YAHUECAS DAM

This dam is located in the Central part of Puerto Rico a 4 miles to the northwest of the town of Adjuntas, near the Castaņer town. The lake is formed by a monolithic concrete dam of 90 feet of height on the Blanco River, a tributary one of the Grande de Aņasco River. The capacity of the dam is of 267 acre-feet until the elevation of the crest. The Yahuecas Lake is connected to the Guayo Lake by a derivation tunnel. This causes that its normal level corresponds to the elevation of the crest of the Guayo dam (1460 feet). The drainage area is 17.4 miles square.

The construction of Dam completed in 1956 by the old Authority of the Fluvial Sources (PREPA). Form leaves from the project of the Southwest of Puerto Rico for the hydroelectric generation and the irrigation of the Valley of Lajas. This project of multiple uses has two main lakes to dam its waters (Guayo and Lucchetti) and others of smaller dam. It is generated in the Yauco I and Yauco II plants and the water dams up in the Loco Lake.
