Stauwehr Krün

Stauwehr Krün is a weir and small hydroelectric station on the Isar River in Bavaria that diverts water toward Walchensee lake for power production. The installation works by channeling the river's flow through turbines to generate electricity.

The weir was constructed in 1924 and immediately began holding back water. In 1990, regulations were introduced to ensure that downstream stretches received minimum water flow to protect river ecology.

This engineering structure represents Germany's early commitment to renewable energy, incorporating water management systems that balance power generation with environmental preservation.

The installation sits within a protected water management area with restricted public access. Those wishing to observe the weir and water systems can find viewing areas along the Isar riverbank nearby.

A fish ladder with 65 chambers allows fish to bypass the weir and swim upstream past the structure. This feature demonstrates how power generation and fish populations can coexist.
