The Tampa Bypass Canal and Palm River are a 14-mile-long (23 km) flood bypass operated by the Southwest Florida Water Management District. The canal includes several concrete flood control structures and was constructed during the 1960s and 1970s. Its purpose is to redirect flood waters from large amounts of rainfall from the Hillsborough River to Tampa Bay to prevent floodwaters reaching homes and businesses. Despite its original purpose it is now used as a drinking water source for the City of Tampa. During construction of the canal the Floridan aquifer was accidentally breached.
