South Florida’s Drier Than Normal Wet Season
What It Means for Groundwater, Canals, and Private Wells in the District
Overview
South Florida’s 2025 wet season delivered below average rainfall across much of the region. As a result, Palm Beach County transitioned into the dry season with lower groundwater and surface-water levels than usual for this time of year. According to drought monitor data, portions of Palm Beach County are already experiencing abnormally dry or drought conditions.
The District’s canals not only provide drainage to mitigate flooding during the wet season but also hold water during the dry season to ensure adequate water supply and to help recharge groundwater. For a community that relies on shallow private wells, understanding these conditions helps residents anticipate seasonal impacts and make informed decisions about water use.
Rainfall This Year: A Quick Summary
- Rainfall totals across eastern South Florida were several inches below normal.
- Some monitoring stations saw one of the driest mid-season periods on record.
- Afternoon thunderstorm activity, the primary source of groundwater recharge, was less frequent and less widespread.
- Portions of our region entered October with ongoing drought classifications.
These conditions mean the usual “recharge window” for the surficial aquifer was weaker than normal.
Why This Matters for Our Community
Groundwater Levels
Lower rainfall leads to reduced recharge of the surficial aquifer, which many District residents depend on for:
- Private potable wells
- Irrigation wells
- Small-diameter agricultural wells
When the wet season underperforms, groundwater levels may be several inches to several feet lower than historical norms at the start of the dry season.
Canal System Conditions
The District’s canal network helps regulate water levels, protect private property, and support overall drainage. A drier wet season may result in:
- Lower starting canal elevations heading into the dry months
- Faster declines during extended dry spells
- Reduced lateral support to shallow groundwater near canal banks
While the District maintains its operating ranges year-round, natural inputs play a substantial role in seasonal water balance.
Potential Impacts on Private Wells
Reduced Well Output
Shallow wells (commonly 20–30 feet in our area) are sensitive to seasonal groundwater fluctuations. Lower aquifer levels can cause:
- Reduced water volume during peak irrigation times
- Occasional drawdown if multiple wells in the area are pumping simultaneously
Water Quality Changes
When groundwater levels drop, residents may notice:
- Temporary cloudiness or sediment
- Increases in minerals, iron, or hardness
- Air intrusion if levels approach the pump intake
Equipment Strain
Frequent cycling or running dry can stress pumps and pressure systems. Monitoring output early in the dry season helps prevent avoidable repairs.
How Residents Can Help
- Observe Year-Round Water Restrictions: The South Florida Water Management District’s year-round landscape watering restrictions (Chapter 40E-24, Florida Administrative Code) are designed to ensure the efficient use of water landscape (includes lawns) irrigation.
- Check for home water inefficiencies: Repair leaky hoses, spigots, toilets, and irrigation lines to prevent unnecessary loss during the driest months.
- Practice efficient car washing: Use shut-off nozzles, minimize runoff, or consider commercial car washes that recycle water.
- Be mindful of landscape choices: Drought-tolerant plants, mulching, and proper mowing heights help reduce irrigation demand.
- Plan for seasonal changes: Expect lower natural water availability through spring; adjust outdoor water habits accordingly.
- Stay informed: Follow District updates on rainfall, canal conditions, and dry-season advisories to help guide household practices.
District Commitment
The South Indian River Water Control District remains focused on responsible water-level management, drainage operations, and educational outreach to landowners. Seasonal variability is normal in South Florida, but this year’s drier-than-average wet season underscores the importance of staying informed about its effects on wells and local water resources.
