Sorry for this late reply.
As for generator 2+, the river algorithm is:
1. Pick a random spot which is not ocean.
2. If it is surrounded by 1 or 2 river tiles,
   it has 100% chance of becoming a river tile.
3. If it is surrounded by 1 to 3 ocean tiles,
   it has 1% chance of becoming a river tile.
4. Repeat until there are enough river tiles.
Simple?
Caution: many of the codes in mapgen do not do
         what they are originally meant to do.
