Clarksville's Cumberland River Flood History
Clarksville has experienced major Cumberland River flooding events throughout its history, including significant floods in 1927, 1975, and most recently the catastrophic flooding of May 2010, when record rainfall sent the river to historic levels. In more recent years, significant flooding events have continued to affect the lowest-lying portions of the city. The construction of Cheatham Dam has moderated some flood risk, but the river remains a serious threat during major precipitation events.
Which Areas of Clarksville Are at Highest Flood Risk
The lowest-lying areas of Clarksville — particularly neighborhoods near the Cumberland River and its tributaries Red River, Muddy Fork Creek, and McAdoo Creek — face the highest risk. FEMA flood maps identify Flood Zone A and AE areas throughout lower Clarksville where flood insurance is required. However, flooding regularly extends beyond mapped flood zones during major events, affecting homes that have never flooded before.

Emergency Flood Preparedness for Clarksville Homeowners
Every Clarksville homeowner at any flood risk level should know the location of their main water shutoff valve, have sandbags or temporary flood barriers accessible for entry points, maintain a 72-hour emergency supply kit, keep important documents in waterproof storage, and have the phone number of a reliable water damage restoration company — (931) 271-2350 — saved in their phone before they need it.
What to Do Immediately After Flooding in Your Clarksville Home
Do not enter a flooded structure if electrical systems may be affected — call your utility company first. Turn off electricity at the breaker box if you can do so safely from a dry location. Do not use household equipment to extract water — residential equipment cannot handle flood volumes or find hidden moisture. Call (931) 271-2350 immediately for professional extraction and begin the insurance claim process with your carrier.
