Overview

Watershed is an educational sandbox that lets you draw a catchment area anywhere on Earth, pick a storm, and watch real elevation data come alive. Developed and published by Mozon, this simulation title launched on Steam on October 22, 2026.

It blends exploration, science, and nature into a hands-on learning experience that runs live on your graphics card.

The core idea is simple: you define a region, choose a weather event, and observe how water behaves across actual terrain. The game uses real elevation data, so every valley, ridge, and slope responds to rainfall in a physically plausible way.

Rivers carve their paths, lakes form in low spots, and eventually the water reaches the sea.

Highlights

  • Real Terrain, Real Water: Draw any area on Earth and watch real elevation data shape the flow of water, from tiny streams to major river systems.
  • Six Storm Presets: Choose from a desert cloudburst to a monsoon week, or fine-tune every parameter yourself to create custom weather scenarios.
  • Time Travel with Oceans: Drain the oceans back to the Ice Age or roll the atlas back to the Bronze Age, then send a caravan across the exposed land.

Who It's For

Watershed is perfect for educators, students, and anyone curious about hydrology, geology, or geography. It's also a relaxing sandbox for nature lovers who enjoy watching landscapes evolve under their control.

The tutorial and intuitive controls make it accessible even if you have no prior knowledge of water systems.
