Siniloan River

The Siniloan River (Tagalog: Ilog ng Siniloan), also known as the Romelo River, is a river system that runs through Siniloan, Laguna on the island of Luzon, in the Philippines. It is one of 21 tributaries of Laguna de Bay and is regularly monitored by the Laguna Lake Development Authority (LLDA) through one of its 15 river monitoring stations. The river's headwaters can be found in the Sierra Madre Mountain Range, particularly Mount Romelo for which the river is often alternately named. In this part of the river, a number of falls have become popular destinations amongst mountaineers, with a reputation for clear waters and a reasonably easy trek. The river then heads down into the coastal plains, going through the main population area of the municipality of Siniloan before finally emptying into Laguna de Bay. Throughout its watershed, from mountains to lowlands, the Siniloan is dominated by coconut and grasses. The mountain areas are also characterized by forests, while the lowlands are also characterized by rice paddies and residential areas. The Siniloan River sub-basin has a drainage area of 74.31 square kilometres (28.69 sq mi).
