  • Exactly. But it looks like such sources exist maximum for selected countries level (for example Russia or USA). To be honest i thought that exploring different countries rivers is more popular between canoeists.

American Whitewater offers the National River Database.

The river list selection page gives an overview of real-time information that we can track on a state-by-state basis. We track information for the United States, Canada, Mexico, the Dominican Republic and Costa Rica.

I don't see an export option, but if you contact them and have good motives, then maybe they can help. Otherwise, the HTML is easy enough to "parse".

As for the "difficulty", the state pages have a table with the Class.


And individual rivers have more info
