In Kerr County, where the most deaths occurred, officials said they were receiving threats, even as they continued to deflect questions about flood warnings.
Flash floods surged through in the middle of the night, but many local officials appeared unaware of the unfolding catastrophe, initially leaving people near the river on their own.
Kerr County had discussed buying such things as water gauges and sirens after previous flood disasters. But as with many rural Texas counties, cost was an issue.
