Designing a Timberborn watershed for storage and expansion

The map places water sources in deep basins so that each spring forms a small reserve instead of draining at once. Most of the water can escape through one low outlet concealed by foliage, while narrow channels from the higher sources create smaller losses. This restriction turns an apparently resource-rich map into a storage problem: the player can eventually block the outlets, raise the water level and support a much larger settlement. The terrain retains that future capacity because the design favors a city that can keep evolving after its early problems are solved. Timberborn abstracts real hydraulics, but the map still asks the player to read a watershed, reserve capacity and plan infrastructure for later growth.
