The U.S. Geological Survey, in cooperation with the Puerto Rico Electric Power Authority, conducted a sedimentation survey of Lago Guayabal in 2017 to determine reservoir infill sedimentation rates, generate a bathymetric map of the bottom elevations of the reservoir, and create a stage-volume relation. The original (1913) capacity of Lago Guayabal was 11.82 million cubic meters, and efforts to increase the storage capacity were made in 1950 by the installation of flashboards. The 2017 survey indicated that storage capacity of Lago Guayabal is 4.98 million cubic meters. The estimated full sediment infill of Lago Guayabal is expected in 77 years, based on the long-term sedimentation rate of 0.065 million cubic meters per year determined for the 1972–2017 period.
