[Hydropower dams](https://www.materialinsights.org/energy/e_hydro_dams/) (energy) and [Natural reservoirs](https://www.materialinsights.org/energy/e_natural_stores/) (energy): 2 relationships.

## How they are linked

### 1. Energy flow

*Physical flow · Direct · Hydropower dams → Natural reservoirs*

The reservoir behind a dam stores water for dry seasons.

### 2. Energy flow

*Physical flow · 94% of flow · Natural reservoirs → Hydropower dams*

Snowmelt and lakes refill hydro reservoirs.

- **94%** of Natural reservoirs's energy goes this way
