Bay Walk area, Manila Bay, Manila, Philippines. ( 1 )
Manila Bay is a natural harbour which serves the Port of Manila (on Luzon), in the Philippines. The bay is considered to be one of the best natural harbours in Southeast Asia and one of the finest in the world. Strategically located around the capital city of the Philippines, Manila Bay simplified commerce and trade between the Philippines and its neighbouring countries, becoming the gateway for socio - economic development even before Spanish occupation. With an area of 1,994 km 2 (769.9 sq mi), and a coastline of 190 km ( 118.1 mi ), Manila Bay is situated in the western part of Luzon and is bounded by Cavite and Metro Manila on the east, Bulacan and Pampanga on the north, and Bataan on the west and northwest. Manila Bay drains about 17,000 km 2 ( 6,563.7 sq mi ) of watershed area, with the Pampanga River contributing about 49% of the freshwater influx. With an average depth of 17 m ( 55.8 ft ), it is estimated to have a total volume of 28.9 billion cubic meters ( 28.9 cubic km ). Entrance to the bay is 19 km ( 11.8 mi ) wide and expands to a width of 48 km (29.8 mi). However, width of the bay varies from 22 km ( 13.7 mi ) at its mouth and expanding to 60 km (37.3 mi) at its widest point.
The islands of Corregidor and Caballo divides the entrance into two channels, about two miles ( 3.2 km ) towards the North and 6.5 miles (10.5 km) wide on the South side. Mariveles, in the province of Bataan, is an anchorage just inside the northern entrance and Sangley Point is the former location of Cavite Naval Base. On either side of the bay are volcanic peaks topped with tropical foliage: 40 km to the north is the Bataan Peninsula and to the south is the province of Cavite.
Across the entrance to Manila Bay are several islands, the largest of which is Corregidor, located three kilometres from Bataan and, along with the island of Caballo, separates the mouth of the bay into the North and South Channels. In the south channel is El Fraile Island and outside the entrance, and to the south, is Carabao Island. El Fraile, a rocky island some four acres ( 1.6 ha ) in area, supports the massive concrete and steel ruins of Fort Drum, an island fortress constructed by the United States Army to defend the southern entrance of the bay. To the immediate north and south are additional harbours, on which both local and international ports are situated. Large number of ships at the North and South harbours facilitate maritime activities in the bay. Being smaller of the two harbours, the North Harbour is used for inter-island shipping while the South Harbour is used for large ocean-going vessels.
Manila Bay was connected to Laguna Lake ( or Laguna de Bai) about 3,000 years ago. Recurring episodic uplifts along the West Marikina Valley Fault caused the two to break up. Interaction between Manila Bay and Laguna Lake occurs only through Pasig River.
The bay was the setting for the Battle of Manila Bay in 1898 in which American troops led by Commodore George Dewey, seized the area. Significantly, this battle showcased the United States' naval strength when all major Spanish ships were destroyed and captured. With its proud historic past and the place brimming with marine life, Manila Bay became the ocean portal to its epicentre for government, economy and industry. Seven years later during the Russo-Japanese War at the close of the Battle of Tsushima in 1905, three surviving Russian protected cruisers, the Aurora, Zhemchug, and Oleg, managed to make port in then-United States-controlled Manila for repairs. But because the US was a neutral power, the trio of warships and their crews remained interned by the U.S. until the war officially ended in September that year. In World War II, Corregidor Island was annexed by Japanese forces fighting from this bay once again in 1942. Even earlier various other battles were fought from this naval base including the La Naval de Manila in 1646, which finally put a stop gate to the Dutch trials to seize the Philippines.
Today, Manila Bay remains important for commerce and industry, including fishing, although rapid urban growth and industrialization are contributing to a decline in water quality and deteriorating marine habitats. It also serves a focus for recreation for Metro Manila and is a popular destination for walks and for viewing the sunset. Much of the land fronting the bay along Metro Manila is reclaimed land which now includes important sites such as the Philippine Senate and the Mall of Asia. On September 27, 2011, The sea walls of Manila Bay were destroyed by the storm surge caused by Typhoon Pedring. Even the US Embassy, Museo Pambata and Sofitel Philippine Plaza were submerged into flooding. It was estimated that the damage would cost 30 million peso's. On April 2012, the sea walls were once again opened to public and it was also designed to become stronger to withstand strong storm surges
