Flood Warning Issued for Withlacoochee River, FL
• The National Weather Service (NWS) in Tampa Bay Ruskin, FL, has issued a Flood Warning for the Withlacoochee River at US 41 in Dunnellon, affecting Citrus, Levy, and Marion counties. The warning, effective as of September 23, 2026, at 8:33 AM EDT, highlights that the river has been steadily rising since July and reached flood stage on September
• The rise in water levels is attributed to excessive hydrilla growth along a 4.5-mile stretch of the river between US 41 and Lake Rousseau. This vegetation is acting as a natural dam, causing water to back up and levels to increase. Current measurements show the river at 28.2 feet, which is at flood stage, and it is expected to remain at this level for at least the next five days, with potential for further rises.
Impact & Risks
Minor flooding is forecast along the Withlacoochee River, particularly affecting docks and boat ramps in Citrus and Marion counties. At 28.2 feet, the river is at flood stage, which may lead to localized disruptions for residents and businesses near the riverbanks. Historical data indicates this crest matches a previous flood event from October 1979. While the flooding is currently minor, additional rises in water levels could exacerbate impacts in the coming days.
