Rivers are invaluable for city settlement, as they supply fresh water and enable the Water Mill (and various wonders) to be built. With it, any city may get a good start at growing and producing as early as the Ancient Era! An Aqueduct built next to it will also supply a nearby city with Fresh Water for Housing purposes.
But rivers do more than that. They provide a bulwark against invasions for any commander that knows how to use them; they turn Deserts into paradise by enabling the Floodplains feature; elsewhere they allow improved farming with the Civil Engineering Civic; they improve commerce thanks to the additional transport opportunities they provide for merchants.
Finally, you may use a River as means of finding the nearest sea in your early exploration. Every river flows from its source to either another river, or to a large body of water - just follow the flow direction.
Gathering Storm brings a whole new level of strategy to rivers: they are now areas of one of the brand new disasters: the flood. Pay attention to the areas marked as Floodplains (they can appear now not only in deserts, but also in plains and grassland areas) - they are the ones which will flood during disasters! You can still develop them normally, but floods may damage, or even outright destroy your improvements and districts placed there! However, they will also enrich the soil, adding Food and/or Production to their base yields, and making them potentially even more useful than before! So, developing floodplains becomes a calculated risk which may bring lots of pain or rich rewards.
Gathering Storm introduced a new mechanic in which Rivers can have different names based on the first civilization that finds them. Below is a list of river names and, where applicable, the civilization/s they are assigned to.
