Drone footage shows parts of Frankfort, Ky., underwater after the Kentucky River reached its second-highest crest on record. Here's what to do after a flood.

On Sunday, the Kentucky River crested at 48.27 ft, just shy of the record of 48.5 ft set in 1978. It will remain in major flood stage through early Wednesday, with waters slowly receding. Here's what to do after a flood impacts your area.

First, only return to your home or business after the local authorities give you the go-ahead. Floodwaters can hide many hazards, such as electrical lines, hazardous substances and wildlife. Next, do not drive or wade through floodwaters.

Floodwater is often contaminated with sewage, bacteria and other harmful materials. Avoid it as much as you can. Do not use floodwater for washing, bathing or any other purposes.

After the waters recede, stay cautious. Roads and foundations may have been weakened by the flooding.
