| South-Central Texas |
| February 20 to 22, 1958 |
| Heavy rains Feb. 20-22 caused major flooding on
many small streams in central and South Texas. In the Brazos
River Basin, as much as 6 in. of rain caused flash flooding
on Brushy Creek and the Lampasas and San Gabriel Rivers. In
the Colorado River Basin, flooding generally was confined to
the narrow part of the basin downstream of Austin. Major flooding
also occurred in the Guadalupe River Basin downstream of New
Braunfels. Victoria was the only city in the Guadalupe River
watershed to experience any serious flooding. About 26 blocks
of the city were flooded requiring the evacuation of about 350
people. In the Nueces River watershed, flash flooding occurred
in the upper basin. Major flooding occurred in the Nueces River
and its tributaries below Cotulla in La Salle County. |

| Deaths and Damage: |
Flooding from the storm caused two deaths on the Guadalupe
River, and damage exceeded $1 million. |
