Spatial Data for Dam Failure Analysis for the Lago de Guineo dam, Orocovis, Puerto Rico


Publication Date


Gómez-Fragoso, Julieta, and Torres-Sierra, Heriberto, 2016, Spatial Data for Dam failure analysis for the Lago El Guineo Dam, Orocovis, Puerto Rico: U.S. Geological Survey data release,


This data release contains spatial data for the dam failure analysis of Lago de Guineo dam, Orocovis, Puerto Rico. The U.S. Geological Survey, in cooperation with the Puerto Rico Electric Power Authority, completed hydrologic and hydraulic analyses to assess the potential hazard to human life and property associated with the hypothetical failure of the Lago El Guineo Dam. The Lago El Guineo Dam is within the headwaters of the Río Grande de Manatí and impounds a drainage area of about 4.25 square kilometers. The hydrologic assessment was designed to determine the outflow hydrographs and peak discharges for Lago El Guineo and other subbasins in the Río Grande de Manatí hydrographic basin for three extreme rainfall events: (1) a 6-hour [...]

The purpose of this report is to present the results of the hydrologic and hydraulic analyses completed to assess the potential hazards resulting from hypothetical dam failures of the Lago El Guineo Dam under 6- and 24-hour PMP events, a 24-hour 100-year recurrence rainfall event, and sunny-day conditions. The potential hazard at a specific location was defined in terms of (1) maximum river elevation reached at the selected location during the passage of the flood wave, and (2) arrival time after dam failure at the selected location.
