Standing water in your yard after rain: what causes it and how to fix it

Sources (7)

Short answer: If the yard dries out within a day or two of a storm, that's normal. Puddles that last several days usually come from low spots (grading) or soil that water can't soak into (compaction or heavy clay). Water that never goes away points to high groundwater or a leak.That's the Northern Virginia Soil & Water Conservation District's rule of thumb (NVSWCD).

Checked October 18, 2026. This is general guidance from Extension and conservation-district pages. Drainage that pushes water toward a neighbor or a foundation is a job for a professional, and many counties have rules about it.

Step 1: Figure out which kind of wet you have

What you see	Likely cause	Source
Dries within 1–2 days after rain	Normal, no fix needed	NVSWCD
Puddles or soggy patches for several days after storms	Low spots or depressions, or poor infiltration from compacted soil, heavy clay or shallow bedrock	NVSWCD
Wet for months, or all the time	Naturally high groundwater (low ground, floodplains, springs), or a leaking pipe, sprinkler line, faucet or pool	NVSWCD
Water stands in a 2-foot hole within 2–3 hours of digging	High water table	VCE 430-026

Step 2: Do a 24-hour drainage test

University of Maryland Extension's quick perc test: dig a hole 12 inches deep and 12 inches across, fill it with water, and refill it the next day. All of the water should be gone within eight hours. Less than 1 inch per hour is too slow and may mean compaction, a lot of clay, buried debris, a high water table or a restrictive layer. More than 4 inches per hour is very sandy soil (UMD Extension). Virginia Cooperative Extension uses the same benchmark: about one inch per hour is a well-drained soil (VCE 430-026).

Before you dig, look up your soil's mapped drainage class for free on the USDA NRCS Web Soil Survey. Keep in mind that VCE notes construction (compaction, cut and fill, topsoil removal) may have changed the native soil around a newer house.

Step 3: Pick the fix that matches the cause

A small low spot: NVSWCD gives two options. Replant it with water-tolerant plants (preferably native), or fill it: clear leaves and grass, fill with topsoil (fill soil near the foundation), tamp it, grade so water runs away from the house, then seed or sod (NVSWCD).
Water running toward the house: The ground next to the foundation should slope away from the walls (NVSWCD). WVU Extension suggests about a 2 percent slope away from the house when grading a lawn (WVU Extension).
Widespread sogginess: Redirect the water with swales, French drains, catch basins or downspout extensions. Or capture it with rain barrels, cisterns, dry wells, soil amendment or rain gardens (NVSWCD).
Runoff from pavement or a slope: VCE's wet-site list: plant cleared slopes with ground covers, mulch to slow water down, divert runoff with perforated drainpipe on or under the soil, dig shallow trenches, or plant trees high on a berm (VCE 430-026).
Always wet, no matter the weather: Look for a leak first. NVSWCD notes the actual source may not be where you see the water. If it's a natural spring or a wetland, there may be rules about what you can change.

Thinking about a dry well?

Check the soil first. A dry well only works if water can soak in. Montgomery County, Maryland, for example, only allows dry wells to take roof runoff (not patios, driveways or sump pumps). It requires soil testing and sets them back at least 10 feet from slab-on-grade buildings and 15 feet from other foundations (Montgomery County DPS). Your county's rules may be different, so call before you dig. Maryland Extension also reminds homeowners to call 811 to locate utilities before digging (UMD Extension).

If you'd rather plant than dig

Most trees want well-drained soil and get root rot on wet sites. UMD names river birch, baldcypress and sycamore as exceptions (UMD Extension). For more choices, see our wet-spot plants by zone and the wet yard and rain garden guide (flood maps and rainfall by state). Near the coast? Read what to plant in wet clay in Hampton Roads.

Common questions

How long should water stand in a yard after rain?

The Northern Virginia Soil and Water Conservation District says a yard that dries out within a day or two after a rainstorm is normal. Puddles that last several days point to a grading or infiltration problem.

How do I test my yard drainage?

University of Maryland Extension: dig a hole 12 inches deep and 12 inches wide, fill it with water, refill it the next day, and the water should drain within eight hours. Less than 1 inch per hour is too slow.

Can a dry well fix a soggy yard?

Only if the soil lets water soak in. Montgomery County, MD, for example, allows dry wells for roof runoff only, requires soil testing, and sets them back 10 to 15 feet from foundations. Check your county’s rules first.
