The Red River Drainage Raises Flood Risk in Parts of Fannin County

The Red River and Bois d'Arc Creek drain Fannin County, and FEMA flood maps show which areas face the highest flood risk.

Fannin County Home & Property

Fannin County borders Oklahoma along the Red River. The river and Bois d'Arc Creek are the county's main drainage systems. Low-lying areas near these waterways can flood during heavy rain. Annual rainfall in the county averages just over 43 inches.

Before you buy property, look it up on the FEMA Flood Map Service Center. Search by address to see if a parcel is in a high-risk flood zone. Homes in a Special Flood Hazard Area may be required to carry flood insurance if they have a federally backed mortgage. The Texas Flood Information Viewer is another free tool for checking local flood data.
