The purpose of the dam is to provide water for irrigation and municipal uses and to generate hydroelectric power.

The dam withholds a reservoir of 286,000,000 m3 (232,000 acre⋅ft) and the power station, located near its base, has an installed capacity of 43 MW.

Near the southern end of the reservoir is Jibacoa Dam, an auxiliary dam, which closes off one valley to create the existing large reservoir.
