These are the generally accepted river ratings for normal water levels indicated. Weather and water conditions can drastically alter the nature and difficulty of any river. Water level is extremely critical and it should be determined prior to accepting these general river guidelines. Ratings are not a substitute for careful scouting and a realistic evaluation of one's own paddling skills. Ratings are indicative of the paddler skill level required to attempt the entire section not just the difficulty of individual rapids.
| Average Gradient | Maximum Gradient | Volume river vs Gradient |
| Width of River | Ease of Rescue | Inaccessibility |
| Difficulty of Rapids | Continuousness and/or rapid length | Obstacles, rocks, trees, undercuts |
| Water Temperature |

When Comparing Two River Sections
A lower rating does not mean that you can't run a harder section, only that you will be much more challenged
| +/- 1 point | Very Similar |
| +/- 2 points | Noticeable Difference |
| +/- 3 points | Meaningful Difference |
| +/- 5 points | Profound Difference |
