‘Flash-Flood Alley’

During periods of heavy rain, flow rates of both the Guadalupe and Comal rivers can change rapidly and become dangerous. Central Texas is known as “flash-flood alley.” Take rain events in Canyon Lake and New Braunfels seriously.

Closures of the Comal River inside New Braunfels city limits will be posted on the New Braunfels Police Facebook page.
