Sometimes you get a bit of ocean thats trapped from the actual ocean and you can put ships on it when a city is on an ocean lake.
However you cannot do the same with freshwater lakes and it might be a good idea to allow this to happen. You could say move ships between lakes with cities between two lakes acting as a kind of lock. You could thus think of lakes strategically aiding moving, defending and attacking. Also maybe create a unique resource for freshwater lakes as they seem devoid of any. Maybe a lady of the lake resource with a sword rising out of it, fish and etc
