Stauseen, or reservoirs, are artificial lakes created by damming rivers or streams. They store water for various purposes, including drinking water supply, irrigation, and hydroelectric power generation. These bodies of water can also help control flooding and provide recreational opportunities like fishing and boating. The construction of Stauseen involves building a dam to hold back water, creating a large storage area. The water level in these reservoirs can fluctuate based on rainfall, usage, and seasonal changes. Proper management is essential to balance ecological health, water supply, and recreational needs.
