April Rainfall

April’s low rainfall highlights need for water conservation


April marks the third consecutive month of below-average rainfall for the St. Johns River Water Management District’s 18-county region. While frontal systems brought some rain, it primarily benefited the northern counties, leaving the southern counties drier. Overall, six counties experienced above-average rainfall, while 12 were below.

Despite the dry conditions, groundwater levels districtwide remain well above drought indicator levels, with most areas within the normal range. District staff continue to monitor rainfall and groundwater levels to ensure adequate supply for public demand.

While it is always critical to use our water wisely, the District strongly encourages the public to be mindful of their water usage during these dry months until our summer rainfall patterns return.

Below are simple tips for residents and businesses to help save water and money on their water bill. 


  • Only run washing machines and dishwashers with full loads.
  • Use the shortest washing cycle for lightly soiled clothes.
  • Thaw frozen food in the refrigerator or microwave, not under running water.
  • Scrape dishes instead of rinsing before loading into the dishwasher.
  • Install high-efficiency showerheads, faucets and toilets.


  • Check and repair leaks in irrigation systems.
  • Turn off irrigation systems and water only as needed.
  • Use a kitchen timer to avoid overwatering with sprinklers.
  • Use a hose with a shut-off nozzle when washing cars.
  • Install a rain barrel with a drip irrigation system for landscaping; rainwater is free and better for plants.

A full report outlining April’s hydrologic conditions was presented at the District’s Governing Board meeting Tuesday. Highlights include:


  • Districtwide average rainfall was 2.14 inches, 0.47 inches below the monthly average.
