With 17% of homes built before 1960 and about 3 hard-freeze nights a year, frozen and split pipes are a leading winter risk in the county.
April brings the most downpours to Miller County, part of 17.8 heavy-rain days a year. Check the sump first.
Sewage backups in Miller County spike on heavy-rain days, about 17.8 a year, when sewer mains fill up and water finds the lowest drain.
Miller County's wettest day in the 2015–2024 record brought 4.9 inches, and about 31 freeze-thaw days a year mean ice dams in some winters.
4% of occupied homes in Miller County heat mainly with wood or propane, below the Arkansas county median of 10.9%.

Local risk profile
With 19,844 homes and around 42,360 residents, Miller County is 624 square miles of southwest Arkansas. The county seat is Texarkana, and Genoa, Fouke and Garland round out the largest towns. The county's median home was built in 1983.
52/100 Water Damage Risk Index: Elevated Miller County ranks 36 of 75 Arkansas counties. See the statewide ranking and method.The three factors where Miller County ranks highest compared with other Arkansas counties.
Miller County is milder than most of Arkansas, but not mild enough to skip winterizing. It averaged 32 freezing nights a year over 2015–2024, 3 of them at 20°F or colder, cold enough for pipes in outside walls and crawl spaces to freeze. Among 75 Arkansas counties that's 68th.
On February 16, 2021 the low fell to about 0°F, and in the stretch ending February 2021 the county went 4 days in a row below freezing. Leaks from split pipes typically appear the day the thaw arrives.
Most freezing nights fall from midwinter, peaking in January. Disconnect garden hoses and shut off outdoor spigots before the first hard frost, and keep the heat at 55°F or higher if you'll be away.
On average the first fall freeze arrives around Nov 12 and the last spring freeze around Feb 27.
Heavy rain is a bigger factor here than in most of Arkansas. About 17.8 days a year bring an inch or more (23rd of 75), most often in April, out of 58.1 inches of total precipitation. On April 30, 2016, 4.9 inches fell in a single day. Multi-day storms matter most for basements; the wettest three days on record here totaled 7.77 inches (through March 11, 2016).
Freeze-thaw days, below freezing overnight and above it by afternoon, come about 31 times a year here. They're the main driver of ice dams and of water working its way through foundation cracks in late winter.
Housing
46% of homes in Miller County predate 1980, close to the Arkansas county median of 46%, which ranks 37th of Arkansas's 75 counties.
The mix runs from 17% built before 1960 to 24% built since 2000, so older neighborhoods bring aging pipe while newer subdivisions bring failed appliance lines and water heaters.
The 1980s and 1990s account for 30% of the county's homes. If yours is from those decades, look under the sinks and at the water heater for gray plastic pipe stamped PB, which is polybutylene and leak-prone.
14% of homes are manufactured or mobile homes, close to the Arkansas county median of 15%. Their water lines run under the floor behind the skirting, so a torn skirt or failed heat tape freezes them faster than lines in a site-built house.
Renters occupy 36% of homes. If you rent, the building is usually the landlord's to repair, but your belongings are only covered by renters insurance.
Beyond water
Miller County averages 126 warm, muggy nights a year (lows of 65°F or more) and gets the most rain in April. Keep indoor humidity under 60%, as the EPA advises, and dry any leak within 24 to 48 hours; in a humid month a wet basement left alone won't dry by itself.
Mold remediation: what to expectMain heating fuel in Miller County's occupied homes: 36% utility gas, 58% electric, 3% propane and 1% wood. Most homes here heat with gas or electricity, so cooking and electrical faults are the likelier fire sources. Even a contained kitchen fire can send soot through the ductwork to every room.
