For realtime updates about lake-and-river conditions visit wordcc.com or Canyon Lake (army.mil). This page is updated daily, not hourly.

During periods of heavy rain, flow rates can change rapidly and become dangerous. Central Texas is known as “flash-flood alley.” To see rates in realtime, visit this page maintained by the U.S. Geological Survey and look for Guadalupe Rv at Sattler, TX. Closures of the Comal River inside New Braunfels city limits will be posted on the New Braunfels Police Facebook page.

For a better understanding of how release rates work and how they affect flow rates on the lower Guadalupe visit this page maintained by the Water-Oriented Recreation District of Comal County (WORD).
