U.S. Army Corps of Engineers is releasing water from Canyon Reservoir into the Lower Guadalupe River at a rate of 69 cfs.
The Corps is replacing Canyon Dam’s floodgate. Construction on the outlet is scheduled from Dec. 5 through April 15, 2023. Flow rates will vary drastically during this period. Flows will be turned off for up to 10 hours and then turned back on for 14 hours to allow for catch-up releases. To learn more about specific dates click here. If you plan to be on the water, see realtime updates hyperlinked below. 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).
