The city of East Grand Forks built an "Invisible Flood Control Wall" to protect the downtown area. The base of the floodwall will protect against flooding up to the 100-year flood level. If a higher flood is expected, the "Invisible Flood Control Wall" is assembled on the base, which will provide protection to a 60-foot river level.

The "Invisible Flood Control Wall" was developed in Germany, and was recently approved by the Army Corps of Engineers for use in the United States. East Grand Forks is the first U.S. city to install one.

"Invisible Flood Control Wall" is a registered trademark of Flood Control America

The old dike along the river has been removed, and the clay was used to build the new dike. The Blue Moose Restaurant was moved soon after this photo was taken, Nov. 1998.
