Moving at the Speed of Water
The Guadalupe River watershed starts around Hunt, Texas and flows down through Canyon Lake, New Braunfels, Gonzales, Victoria and finally dumps into the Gulf of Mexico.
But if it's flooding in Spring Branch, and I am in Seguin, how fast do flood waters move? When will the water reach me?
These are great questions...and this chart shows various approximate flood travel times from point to point along the Guadalupe and Blanco Rivers. Flood water in Hunt can reach Canyon Lake in approximately 42 hours and water leaving Canyon Lake can be in New Braunfels in approximately 6 hours.
