Watershed layers with names for each one for Europe or Sweden?

Question

I am working on freshwater species and I would like, make a list of each watersheds used for each species.

So I am looking for a watershed maps which contain name of the watershed.

I found some good layers, but, they don't get names for each basins, only for the bigger ones.

I would like to know if someone can give me advices, links or good sources?

I need mainly the cover for Sweden at least, or Europe.

I searched this site, but I found most of the elements to create watersheds.
