Removal of two dams in central Iowa proposed

FORT DODGE (AP) — A proposed plan to remove two dams across the Des Moines River in central Iowa could cost more than $4 million and be completed next winter.

The proposal presented Monday to the Fort Dodge City Council calls for the removal of the Hydroelectric Dam and the Little Dam during the winter of 2018-2019.

Wade Greiman, project manager with engineering firm Snyder & Associates, said the dam removals would amount to an estimated $4.3 million. He said the Hydroelectric Dam removal would cost about $3.6 million and the Little Dam removal will cost about $750,000.

The dams would be replaced with structures to direct water and reduce stream bed erosion.

A riverfront master plan adopted by the City Council last year recommended the removal of the two dams.

“I think this is going to be a great improvement in the condition of the river,” said councilman Terry Moehnke.

Greiman said the dams would be removed in phases and that there are still multiple steps to be completed before demolition can begin.

Once the Hydroelectric Dam is removed, local leaders will have options of the type of structures to be built.

Nicole Church, an environmental specialist with Snyder & Associates, said a “J-hook” structure would direct water flow while creating fishing areas. Church said the other option, a rock crest weir, was used in Charles City to create a whitewater attraction on the Cedar River.

The funding for the removals will be included in a $9 million general obligation bond proposal, which the council will consider on March 12.
