What is well yield?
Well yield is how much water a well can supply over time. It depends on the aquifer, the depth and construction of the well, the pump and how much you draw. Yield can shift with the seasons and across wet and dry years.
A well that has always been reliable can still struggle in prolonged drought, especially if it is shallow or if neighbors are also pumping heavily.
Well construction also matters. Older and shallower wells are generally more sensitive to dry conditions. A licensed professional can tell you more about your own well from records and inspection.
What are warning signs?
Watch for sputtering faucets, reduced pressure, cloudy or sandy water, a pump that runs longer or cycles more often, and a change in taste or smell. Any of these can have causes other than drought, so they are worth investigating.
If the water changes in appearance or smell, do not assume it is safe to drink. Contact your county health department about testing.
Think about neighbors too. If several wells in an area struggle at once, local officials may need to know, and shared solutions such as hauling or temporary connections may open up.
- Sputtering or low pressure
- Pump running longer than usual
- Cloudy, sandy or odd-smelling water
- Water that runs out at the same time each day
How can I use less water during drought?
Reduce nonessential use first: spread out laundry, fix leaks, shorten showers, limit outdoor watering and delay car washing. Check that livestock waterers and float valves are not leaking or overflowing.
Spread demand across the day so the well can recover between uses. If animals depend on the well, make a plan for how much water they need and where you could get more if the supply drops. Ask your Extension service for guidance.
If you are a livestock producer, count your animals' needs first, since they may use far more water than the household. Hauling water or connecting to another source may become necessary, and planning before a crisis matters.
Who should I call for help?
If you suspect a well problem, call a licensed well driller or pump contractor in your state. They can check water level, pump condition and the well itself. Do not lower pumps or alter equipment without expertise.
Your county health department can advise on testing, and your state agency in charge of groundwater or drinking water may have drought guidance. The EPA private wells site and university Extension pages explain well care and drought steps.
Keep the written receipt and report from any service call. A history of work done on your well helps the next professional diagnose problems faster.
What should I know about water quality after drought?
When water levels fall and then recover, water quality can change. Sediment may stir up, and contaminants can become more concentrated or be flushed in by heavy rain. After a drought breaks or after flooding, consider having your well water tested.
Ask the county health department which tests are appropriate for your area. Do not rely on appearance alone.
Remember that stress and worry about water are normal. Talking with neighbors, family or local agencies can lighten the load, and you do not have to solve it alone.
How can I prepare before the next dry spell?
Know the depth and age of your well if records exist, and keep the driller's report. Keep a simple log of pump run times or water use. Consider storage for emergencies, and have a plan for hauling water.
Keep contact information for your well professional, county health department and utility in one place. Check Drought.gov for current conditions in your area.
What if my well runs dry?
Stay calm and stop running the pump if it is clearly drawing air, because running a pump dry can damage it. Switch to your emergency water supply and contact a licensed well professional as soon as you can.
Ask your county health department or emergency management office about emergency water sources and help in your area. Bottled water, hauled water and temporary connections are all options, and rules differ by place.
Look after people first: drinking, cooking, medications and hygiene come before landscaping and cleaning. Check on elderly or ill neighbors who may also be affected, and let local officials know if many wells in your area are failing.
- Stop the pump if it is pulling air
- Call a licensed professional
- Use emergency water for essentials
- Check on neighbors
Key takeaways
- Well yield can fall in prolonged drought, especially in shallow wells.
- Watch for pressure changes, cloudy water and a pump running longer.
- Cut nonessential water use and spread demand through the day.
- Call a licensed well professional and your county health department for help.
