The lake was created from 1937 until it was completed in 1942 with the construction of the Dos Bocas Dam, by the Puerto Rico Electric Power Authority for a hydroelectric power plant.

In recent years, silt has accumulated in the lake causing capacity to shrink.

Silt has also made some portions of the land inaccessible by boat.

Other nearby attractions include the Río Abajo State Forest.
