For more than a century, a gated dam in Pine River, Minn. held back the water that flowed out of Norway Lake into the Pine River and eventually to the Whitefish Chain of Lakes.

The Norway Brook dam was a centerpiece of the small north-central Minnesota city of about 900 residents, a summertime gathering spot for its annual summer festival and for kids itching to cool off.

This is how shallow dams can be removed while preserving lakes that have become important to the local human population.
