui Coc Lake. The legend is also extended to the province, which is named as Tan Cuong. Further, it is said that the famous Tan Cuong tea grown here has absorbed Cong's tears in its roots created the sweet flavor of the tea. Uses The lake waters have been put to several beneficial uses. These are for: Irrigation The lake was initially conceived for irrigation, in 1977. The reservoir storage provides for irrigation through a canal system for of wetland cultivation. Apart from recreational activities, the reservoir is also used for aqua culture. Fish production is reported to be per year. Nui Coc lake and hydropower The lake waters are used for hydropower generation at a small power station with 3 units of 630 KW capacity each, on a canal head of an irrigation canal that takes off from the reservoir. The energy generation is about 2 MWh. The irrigation system was built in 1977. However, the power plant construction on the irrigation canal was started in Jan 2008 and the plant commissioned in Jan 2010. A 22 kV transmission line evacuates the power generated to a nearby grid.
