The rapids and cascades of Dominican streams are pregnant with possibilities, but up to the present time they have remained in their pristine condition, nor is their energy utilized to drive a single piece of machinery. The largest and most beautiful waterfall of the island is doubtless that of the Jimenoa River, in the mountains some ten miles south of the city of La Vega, where the Jimenoa rushes over a precipice one hundred feet in height, producing clouds of spray and a roar that can sometimes be perceived as far as Jarabacoa, six miles away. Another beautiful fall is that of the Dajabon River, on the Haitian frontier, 30 feet in height, and there are notable cascades also on the Comate River, near Bayaguana, on the great plains; on the Nigua and Higuero Rivers, not many miles from Santo Domingo City; on the Inova River, near the town of San Jose de las Matas; and on the Guaranas River, on the Haitian frontier in the commune of Neiba. The only lakes of any size are two which lie in the Neiba Valley, the larger one, Lake Enriquillo, being comprised entirely within Dominican territory, while of the smaller one, variously called Etang Saumatre, or Lake Azuei, or Laguna del Fondo, through which the frontier line passes, less than one-fourth is under Dominican jurisdiction. They are both very picturesque, and with the greenish color of their water and their arid mountain surroundings recall portions of Lake Titicaca in Bolivia. In stormy weather they become as rough as the ocean. Lake Enriquillo derives its name from the last Indian cacique of the Island, the romantic chieftain Enriquillo, who after fiercely resisting the Spaniards finally in 1533 concluded an honorable peace with them on the island of Cabras in the center of this lake. The lake is over 70 miles in circumference, having a length of about 33 miles and a width ranging from 3 to 9 miles, Cabras Island, 6 miles long by one in width, is the home of herds of goats. Lake Azuei is but 15 miles in length with a width of from 2 to 7 miles. Though the two lakes are scarcely five miles apart, Lake Enriquillo is 102 feet below and Lake Azuei 56 feet above sea-level. Both lakes receive the waters of several small fresh water creeks, yet they apparently have no outlet and their water is salt, that of Lake Azuei only slightly, but that of Lake Enriquillo more so than the sea. On Cabras Island, however, there is a fresh water spring, and three lagoons to the east and south of Lake Enriquillo also contain fresh water. Lake Azuei often shows the paradox of going down during the rainy season and rising during the dry season; the phenomenon is attributed to the presence of springs at the bottom of the lake, which are unusually copious at the end of the rainy season. Both lakes have at least one variety of ocean fish, though the nearest point of the seacoast is some twenty miles distant; turtles abound in both and there are many alligators in Lake Enriquillo and a few in Lake Azuei.
