How about using bridges to act like dams instead of actually transforming a river hex?My thoughts:
Bridges are changed to dams.
Dams block shipping of other players.
Use 1 dig to build a dam.(or act1)
When other players' shipping come across a dam, they can use 1 dig to remove it.
Since dams can be removed, they cannot be part of a town.
And Stronghold upgrade 1 dig track.
It gives more interactions between players, with beavers having the ability to annoy their opponents with efficient digs.
It also gives beavers options to play on the field(not too river focused)
and provide a cap of 3 dams at the same time.
