Laguna de Apoyo (Lake Apoyo) is Nicaragua's largest volcanic crater lake. It was formed 23,000 years ago after a huge volcanic explosion left a large crater which interrupted the underground water table. Today, the lake is 180 meters deep and four kilometers in diameter. Its clear water is always warm, never below 28 degrees Celsius (great for swimming!). In Nicaragua, the term "laguna" is given to the volcanic crater lakes which are found in some of the volcanoes along the Pacific region of the country.

Laguna de Apoyo and the crater in which is it located were named the Laguna de Apoyo Nature Reserve as an official protected area in 1991, by Decreto 42-91 in the National Assembly. However, until recently, this site has never enjoyed the full benefits of protection that would be afforded this designation. Estación Biológica Laguna de Apoyo worked closely with the another Nicaraguan organization, Liga de Cooperativas de Nicaragua (CLUSA), in the development of its first management plan., commissioned and approved by the Nicaraguan Ministry of Natural Resources and the Environment. FUNDECI/GAIA directed biodiversity studies and coordinated consensus-building activities with the various interest groups involved as part of the management plan development, and developed a set of 35 maps demarcating the reserve boundaries, land use patterns, risk assessments, wildlife, and tourism potential.

Lake Apoyo is a special place, not only for its amazing views from near and far. The water of Lake Apoyo is home for six endemic species of cichlid fishes. The research group of Estación Biológica Laguna de Apoyo discovered five of these species, and we are continuing research on the evolutionary history, ecology, and conservation aspects of these fishes.

The chancho cichlid, Amphilophus chancho, was discovered officially by the research team coordinated by FUNDECI/GAIA in 2008. Here is a male in breeding coloration in its natural habitat. Lake Apoyo is the only habitat for six species of cichlids including this one. Photo Ad Konings.

Laguna de Apoyo is facing severe threats to its continued existence as a beautiful, natural lake. Although Laguna de Apoyo Nature Reserve is located between two of the most populous cities in Nicaragua (Masaya and Granada), the reserve continues to contain substantial quantities of natural forest and a huge lake in very good condition. Nonetheless, housing developments, trash, deforestation, and invasive species all threaten Lake Apoyo and its special inhabitants.
