Guadalupe River Flow Info

Many factors must be taken into consideration to fully understand what the conditions are like on the Guadalupe.
River Flow

Although we believe fishing is enjoyable anytime, a little planning and research will lead to a more successful trip. GRTU recommends only fishing when water temperatures are 68 degrees Fahrenheit or lower. And don’t forget to keep your fish wet, especially on days when air temps exceed 80 degrees Fahrenheit.
