The second most important watershed is the Caribbean Sea. The rivers of this region are usually short and of scarce and irregular flow, with some exceptions such as the Catatumbo, which originates in Colombia and drains into the Maracaibo Lake basin. Among the rivers that reach the Maracaibo lake basin are the Chama, the Escalante, the Catatumbo, and the contributions of the smaller basins of the Tocuyo, Yaracuy, Neverí and Manzanares rivers.
