Old dam for the silver mines - a photo on Flickriver

Old dam for the silver mines

            Køsje was dammed to float timber to the silver mines. Mainly for fuel , but also for pit props and other building in the mines. Dual function: It increases the length of the lake - then, when the gates are opened, it gives enough water flow to float the timber down the creek.

Constructed by filling log boxes with rock.

The dam can't have seen maintenance for 100 years or more, but it is still tight enough to keep the water level up. (The gates are stuck by now.) More important - it fails gracefully, it will never burst. When the logs disintegrate, that will leave a heap of rocks. Probably a gradual decrease in the water level, but no flash flood. Compare that with failing to maintain a nuclear power plant.
