i would go with the 3rd, since it still allows for the floodplain to be seen but also clears up the "busyness" of just having it traced like a lake/coastline. this could also be useful for regions like russia/north canada which look like marshes with how it's set up.Ok, the Paraná basin is almost ready, there is only one small problem, the Paraná river delta (not the La Plata river) is somewhat screwed, despite having a path that can be separated from the delta area, it is similar with the center of the Amazon but more concentrated and basically it is floodplain, do you think it would be interesting to represent this with a different color (similar to a dry lake) to leave with nothing? (This also happens with other rivers to)
