St. Petersburg Launches Bartlett Lake Dredging to Combat Chronic South Side Flooding
The City of St. Petersburg has officially begun dredging operations at Bartlett Lake, marking a critical step in a multi-million dollar effort to protect south St. Pete residents from chronic flooding. Work started on April 23, 2026, as part of a broader strategic initiative to restore the volumetric flow of stormwater from inland basins into Tampa Bay.
The project targets the removal of years of accumulated sediment, muck, and debris that have choked the lakebed, reducing its capacity to hold and move water during heavy rain events. By deepening the lake, city officials aim to prevent stormwater from backing up into the streets and yards of some of the city’s most vulnerable neighborhoods.
The Mechanics of Basin C: Why Dredging Matters
To understand the importance of the Bartlett Lake project, one must seem at the geography of Basin C. This drainage area encompasses 3,535 acres, with much of the land near Lake Maggiore sitting less than three feet above sea level. This low elevation makes the region highly susceptible to both tidal surges and stormwater backups.
The system operates on a gravity-based flow: stormwater drains into Lake Maggiore, moves through Salt Creek, and passes through Bartlett Lake before finally discharging into Tampa Bay. When Bartlett Lake becomes filled with sediment, it acts as a bottleneck, slowing the entire process and leaving neighborhoods like Cromwell Heights, Traditional Southeast, Harbordale, and Bayou Highlands prone to flooding.
“Bartlett Lake, over the years, has gained so much sediment. We necessitate to clean that up given that it doesn’t have the volumetric flow to allow that continuous stormwater to flow out through the system.” Brejesh Prayman, Engineering and Capital Improvements Director
Project Specifications and Funding
The current dredging phase is a precision operation designed to restore the lake’s original functionality. According to city specifications, contractors are removing approximately 23,000 cubic yards of material from a 2.62-acre area. The goal is to reach a design depth of -5 feet Mean Low Water (MLW), with an allowable overdredge to -6 feet MLW.
The dredging initiative carries an approximate cost of $1.5 million and is expected to take roughly 200 days to complete. The project is not being funded by local taxpayers alone; instead, it relies on a combination of federal and state grants:
- Federal Funding: Community Development Block Grant Mitigation (CDBG-MIT) funds.
- State Funding: A Florida Department of Environmental Protection (FDEP) Resilient Florida Grant.
Beyond flood mitigation, the city expects the dredging to improve overall water quality by removing high nutrients, trash and debris
, ensuring that the water discharging into Tampa Bay is cleaner.
A Broader Vision: The St. Pete Agile Resilience Plan
The Bartlett Lake project is not a standalone effort but a component of the St. Pete Agile Resilience Plan (SPAR), championed by Mayor Kenneth Welch. This plan was accelerated in response to the devastating impacts of Hurricanes Helene and Milton in 2024, which exposed critical weaknesses in the city’s stormwater infrastructure.
The broader Basin C initiative represents an approximately $30 million investment. While dredging addresses the storage and flow issues, the city is planning more aggressive infrastructure to combat sea-level rise and tidal influence:
Upcoming Infrastructure Enhancements
- Pump Station: A fresh pump station will be constructed on approximately three acres of land near 4th Street and 18th Avenue South. This station will allow the city to
mitigate the tide as the tide rises and drops
, mechanically pushing water out even when gravity alone is insufficient. - Sluice Gate: The city plans to install a sluice gate to control water flow and protect the system from storm surges that can diminish drainage capacity.
- Salt Creek Widening: Plans include widening sections of Salt Creek to further increase the volume of water that can move toward the bay.
Construction on the pump station is expected to begin later in 2026 and continue through 2028.
Key Takeaways: Bartlett Lake Improvements
- Primary Goal: Reduce chronic flooding in south St. Petersburg by improving stormwater flow to Tampa Bay.
- Volume: Approximately 23,000 cubic yards of sediment will be removed.
- Depth: Target depth is -5 feet Mean Low Water (MLW).
- Cost: $1.5 million for dredging; part of a larger $30 million Basin C investment.
- Timeline: Dredging takes roughly 200 days; pump station construction extends to 2028.
- Drivers: Accelerated by the 2024 hurricane season under the SPAR program.
Frequently Asked Questions
How does dredging a lake stop street flooding?
When a lake fills with silt and muck, it loses its “storage volume.” During a storm, the lake fills up too quickly, and because the outflow is restricted by sediment, the water has nowhere to go but back up into the connected drainage pipes and onto the streets.
Which neighborhoods will benefit most?
The primary beneficiaries are residents in the south St. Pete area, specifically those in Cromwell Heights, Old Southeast, Harbordale, and Bayou Highlands.
Who is paying for these improvements?
The dredging is primarily funded through federal CDBG-MIT funds and the Florida Department of Environmental Protection’s Resilient Florida Grant, minimizing the direct cost to local taxpayers.
As St. Petersburg continues to grapple with rising sea levels and increasingly volatile weather patterns, the transition from passive gravity-based drainage to active, managed systems like the Basin C pump station represents a necessary evolution in urban resilience.
