Taiwan's largest natural lake is Sun Moon Lake. Its largest artificial body of water is the Zengwen Reservoir, formed by the Zengwen Dam. The majority of Taiwan's lakes have multiple functions such as irrigation, electricity generation, water supply and tourist attractions. The volume area of natural lakes tend not to be big.
In Chinese language terminology, smaller bodies of water (ponds) are designated the terms ãÂÂæ± ã ("-chi"), ãÂÂå¡ÂãÂÂ("-tang") or ãÂÂæ½ÂãÂÂ("-tan"); larger bodies of water are designated as ãÂÂæ¹ÂãÂÂ("-hu", lake) and ãÂÂæ²¼ãÂÂ("-zhao", marsh); while bodies of water with multiple functions such as irrigation, electricity generation, flood control, etc. are called ãÂÂ水庫ã ("-shuiku", lit. water storage).
