From the St. Johns River Water Management District
Rainfall in June was below average for the fifth consecutive month across the St. Johns River Water Management District’s 18-county region. Invest 90L brought much-needed rainfall mid-month, followed by increased thunderstorm precipitation during the last week of June, especially benefiting the southern region of the District. Even with the extra rainfall at the end of the month, most of the District is experiencing abnormally dry conditions, according to the U.S. Drought Monitor.
Rainfall continued to be scarce and unevenly distributed in June, with 14 counties receiving less than their monthly average. In some areas, the deficit was more than two inches, with Baker County receiving 4.5 inches below normal.
District staff continue to monitor rainfall and groundwater levels to ensure adequate supply for public demand but emphasize the importance of using 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.
Indoor
- 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.
Outdoor
- 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.
