Iloilo City is located in the southern shores of Panay Island. The city faces Iloilo Strait and Guimaras Island across it, making it a natural harbor and a safe anchorage for ships. The city lies on a flat alluvial plain, reclaimed mostly from the swampy areas due to urbanization and industrialization in the late 19th century until the present. Traversing the city are the rivers of Iloilo, Batiano, Jaro and Dungon Creek. Iloilo River is an estuary that separates the districts of City Proper, Molo and Villa Arevalo from the rest of the city. On the other hand, Jaro River is fed by its tributary rivers, Aganan and Tigum. Lately a new escape channel for floodwaters coming from these two rivers to Iloilo Straight was developed, the Jaro Floodway. Iloilo City is 337.6 nautical miles from Manila. The city has a total land area of 70.3 square kilometres (27.1 sq mi).
