No, but we do have some rough guidelines to follow. First of all, anyone tubing should be a good swimmer. This isn’t a lazy river with lifeguards. All the creeks and rivers in our area that are good for tubing have some whitewater. Boulder creek is not recommended for kids under 13 unless the flow is below 75 cfs. The St. Vrain in Lyons is good for younger kids, but swimming ability is still a must. Clear creek in Golden is good for kids at flows below 300 cfs. Swimming ability is a must, once again. Also, we strongly recommend life jackets and PFD’s for kids. The creeks around us are real creeks, with real rocks. And rocks hurt. Don’t sacrifice safety (and our helmets look really cool anyway). Tubing is really fun, and we rarely hear of incidents. We really want all of our customers and anyone recreating in the rivers and creeks to be safe, and respect the river and have fun out there!
It means Cubic Feet per Second. It’s a way of measuring water flow in a river or creek. If a creek is running at 200cfs, you can imagine 200 basketballs full of water flowing past a given point in a second. To give an idea of river flow, Boulder Creek, which is pretty small, runs between 100 and 200 cfs during the summer. During spring runoff, it can get up to flows over 1,000 cfs. An average flow in the Grand Canyon is about 10,000 cfs (since the dam was built. Before that it got up to 100,000 or 200,000cfs on an annual basis) Average spring flow on a small-medium sized river such as the Eagle River near Avon, Colorado is about 2,000-5,000 cfs.
Not without a permit. See the City of Boulder’s website for information.
We definitely do not recommended this for safety reasons.
