Forggensee, with its length of twelve kilometers and three kilometers width, is the largest lake in the Allgäu and the fifth largest in Bavaria. He is not a natural lake. The Forggensee was first developed as a reservoir in the fifties, serves as a reservoir for the Lech downstream hydroelectric power plants and is important for the flood control of the Lech during snowmelt. The special feature of the Forggensee: It only has the full damming height from June to mid-October. In winter you can see in the empty lake the remains of the Roman military road Via Claudia Augusta, which led through the middle.

After the dam renovation, there is now another parking space directly at the top of the weir system.

The bridge crosses a high barrage.
The color of the lake is a stunning bright turquoise! Absolutely worth seeing (if not just drained off

Currently still no direct cycling possible for cyclists. Is everything still cumbersome about the Behelfsholzkonstruktion.Besonders for e-bikers, this can be a challenge

In terms of area, the lake is the largest reservoir in Germany.

It's well worth seeing: on one side, the dammed lake, on the other, the land below. A must-see.

We were here in 10/2019. The construction site was gone or we overlooked it.

The dam is tight again and has got a wonderful bike path. The cost of dam renovation was around 30 million

Come to this place on a summer evening and fall. Don't ask why, just do it! 😉

If there has been heavy rain in the Lechtal and Königswinkel again for several days, then check the overflow from the road! When water runs through it, turn around and turn off at Tiefenbrugg / Kögel and drive / walk down to the power station building. There you can watch live why the exit is called “Tossbecken” 😉

The dam repair has long been completed. You can't see anything of the repair, but the dam is an imposing structure even without repairs.
