The story behind it
The Lempa is the lifeline of El Salvador. It starts in Guatemala, dips into Honduras and then crosses the whole country from north to west and south, so its water belongs to three states at once. Several dams hold it back, and the wide Suchitlan reservoir behind the Cerron Grande dam makes much of the country's electricity while thousands of water birds rest on its surface. In the hurricane season, from summer to autumn, sudden storms can make the river rise dangerously, and villages near the banks have to be warned. Farmers grow maize, beans and sugar cane in the valley, and fishermen work from small boats. At the mouth the fresh water mixes with the sea among mangroves, where crabs, iguanas and young sea turtles find shelter.
