Galveston Bay is a large estuary located along Texas's coastline. The bay is formed from the confluence of the Trinity River and the San Jacinto River, combined with the incoming tides from the Gulf of Mexico. The bay covers approximately 600 square miles (1,500 km˛), and is 30 miles (50 km) long and 17 miles (27 km) wide. Galveston Bay is only 7-9 feet (3 m) deep. The bay drains through a channel between Galveston Island and the Bolivar Peninsula.
Galveston is the county seat of Galveston County located along the Gulf Coast region in the U.S. state of Texas within the Houston–Sugar Land–Baytown metropolitan area.
Galveston is accessible by a causeway linking Galveston Island to the mainland on the north end of the city, a toll bridge on the western end of the island, and by ferry boat service on the east end of the city.
In 1839, the City of Galveston adopted a charter and was incorporated by the Congress of the Republic of Texas.
