New this Week
News this Week, June 1, 2026:
The installed sirens will be tested at 1:00 pm on Wednesday, June 3, 2026. This is only a test. It provides an important way to test system operations and remind the public what sirens sound like when activated. Thank you for your support as we work to strengthen emergency preparedness.
The Guadalupe River Flood Warning System public dashboard, called RiverHub, is now active! RiverHub, developed and operated by the Upper Guadalupe River Authority, brings together rainfall, river water level and streamflow, and forecast data from trusted federal, state, regional, and local partners to provide a unified view of river conditions across Kerr County and the surrounding Guadalupe River basin.

Welcome to Guadalupe River Flood Warning System (GRFWS)
Project goals: Flooding remains one of the most significant natural hazards affecting Kerr County, often developing rapidly and with limited warning. To increase available information, enhance public safety, and improve emergency response, the Upper Guadalupe River Authority (UGRA), Kerr County, and local cities have teamed up to implement the Guadalupe River Flood Warning System (GRFWS). The GRFWS is being designed and built to provide clear, timely flood information and alerts for populations in flash flood risk areas. The project will establish a strong foundation based on a network of river and rain gauges that monitor and report flood conditions every five minutes across a new telecommunications network dedicated to critical infrastructure. UGRA, in partnership with Kerr County, will build a network of strategically placed outdoor sirens to deliver audible warnings during flood events. The sirens will complement other Kerr County strategies for public notification.
The goal of this system is to improve our community’s flood awareness, response, and resiliency long term. Along the way, we will also comply with state requirements.
While sirens are a powerful tool to enhance public safety, they are not a substitute for personal preparedness. Every household should have an emergency plan, stay informed through official channels, and be ready to act when severe weather threatens.
Project Timeline
The GRFWS will be delivered in two main phases to ensure thoughtful planning, efficient deployment, and long-term reliability.
The first phase of the project focuses on providing sirens to support flash flood alerts for youth camps and surrounding areas on the North Fork and South Fork Guadalupe River in west Kerr County. Efforts have included hiring an engineering firm specialized in flood warning systems, procuring siren equipment from a reputable siren vendor, working with youth camp operators to determine where and how to install sirens, and coordinating with local and state agencies for funding and permits. Our next steps are to install the sirens (in mid-May), update County emergency action plans to include when, why, and how sirens will be activated, conduct public outreach and education to help the community understand what it means when a siren is activated, and deploy a watershed dashboard, RiverHub, that provides the public real-time information on river and rainfall conditions.
The second phase will include expansion of siren coverage to other critical flash flood risk areas in Kerr County, installation of additional river and rain gauges, development of software to help predict flooding, and broader public outreach and education.
