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.
