The government ordered an in depth investigation into the possible causes of the death of thousands of fish in the Hatillo Dam. Samples of the affected waters and fish have been sent to the Marine Biology and Chemistry Departments of the Universidad Autonoma de Santo Domingo, the state university. A greasy stain is suspect of causing the poisoning of the waters of the 50 square kilometer artificial lake that with its 8,000 million gallons of water is considered the largest reservoir of non-salted water in the Caribbean.
