Event: Texas Flooding - Early July 2025 (Assessment Period)

Last Updated: July 21, 2025

Report File Name: 2025_July_Texas_Floods_report.pdf

Description: Heavy rainfall in early July triggered by Tropical Storm Barry resulted in catastrophic flooding across Central Texas, the Hill Country, and Concho Valley. Communities along the Guadalupe River, which reached a major flood stage, were devastated. Flash flooding resulted in significant loss of life, damage to property, and flooded croplands. The United States Department of Agriculture's National Agricultural Statistics Service (NASS) produced an assessment on the extent of potential damage to agricultural land and activities from this event. A disaster assessment was conducted using available Sentinel-1 Synthetic Aperture Radar (SAR) and cloud-free Sentinel-2 and Landsat 8/9 imagery coverage to identify likely inundated areas by the flooding event in early July 2025. Inundated areas were then compared to the 2024 Cropland Data Layer (CDL) to estimate crops potentially affected by the floods.
