The 2015 Blanco flood is the local high-water lesson
Two major floods hit Hays County in 2015. Water swept away homes and took lives. It also broke gauges, crossings, and flood works. The county built better river tools after crews saw gaps in the old system.
For land near the Blanco, start with FEMA's map. Then ask the county about newer flood data, drainage, and old high-water marks. A lender may not ask about every way water can reach a home.
During a storm, stop the land research. Follow current county alerts. Never drive around a gate or into water over a road.
