Antecedent reservoir levels determined flood control success on the Guadalupe River

Two floods hit Canyon Dam. The smaller one, in 2002, caused catastrophic damage downstream. The larger one, in July 2025, the biggest flood in the Guadalupe's recorded history, was attenuated by 98.9%, releasing only 389 ft³/s. The difference was not storm size but antecedent storage: the reservoir was drawn down by drought. Protection is contingent, not structural.
