It lies within the municipalities of Valencia, Sibulan, and San Jose in the province of Negros Oriental.[2][3] GeographyThe lakes are situated northwest of a narrow mountain ridge, in a caldera formed by four mountains: Mount Mahungot to the south, Mount Kalbasan to the north, Mount Balinsasayao to the east and Guintabon Dome to the west.[4] A normal fault separates Lakes Balinsasayao and Danao while and another fault, the Amlan, is about {{convert|1,400|m}} west of Danao. Four geologic faults also intersect the southern edge of Lake Danao, whose water level is lower than that of Balinsasayao.[5] Flora and faunaAs a protected natural park home to an expansive ecosystem and biodiversity, Balinsasayao Twin Lakes National Park is one of the major tourist attractions in Negros Oriental.[4] The lake has a rich fish fauna and the surrounding dipterocarp forests are rich in bird life. However, invasive fish species such as tilapia, common carp, mudfish, shrimp, mosquito fish and milkfish have been introduced in the lake.[6][7] TourismThe Department of Environment and Natural Resources (DENR) through the Biodiversity Management Bureau (BMB) manages tourist activities in the natural park. The bureau allows swimming, sightseeing, mountain trekking, camping, birdwatching, paddle boating in Lake Balinsasayao. The natural park has a concrete view deck, umbrella cottages, a restaurant, a souvenir shop, restrooms, and a visitor center.[8] ConservationConserving the natural park's flora and fauna is a continuing struggle as surrounding forests are exploited for timber and charcoal production. The uncontrolled cutting of timber by slash-and-burn farmers or kaingineros is reducing the inflow of water to the lakes and causing a fall in water levels. Also, since the lakes are situated near Energy Development Corporation (EDC)'s Southern Negros Geothermal Field in Valencia, the forest surrounding the lakes are under threat from constant geothermal drilling. A co-management plan for geothermal preservation has been drafted by the DENR-PENRO, EDC, and the local governments of Valencia and Sibulan.[9][10] See also
