Following Hurricane Milton, the Southwest Florida Water Management District (District) has deactivated the Tampa Bypass Canal System and the Hillsborough Flood Detention Area (HFDA), as water levels in the Hillsborough River have returned to normal. This marks a positive step as the region recovers from the heavy rainfall caused by the storm.
To assist with flood control during the storm, the District activated the Tampa Bypass Canal System on October 8 to protect Temple Terrace and Tampa from potential flooding. Now, with water levels declining, the District has reopened Structure S-155, located north of Morris Bridge Road and east of I-75, which can be seen from the interstate. The removal of the boat barriers earlier today has restored safe navigation along the Hillsborough River.
A Brief History of the Tampa Bypass Canal System
The Tampa Bypass Canal System was constructed in response to severe flooding from Hurricane Donna in 1960. The system has been vital in protecting the area from future floods, especially during hurricane season. It consists of three key components:
- Lower Hillsborough Flood Detention Area (LHFDA) – A reservoir that captures floodwaters from the Hillsborough River and its surrounding 450-square-mile watershed.
- Tampa Bypass Canal – A 15.7-mile-long canal equipped with five flood control structures to manage water flow.
- Harney Canal – A critical piece that helps channel the water from the Tampa Bypass Canal to McKay Bay.
When the Hillsborough River floods, the system impounds the excess water into the 16,000-acre HFDA. From there, water is released into the Tampa Bypass Canal, which diverts the flows safely away from populated areas, protecting Temple Terrace and Tampa from potential flood damage.
Beyond Flood Protection
While the primary role of the Tampa Bypass Canal is flood control, it also serves an important secondary purpose: providing a source of drinking water for the Tampa Bay area. This dual-purpose system demonstrates the District's commitment to water management and community safety.

The District’s proactive approach ensures that residents remain protected from flooding, while also addressing water supply needs, making the Tampa Bypass Canal System an essential asset to the Tampa Bay region.
