What happened on the Guadalupe — in public records, step by step
Two catastrophic floods hit the same basin twelve months apart. This investigation examines both using gauge records, driller’s logs, monitoring wells, LiDAR, and the State’s own filings — every figure sourced, every computation reproducible. Each one below stands on its own. Start wherever your question is.
