Flooding in the Guadalupe River watershed drove a surge into Canyon Lake. See photos of high water and debris.
The extraordinary rainfall last week in Guadalupe River watershed was equivalent to more than 50% of the area's average annual rainfall and generated a massive flood wave that eventually poured into Canyon Lake, spiking the reservoir's water levels. As of 10 a.m. Tuesday, Canyon Lake stood at a surface elevation of 909 feet above sea level. That's an increase of 21 feet over the past week. The reservoir is now considered 100% full, a level that hasn't been reached since November 2021. Canyon Lake levels had hit an all-time low just over a year ago, in May 2025. At that point, lake levels had dropped to just 876.96 feet above sea level, leaving the lake only 45.1% full.
