How Robertson County floods

Flash flooding from severe storms dominates the flood history of Robertson County, TN, accounting for 36 out of 43 total flood events recorded over the last 30 years by the NOAA Storm Events Database.

Recent events illustrate this recurring hazard. During a major severe weather and flooding event on February 15–16, 2025, well above-average moisture brought very heavy rainfall to the area, resulting in significant flooding in Robertson County where numerous roadways were flooded and several homes were impacted. A subsequent potent storm system brought multiple rounds of thunderstorms on March 15, 2025, producing additional flash flooding and flooding across the region.

National Flood Insurance Program records show claims spanning multiple zones, indicating that risks extend beyond designated high-risk areas. Zone A accounts for 36 claims with an average payout of $35,369 and an average recorded water depth of 6 inches. Meanwhile, Zone X recorded 26 claims with an average payout of $31,342 and an average recorded water depth of 9 inches, and Zone X_UNSHADED recorded 5 claims with a higher average payout of $94,711 and an average recorded water depth of 14 inches. Homeowners, real estate agents, and journalists should pay the most attention to properties in both high-risk Special Flood Hazard Areas and unshaded moderate-to-low risk zones where substantial flood depths and payouts have been documented.

From the storm reports

Flood · Mar 16, 2025. A potent storm system brought multiple rounds of thunderstorms and severe weather to Middle Tennessee on March 15, 2025. The main risk for severe weather was associated with a line of thunderstorms that tracks east across Middle Tennessee during the afternoon and evening hours. This line produced one EF-1 tornado near Christiana. As this line moved towards the Cumberland Plateau, it strengthened and caused wind da…

Flash Flood · Jun 15, 2025. Scattered thunderstorms impacted Middle Tennessee during the afternoon and evening hours of June 16, 2025. With above normal atmospheric moisture values, these thunderstorms were capable of producing very heavy rain. This combined with very slow storm motions led to a flash flooding threat. The heaviest rain recorded was in southern Maury County where radar estimates and gauges in the area measured four to five in…

Flood · Feb 15, 2025. A major severe weather and flooding event unfolded across Middle Tennessee on February 15-16, 2025. As well above average moisture spread into the area, this helped set the stage for very heavy rainfall across Middle Tennessee. Showers and thunderstorms began early during the day on February 15th, and the primary threat with this first round was flooding. The most significant flooding was reported in Montgomery an…

The zones you’ll see on the map

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.

Flood insurance in Robertson County

If a building in Robertson County is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.

Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
