How Baylor County floods

Flash flooding from heavy rainfall dominates the local flood profile, accounting for 17 of the 21 recorded flood events over the last 30 years, alongside 4 general flood events.

Recent impacts are documented in NOAA storm records, including multiple rounds of heavy rainfall that caused significant urban and river flooding across Baylor and Knox Counties in June 2024. An upper trough combined with tropical moisture to produce additional flooding events in September 2016.

National Flood Insurance Program records indicate minimal claims history, consisting of two claims in Zone UNKNOWN with an average payout of $1,429 and an average recorded water depth of 0 inches, and one claim in Zone A with a $19,744 average payout and an average recorded water depth of 2 inches. Properties located within Zone A and areas prone to rapid stormwater accumulation should pay the closest attention to local flood risks.

From the storm reports

Flash Flood · Jun 11, 2024. Multiple rounds of heavy rainfall from the 10th into the morning of the 11th led to urban and river flooding across portions of western-north Texas. The most significant flooding occurred across Knox and Baylor Counties.

Flash Flood · Sep 24, 2016. As a large upper trough moved through and combined with some tropical moisture, abundant rainfall produced flooding across the area on the 24th.

Flash Flood · Jul 8, 2010. Moist, tropical air remained in place over northern Texas, with scattered showers and thunderstorms remaining a daily late morning into the afternoon occurrence. A weak boundary stalled close to I-44 by early afternoon. Weak flow aloft did not allow for much movement of any thunderstorm, and with precipitable water values well over two inches, intense rainfall occurred over many areas. Flash flooding occurred over…

Flood insurance in Baylor County

If a building in Baylor 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.
