Hanabanilla Reservoir

Hanabanilla Reservoir. It is a significant artificial lake located in the central region of Cuba, nestled within the northern slopes of the Escambray Mountains. Created by the damming of the Hanabanilla River, its primary purposes are hydroelectric power generation, water supply for agriculture, and tourism. The reservoir is a key feature in the hydrology of Villa Clara Province and is surrounded by the protected landscapes of Topes de Collantes.

Geography and location

The reservoir is situated in the mountainous terrain of the Guamuhaya Massif, part of the larger Escambray Mountains range. It lies within the municipality of Manicaragua in Villa Clara Province, near the provincial border with Cienfuegos Province and Sancti Spíritus Province. The main inflows are the Hanabanilla River and the Jibacoa River, which drain a catchment area characterized by dense tropical forests and steep valleys. Its waters eventually flow out via the Hanabanilla River towards the Agabama River system, contributing to the wider Zaza River basin. The surrounding area is part of the Topes de Collantes Natural Park, a region known for its biodiversity and ecotourism.

History and construction

The construction of the Hanabanilla Dam was initiated as part of broader national development efforts following the Cuban Revolution. The project was designed and built with technical assistance, reflecting the period's economic partnerships. The dam was completed and the reservoir impounded in 1972, creating one of the largest artificial lakes in central Cuba. Its creation involved significant engineering work to manage the flow of the Hanabanilla River in a geologically complex area. The development was aligned with the goals of the National Institute of Water Resources to increase the country's hydroelectric capacity and water security.

Technical specifications

The Hanabanilla Dam is an embankment dam constructed using local materials. The reservoir has a total surface area of approximately 14.6 square kilometers and a maximum storage capacity of 285 million cubic meters. The normal operating water level is around 364 meters above mean sea level. The installed hydroelectric power station, known as the Hanabanilla Hydroelectric Plant, has a generating capacity of 43.2 megawatts, contributing to the national grid managed by Unión Eléctrica de Cuba. The dam's spillway and outlet works are designed to manage inflows from the mountainous catchment, which experiences high rainfall, particularly during the Atlantic hurricane season.

Ecological and environmental aspects

The reservoir and its watershed are located within an area of high ecological value, adjacent to the protected areas of Topes de Collantes. The region is part of the Cuban moist forests ecoregion and hosts numerous endemic species, including various birds like the Cuban trogon and plants such as the Cuban pine. Water quality is monitored due to its importance for drinking water and aquatic life. Environmental considerations include managing sedimentation from the upstream rivers and preserving the riparian zones to maintain habitat for native fauna, including populations of Cuban gar and freshwater shrimp.

Economic and social importance

Hanabanilla Reservoir is a cornerstone for regional water resource management, supplying irrigation for agricultural areas in Villa Clara Province, including crops like tobacco and citrus. Its hydroelectric plant provides a renewable source of energy for the central provinces, supporting the infrastructure of Unión Eléctrica de Cuba. The reservoir is also a focal point for tourism, with the Hanabanilla Hotel located on its shores offering access to fishing, boating, and hiking in the Escambray Mountains. It plays a vital role in the local economy of Manicaragua and is integral to water supply plans for communities and industries in the region.
