The Möhlin weir is a central control element of the Breisach cultural weir flood retention area and thus assumes an important function in its operation.
The Möhlin weir was put into operation in the 1960s as a subsidiary of the Breisach culture weir. Since then, it has enabled the Möhlin to be impounded, which, together with the impoundment of the Rhine at the Kulturwehr, supports and stabilizes the groundwater levels. In 2018, the regional council of Freiburg (RP) built a fish ladder at the Möhlin weir.

Frequently Asked Questions
What kind of fish pass is the Möhlin Weir and Fish Pass, and how does it work?
The Möhlin Weir features a vertical slot fish pass. This design consists of a series of 22 individual pools, arranged like a staircase, with narrow vertical openings (slots) in the walls. Water flows gradually through these slots, allowing fish to swim through without needing to jump. The pools are sized to allow fish to rest during their migration. To help fish find the pass, an additional bottom outlet creates a strong 'lure current' of 1,500 liters per second, guiding them towards the fishway's entrance.
Is the Möhlin Weir and Fish Pass suitable for families with young children?
Yes, the Möhlin Weir and Fish Pass is considered family-friendly. The terrain around the fish pass is generally gentle, making it suitable for leisurely walks. The educational information boards provide an engaging way for children and adults to learn about river ecosystems and fish migration. It's a great spot for an outing where you can combine education with enjoying the riverside scenery.
Are dogs allowed at the Möhlin Weir and Fish Pass, and are there any specific rules?
