Conversion of a dam to a rapids
Fargo, ND/Moorhead, MN
Dams cause environmental and societal damage. They can create dangerous
hydraulic rollers that trap and drown people; they prevent fish and other
aquatic animals from migrating upstream to high-gradient habitats; they
prevent sediment from moving downstream; and they act as barriers to people
traveling up or down the river.
Removing
these dams eliminates all of these problems, but when that is not an option,
converting the dam to a rapids is the next best thing. This fills the
scour hole below the dam, eliminating the hydraulic roller and making
the dam safer, and enables fish to migrate upstream. Midtown Dam, which
was built in 1960, was not removed because the city wanted to maintain
a water intake pipe in the pool above the dam. Therefore, work began in
February 1998 to convert Midtown Dam to a rapids. After delays caused
by high water, the project was completed in February 1999. Since that
time, this site has become a popular kayak run. This project is part of
a larger effort to "Reconnect the Red", which will make all
of the dams along the Red River of the North-from Winnipeg, Canada to
Fergus
Falls, MN-passable to fish.
