In September, WORD completed the flood warning system project from Canyon Lake into New Braunfels. Funding partners on the system are WORD, New Braunfels, Comal County, and Guadalupe County. This system has two components, river gauges and sirens.
The sirens are located at bridge crossings at FM 306, 4th, 3rd, 2nd, and 1st crossings on River Road. Each of the gauge sites at the siren locations has two pressure transducers which measure the river height. When that height gets above a set level, it will notify Emergency management, then automatically set off the siren. We also have the ability to set off the sirens remotely if we know water is headed downstream.
While the sirens are the more visible and talked about part of the system, the real power of the setup is in the gauges. The data from each gauge including river height and rainfall will be available online for everyone to monitor in very close to real time. This will allow businesses and residents to view the river height at each bridge crossing upstream from them and make safety decisions based on that data.
WORD is hopeful that adding this tool to the safety toolbox will make it easier for everyone to predict and react to rising water when it occurs.
Monthly siren testing will occur on the first Tuesday of each month between 10-11am. This will include sirens at the four bridge crossings on River Road and the FM 306 Horseshoe at Maricopa. Sirens will sound for a maximum duration of 4 minutes.
In the event that it is raining, testing will be rescheduled.
