Heavy rain fell on the North Georgia mountains overnight from November 4 into November 5. Parts of northern Gilmer and southern Fannin counties had 5 to 6 inches in a few hours (WSB-TV, November 5), and a weather station near Blue Ridge recorded 11.19 inches in under six hours (National Weather Service report). The National Weather Service put McCaysville under a Flash Flood Emergency, and the Toccoa River reached 18.05 feet, above its previous record of 17.8 feet set in February 1990 (Atlanta News First, November 5, citing NOAA data).

Water got into homes and businesses. McCaysville Police Chief Michael Earley said water downtown was 6 to 7 feet deep in places and had risen over the roofs of some homes, and crews made more than 30 water rescues overnight (Atlanta News First, November 5). By the morning of November 6, officials said swiftwater teams had rescued more than 80 people, and dozens of homes and businesses had been destroyed (Atlanta News First, November 6). Police told residents on West and East Tennessee Avenue to leave immediately; several downtown businesses took water, several Fannin County families were displaced, and multiple homes flooded in Gilmer County (Yahoo News, November 5). Emergency managers reported water in several homes on Bushy Head Road off Boardtown Road near Cherry Log, and water in a home on Old CC Camp Road in Murray County. Across the state line, law enforcement reported water going into homes in the Grassy Creek community near Copperhill, Tennessee, where the river (the Ocoee on that side) left its banks downtown (National Weather Service reports, November 5).

Governor Brian Kemp declared a state of emergency for Fannin, Gilmer, Murray and Union counties on November 5 (WSB Radio, November 5). Shelters opened at McCaysville City Hall, Copperhill City Hall and the Fannin County Recreation Center, and schools in Fannin and Gilmer counties closed on November 5 (Atlanta News First). On November 6 the McCaysville water system was out of service, a boil water advisory was in effect, and the city was handing out water at the building behind City Hall (Atlanta News First, November 6). If water got into your home, cabin, garage or ground floor in McCaysville, Blue Ridge, Cherry Log, Ellijay, the Chatsworth area or Copperhill, this page is for you. You may not need to spend anything on mold. Here is how to tell.

The first days after: what matters now

EPA guidance is that wet building materials dried within 24 to 48 hours usually do not grow mold. River water that sat in a home for hours, or rose to the ceiling, is past that point for most of what it touched, so the question is how wet things got and how fast you can dry the rest. Wait for officials to say an area is safe before you go back in, and keep the power off in any room where water reached outlets until an electrician has checked it.

1. Get standing water and mud out, then get air moving. River floodwater leaves silt behind. Shovel and hose it out while it is still wet, then run fans and a dehumidifier once power is safe.
2. Pull what soaked. Wet carpet pad usually goes. Drywall that took water usually comes out a foot or so above the water line, along with wet insulation behind it.
3. Check crawl spaces and lower levels. Many homes and cabins on these slopes have a crawl space, a basement or a walkout lower level. Water and mud can sit there long after the main floor looks dry.
4. Treat floodwater as dirty water. River and creek water carries sewage, fuel and runoff. Wear gloves and boots during cleanup. Porous items it soaked (mattresses, upholstered furniture, cardboard) are usually thrown out.
5. Photograph everything first. Water lines on walls, damaged items, and the outside of the house. Insurers and any later assistance programs rely on them.
6. Check what sits low. Water heaters, furnaces and heat pumps, well pumps, washer and dryer, and outlets near the floor. If water reached them, have them checked before you rely on them. If you are on a private well that flooded, have the water tested before you drink it.

If it is a cabin you don't live in

A lot of homes around Blue Ridge and Ellijay are second homes or rental cabins. If you are not there, ask a neighbor or your property manager to photograph the water line and open the place up once it is safe. A cabin closed up wet for a week or two is where mold gets ahead of you. Tell your insurer as soon as you know water got in, even if you cannot get there yet.

Do you need a mold test?

Often, no. If you can see mold, EPA says sampling is usually unnecessary: the job is to remove the wet material and fix the moisture. A test earns its cost when you smell mustiness but cannot find the source, when you are buying or selling, or when a landlord or insurer disputes what happened. Our cost guide lays out honest price ranges.

For a small area (EPA uses roughly 10 square feet as the line), most homeowners can handle cleanup themselves with gloves, an N95 and bagging the material. Larger areas, or moisture inside walls and crawl spaces, are where a professional makes sense. An inexpensive moisture meter will tell you more than a mold test.

Insurance: what usually applies

• Most homeowners and renters policies exclude flood, and water from a river or creek that rises into the home is treated as flood. Flood coverage comes from a separate flood policy (NFIP or private).
• If you have flood insurance, report the damage, and keep the photos and receipts for drying equipment and supplies.
• Water that came through a damaged roof or window can be handled differently from water that flowed in at ground level. Read the exact policy language or ask your agent.
• New NFIP policies usually have a 30-day waiting period, so a policy bought now would not cover this event.
• As of November 6, there is no federal disaster declaration for this flooding. Governor Kemp's state of emergency covers Fannin, Gilmer, Murray and Union counties. Watch Fannin County and Gilmer County emergency management and your city's website for local assistance.

Is it urgent, or can you slow down? An honest triage

Renters: a Georgia note

Georgia law (O.C.G.A. § 44-7-13) requires landlords to keep the premises in repair. Report water damage to your landlord in writing and keep a copy. See our renters guide.

A note on storm-chasing contractors

After flooding, door-knockers follow. Be wary of anyone who wants a large deposit up front, asks you to sign over insurance payments, pressures you to decide today, or will not give a written estimate. Get more than one quote, and check a contractor's license with the Georgia Secretary of State's licensing lookup (sos.ga.gov). On the Tennessee side, use the Tennessee Board for Licensing Contractors.

Frequently asked

The water only covered my garage or basement floor. Do I need to do anything?
Probably not much for bare concrete, which dries on its own. Check the bottom of any drywall, stored boxes, and anything in contact with the floor, and clear out the silt.

Will bleach fix it?
Not on drywall or wood. Porous material with mold growth should be removed. Bleach is for hard, non-porous surfaces, and never mixed with ammonia.

McCaysville flooded in August too. Does that change anything?
It can. Materials that got wet in August and were not fully dried, or were patched over, are more likely to have hidden growth now. Mention the earlier flood to anyone who inspects or quotes the work.

The water is gone. How do I know the walls dried?
A moisture meter reading at the bottom of the drywall, compared with a wall that stayed dry, is the simplest check. Readings that stay high after a few days of drying usually mean the material should come out.
