ABSTRACT

Lago Guerrero, a small reservoir owned by the Puerto Rico Electric Power Authority, is part of the Isabela Hydroelectric System and is located in Aguadilla, in northwestern Puerto Rico. The reservoir had a storage capacity of about 127,376 cubic meters in May 2001 and a maximum depth of about 5.8 meters. Records on dam construction and original topography and storage capacity were not available; therefore, sedimentation rates could not be determined. However, Lago Guerrero resumably was constructed during the 1930’s because it receives water from lago Guajataca, which was constructed in 1928. The May 2001 bathymetric survey of Lago Guerrero established baseline data that are essential to calculate sedimentation rates, sediment yields, storage loss, and sediment deposition sites within the reservoir.
