Tampa Bay is a large natural harbor and shallow estuary connected to the Gulf of Mexico on the west-central coast of Florida , comprising Hillsborough Bay, McKay Bay , Old Tampa Bay, Middle Tampa Bay, and Lower Tampa Bay. The largest freshwater inflow into the bay is the Hillsborough River , which flows into Hillsborough Bay in downtown Tampa . Many other smaller rivers and streams also flow into Tampa Bay, resulting in a large watershed area .
53-505: Safety Harbor is a city on the west shore of Tampa Bay in Pinellas County , Florida , United States. It was settled in 1823 and incorporated in 1917. The population was 17,072 at the 2020 census. The area has been inhabited since the Stone Age . In June 2008, a 6,000-year-old spearhead was found at Marshall Street Park. The inhabitants of the area at the time of Spanish exploration were
106-514: A leak of 65 million gallons of acidic water from a Cargill phosphate plant on the bay's southern shore severely impacted wetlands in the vicinity of the spill. And in April 2021, a breach of a wastewater reservoir at the long-closed Piney Point phosphate plant sent over 200 millions gallons of nutrient-rich mine tailings streaming into lower Tampa Bay. The resulting growth of red tide algae led to an ecocide and killed over 1000 tons of fish in

Safety Harbor sites have yielded pottery, and artifacts of copper, shell, and stone. The Tocobaga were known for constructing various ceremonial and communal mounds to bury the dead. Most of these mounds were destroyed in the early 1900s due to development. However, one of these ceremonial mounds

Once ships reached this area of the bay, all threats from pirates were gone, and it was commonly referred to as a "Safe Harbor". Safety Harbor is the home of the historic Espiritu Santo Springs, or "Springs of the Holy Spirit", a natural mineral spring . Its waters were given this name in 1539 by
742-403: The 1950s. However, industrial and agricultural runoff along with runoff from developed areas pose a continuing threat to marine ecosystems in the bay, particularly by clouding the water with sediments and algae blooms, and seagrass coverage declined slightly in the late 2010s. Wastewater pollution from old phosphate plants near the shoreline has been a particular problem. For example, in 2004,
795-472: The 20th century. Today, the area is home to about 4 million residents, making Tampa Bay a heavily used commercial and recreational waterway and subjecting it to increasing amounts of pollutants from industry, agriculture, sewage, and surface runoff . The bay's water quality was seriously degraded by the early 1980s, resulting in a sharp decline in sea life and decreased availability for recreational use. Greater care has been taken in recent decades to mitigate
848-593: The Bay, including St. Petersburg and Tampa are adapting infrastructure and buildings to face changes in sea level. Humans have lived in Florida for millennia, at least 14,000 years. Due to worldwide glaciation, sea levels were much lower at the time, and Florida's peninsula extended almost 60 miles west of today's coastline. Paleo-Indian sites have been found near rivers and lakes in northern Florida, leading to speculation that these first Floridians also lived on Tampa Bay when it
901-595: The Corps of Engineers dredged another channel from the mouth of Tampa Bay to the Port of Tampa, instantly making the city an important shipping center. The Corps of Engineers currently maintains more than 80 miles of deep-water channels in Tampa Bay up to a depth of 47 feet. These must be continuously re-dredged and deepened due to the sandy nature of the bay bottom. While dredging has enabled seaborne commerce to become an important part of
954-513: The Floridian leg of the Trail of Tears . For the next 100 years, many new communities were founded around the bay. Fort Brooke begat Tampa on the northeast shore, Fort Harrison (a minor military outpost on Florida's west coast) begat Clearwater , the trading post of "Braden's Town" developed into Bradenton on the south, and St. Petersburg grew quickly after its founding in the late 19th century, on

Prior to the Spanish exploration of Florida, the Tocobaga and Timuquan tribes are believed to have fished and bathed in the spring's waters. In the 20th century, Espiritu Santo water was bottled and sold commercially, and later a health spa and hotel were built over the springs. The Safety Harbor Resort and Spa, as it

Dredged material has also been used to create several spoil islands on the eastern side of Hillsboro Bay. These islands have become important nesting sites for many seabirds, including threatened species such as oystercatchers , and have been designated as "sanctuary islands" that are off-limits to boaters.

The effects of Hurricane Milton in October 2024 caused polluted waste from the fertilizer industry including products from Mosaic , which were retained after the production of phosphate, to enter into Tampa Bay. Both Hurricane Milton and Hurricane Helene caused disruption in the production of phosphate fertilizers from Tampa Bay. Tampa Bay, like other parts of Florida ,
1378-427: The bay created a connection between the lake and the gulf. Tampa Bay is Florida's largest open-water estuary, extending over 400 square miles (1,000 km ) and forming coastlines of Hillsborough , Manatee and Pinellas counties. The freshwater sources of the bay are distributed among over a hundred small tributaries, rather than a single river. The Hillsborough River is the largest such freshwater source, with
1431-503: The bay was connected to the Gulf of Mexico. This culture, which relied almost exclusively on the bay for food and other resources, was in turn replaced by the similar Safety Harbor culture by approximately 800 AD. The pre-contact Indigenous nation most associated with the Tampa Bay are the historic Tocobaga nation, who are known to be among the ancestors of the contemporary Seminole and Miccosukee Tribes of Florida. The Safety Harbor culture
1484-433: The bay. Not finding gold or silver in the vicinity and unable to convert the native inhabitants to Christianity, the Spanish did not remain in the Tampa Bay area for long. However, diseases they introduced decimated the native population over the ensuing decades, leading to the near-total collapse of every established culture across peninsular Florida. Between this depopulation and the indifference of its colonial owners,

Beginning in the early 1980s after federal and state legislation to improve water quality, authorities installed improved water treatment plants and tightened regulation of industrial discharge , leading to slow but steady improvement in water quality and general ecological health. By 2010, measures of sea grass coverage, water clarity, and biodiversity had improved to levels last seen in
1590-470: The city of Tampa's downtown wharves on Hillsboro Bay. Most ships would anchor well out from shore and transfer cargo and passengers to and from the city in smaller boats. Henry B. Plant 's railroad line reached the area in 1884 and ran across the Interbay Peninsula to Old Tampa Bay, where he built the town and shipping facility of Port Tampa at its terminus. In 1898, Plant used his connections in

The racial makeup of the city is 92.23% White , 4.14% African American , 0.24% Native American , 1.68% Asian , 0.05% Pacific Islander , 0.44% from other races, and 1.21% from two or more races. 3.65% of the population are Hispanic or Latino of any race. As of 2000, there were 7,084 households, out of which 28.8% had children under
1749-399: The clearing of mangroves for shoreline development were important factors. Most damaging was the discharge of waste water and other pollutants into the bay, which drastically degraded water quality. The bay's health reached a low point in the 1970s. The water was so murky that sunlight could not reach the shallow bottom, reducing sea grass coverage by more than 80% compared to earlier in

The indigenous population had been decimated by disease and warfare by the late 1600s, and there were no permanent human settlements in the area for over a century. The United States took possession of Florida in 1821 and established Fort Brooke at the mouth of the Hillsborough River in 1824. The communities surrounding Tampa Bay grew tremendously during
1855-408: The early 20th century, traveling overland between the growing communities around Tampa Bay was an arduous process. The trip between Tampa and St. Petersburg was almost 50 miles (80 km) around the north end of Old Tampa Bay and took up to 12 hours by train and over a full day over uncertain roads by car. The trip between St. Petersburg and Bradenton was even longer – over 70 miles (110 km) all

Most of the islands (including several man-made islands built from dredge spoil ) and sandbars are off-limits to the public, due to their fragile ecology and their use as nesting sites by many species of birds. The Tampa Bay Estuary Program keeps watch over the Bay's health. Tampa Bay was once teeming with fish and wildlife. People of the Safety Harbor culture lived almost entirely from mullet, shellfish, sea turtles, manatees, crabs, and other bounties harvested from

The establishment and rapid growth of surrounding communities during the 20th century caused serious damage to the bay's natural environment. Heavy harvesting of fish and other sea life, constant dredging of shipping channels, and

The difficulty of traveling between Tampa and St. Petersburg in the early 20th century inspired the world's first scheduled air service, the St. Petersburg-Tampa Airboat Line , which operated during the tourist season of 1914. While the construction of bridges made air travel across Tampa Bay unnecessary, several airports have been built along

In 1924, the Gandy Bridge over Old Tampa Bay reduced the driving distance between Tampa and St. Petersburg to 19 miles (31 km). Ten years later, the Davis Causeway (later renamed the Courtney Campbell Causeway ) was built between Clearwater and Tampa. More bridges criss-crossed Tampa Bay over the ensuing decades, making travel between

As Tampa began to grow in the mid-1800s, roads across central Florida were still just rough trails and rail lines did not yet extend down the Florida peninsula, so the most convenient means of traveling to and from the area was by sea. By the late 19th century, however, the shallow nature of Tampa Bay made it impossible for large modern vessels with deeper drafts to reach
