Flood Warning System Rejected Before Devastating Texas Flood

Officials in Kerr County, Texas, where a catastrophic flood recently claimed the lives of 27 campers and staff, had previously considered installing a flood warning system along the Guadalupe River, known as “Flash Flood Alley,” but the project was dismissed due to its high cost.

Back in 2017, the county—home to about 50,000 residents—explored options including sirens, river gauges, and advanced communication tools to alert the public. However, budget constraints led to the decision not to proceed. County Commissioner Tom Moser explained, “We can monitor water levels all we want, but if the information isn’t relayed to the public quickly, it’s ineffective.”

Further, Kerr County’s annual budget of roughly $67 million limited its ability to finance such a system, and the county missed out on a $1 million grant application aimed at funding the project. It remains unclear how much installing a flood warning system would have cost specifically.

Instead, local officials relied on informal communication methods to pass flood warnings upriver from the camps. Kerr County Judge Rob Kelly noted that residents were hesitant about funding a warning system, citing the high costs involved. “Taxpayers won’t pay for it,” he stated.

In neighboring Hays County, a flood warning system developed in 2015 cost around $2 million, with part funded by a state grant. Former Kerr County commissioner Moser, after visiting Wimberley’s advanced flood alert setup, advocated for similar measures in Kerr County. Unfortunately, the proposal was abandoned due to budget fears.

While Moser admits such a system might not have entirely prevented the recent tragedy, he believes it could have mitigated its impact, potentially saving lives in a region dubbed “Flash Flood County” because of its environmental conditions.
