Plans to develop a flood monitoring system in the Texas county hit hardest by deadly floods were scheduled to begin only a few weeks later.

A Kerrville-area river authority executed a contract for a flood warning system that would have been used to help with emergency response, local officials said.

Also: San Antonio mourned the victims in a Travis Park vigil; UTSA said one of its teachers died in the Guadalupe River flood; Kerrville officials said a privately owned drone collided with a helicopter conducting search and rescue operations.

Rain rushing to the Guadalupe took it from a depth of less than 8 feet to 37.5 feet, a deluge with as much volume as an aircraft carrier over five minutes.

The deadly Texas floods have brought the state's approach to land approvals, especially in flood-prone areas, under more scrutiny.

The flooding brought the Guadalupe to its second-highest point in history, according to the National Weather Service, which urged people in the affected area to move to higher ground.

FOX 4’s Steven Dial rode along the Guadalupe River with the sheriff of Andrews County, located in West Texas, to get his first-hand account of the recovery effort.
