CNN’s Josh Cambell reports on questions over a lack of flood warning signals and lagging investment in river gauges in Kerr County after deadly floods killed over 100 people in Central Texas.

Kerr County

Officials in Kerr County, Texas, are under scrutiny after catastrophic floods claimed more than 100 lives. Questions have arisen regarding the effectiveness of the county's flood warning systems, including whether timely alerts were issued and received, and the absence of an audible siren system.

Local authorities acknowledge the complexity of evacuation decisions and cite budgetary and logistical obstacles to upgrading warning infrastructure, such as installing more river gauges and sirens. Experts and former officials argue that the region's early warning system is outdated and insufficient for a flood-prone area, calling for increased state investment to prevent future tragedies.

Officials face questions over preparedness for Texas floods

I think everyone in Kerrville, everyone in Kerr County wishes to God we'd had some way to warn them. As authorities continue search and rescue efforts in the Texas Hill Country, questions are sharpening over whether more could have been done to avert a tragedy that has claimed more than 100 lives. Local officials have yet to provide a clear accounting of whether an ominous warning from the National Weather Service early Friday morning was pushed out via a cell phone alert to people in the flood path. It's not that easy when you just push a button. Okay, there's a lot more to that. Well, evacuation is a delicate balance. Local officials say the decision to order public evacuations is a complex one because if you evacuate too late, you then risk putting buses or cars or vehicles or campers on roads into low water areas trying to get them out. The weather service did their job. The watches and warnings went out clearly. The heartbreak with respect to this development is that those warnings were not received. In addition to text alerts, questions have been raised about the lack of an audible warning system to alert residents of danger. It's clear that one thing that could help in the future, it would seem no matter what other redundancies we have our sirens, it could blast very loudly. A CNN investigation found multiple efforts in Kerr County to build a more substantial flood warning system. Former Kerr County Commissioner Tom Moser told CNN the area is perhaps the most flood prone in the state of Texas and described the county's early warning system as pretty antiquated and marginal. At best, Moser said he studied how a nearby county installed sirens and suggested Kerr County do the same. But the idea was met with resistance, he said, due to budget concerns and noise. According to a transcript of one local government meeting in 2016, another county commissioner said the thought of our beautiful Kerr County having these damn sirens going off in the middle of the night, I'm gonna have to start drinking again to put up with y'all. Sirens are important, but a siren, a weather forecast is always going to run the risk of being too late. Another area under scrutiny, the number of gauges along the Guadalupe River that can alert officials in real time to rising waters. The upper Guadalupe River Authority does have at least five gauges on the river in Kerr County, but experts say that number should be doubled or even triple. How can you have a timely warning when you have no system? How can you have a timely warning when you have no data? One major hurdle cost electronic gauge systems can cost tens of millions of dollars, often far beyond what anyone county can afford. River management veterans say it's past time for the state of Texas to do its part to cover the price. There's only one lesson that comes out of this to me that's worth anything, and that is that the state of Texas steps up because if they don't, the world's watching us and what a failure that will be.
