Dhadimagi Kilhi (literally "Dhadimagu Lake") is one of the two fresh water lakes in Fuvahmulah, Maldives.
Located in Dhadimagu ward of the island, with an area of 6.37 hectares and an average depth of 4 feet, it is the second-largest lake by volume in the Maldives, and larger in area than its counterpart Bandaara Kilhi, which is the largest lake by volume in the country. Bounded by dense vegetation of different kinds ranging from ferns to reeds used for weaving mats, taro fields and plant varieties such as Syzygium cumini (jambul), pond-apple, mango, pineapple, screwpine, tropical almond, cheese fruit, ambarella and banana fields as well, there is the continuation of a large marsh land area towards the south of the island associated with the lake.
In the past, fish were farmed and harvested in the lake. Dhadimagi Kilhi is frequented by anglers who game for tilapia fish and visitors who enjoy boat riding and feeding the fish which inhabit the lake. Among the birds which inhabit the place apart from the common moorhen which is a bird exclusively found in Fuvahmulah only in the Maldivian archipelago, Maldivian white-breasted waterhen (Amaurornis phoenicurus maldivus) which is an endemic species of the Maldives too can be sighted by the lakeside. Among seasonal visitors are flamingos, herons and white terns.
