| RAPID_CLASS | The relative difficulty of traversing a rapid, based on the International Scale of River Difficulty. | |||
| CLASS_I | Class I: Easy. Fast moving water with riffles and small waves. Few obstructions, all obvious and easily missed with little training. Risk to swimmers is slight; self-rescue is easy. |   | 11 | |
| CLASS_II | Class II: Novice. Straightforward rapids with wide, clear channels which are evident without scouting. Occasional maneuvering may be required, but rocks and medium sized waves are easily missed by trained paddlers. Swimmers are seldom injured and group assistance, while helpful, is seldom needed. Rapids that are at the upper end of this difficulty range are designated "Class II+". |   | 12 | |
| CLASS_III | Class III: Intermediate. Rapids with moderate, irregular waves which may be difficult to avoid and which can swamp an open canoe. Complex maneuvers in fast current and good boat control in tight passages or around ledges are often required; large waves or strainers may be present but are easily avoided. Strong eddies and powerful current effects can be found, particularly on large-volume rivers. Scouting is advisable for inexperienced parties. Injuries while swimming are rare; self-rescue is usually easy but group assistance may be required to avoid long swims. Rapids that are at the lower or upper end of this difficulty range are designated "Class III-" or "Class III+" respectively. |   | 13 | |
| CLASS_IV | Class IV: Advanced. Intense, powerful but predictable rapids requiring precise boat handling in turbulent water. Depending on the character of the river, it may include large, unavoidable waves and holes or constricted passages demanding fast maneuvers under pressure. A fast, reliable eddy turn may be needed to initiate maneuvers, scout rapids, or rest. Rapids may require "must'' moves above dangerous hazards. Scouting may be necessary the first time down. Risk of injury to swimmers is moderate to high, and water conditions may make self-rescue difficult. Group assistance for rescue is often essential but requires practiced skills. A strong Eskimo roll is highly recommended. Rapids that are at the lower or upper end of this difficulty range are designated "Class IV-" or "Class IV+" respectively. |   | 14 | |
| CLASS_V | Class V: Expert. Extremely long, obstructed, or very violent rapids which expose a paddler to added risk. Drops may contain large, unavoidable waves and holes or steep, congested chutes with complex, demanding routes. Rapids may continue for long distances between pools, demanding a high level of fitness. What eddies exist may be small, turbulent, or difficult to reach. At the high end of the scale, several of these factors may be combined. Scouting is recommended but may be difficult. |   | 15 | |
| CLASS_VI | Class VI: Extreme and Exploratory. These runs have almost never been attempted and often exemplify the extremes of difficulty, unpredictability and danger. The consequences of errors are very severe and rescue may be impossible. For teams of experts only, at favourable water levels, after close personal inspection and taking all precautions. After a Class VI rapids has been run many times, its rating may be changed to an appropriate Class 5.x rating. |   | 16 | |

| ALL_WEATHER | An all-weather route has the following characteristics: (1) With reasonable maintenance, passable throughout the year to a volume of traffic never appreciably less than its maximum capacity. (2) Normally formed of roads which have waterproof surfaces and are only slightly affected by rain, frost, thaw or heat. (3) Never closed because of weather effects other than snow or flood blockage. |   | 11 | |
| FAIR_WEATHER | A fair-weather route has the following characteristics: (1) Passable only in fair weather. (2) So seriously affected by adverse conditions that the route may remain closed for long periods. (3) Improvement of such a route can only be achieved by construction or realignment. |   | 12 | |
| LIMITED_ALL_WEATHER | A limited all-weather route has the following characteristics: (1) With reasonable maintenance, passable throughout the year but at times the volume or traffic is considerably less than maximum capacity. (2) Normally formed of roads which do not have waterproof surface and are considerably affected by rain, frost thaw or heat. (3) Closed for short periods of up to one day at a time by adverse weather condition during which heavy use of the road would probably lead to collapse. |   | 12 | |
