Torrential rain in southeast Venezuela has affected 4,500 families and is sending floodwaters gushing through the country's major hydroelectric dam. <br/><br/>Authorities and local media said, the precipitation caused the two main rivers in the country, the Orinoco and the Caroni, to surge over their banks, causing damage in the states of Bolivar, Delta Amacuro and Amazonas. <br/><br/>Local media showed images of flooded houses and streets, and residents trying to save furniture from the water. They also showed video of water gushing through Venezuela's Guri hydroelectric dam, which provides 70 percent of electricity for the country.
