Changes may be ahead for the Mississippi River Gorge

A public meeting was held on July 13 at St. Peder’s Evangelical Lutheran Church to discuss possible changes within the Mississippi River Gorge. Well over a hundred people attended the meeting, which 12th Ward Council member Andrew Johnson called to order. Representatives of government and non-profit agencies presented background information for the first hour, after which the meeting was opened up for questions.

“The 8½-mile-long Mississippi River Gorge begins at Upper St. Anthony Falls, drops 110’ over its course, and ends at the confluence with the Minnesota River,” explained National Park Superintendent Jon Anfinson. The Gorge is a unique part of the 72-mile-long Mississippi National River and Recreation Area, which falls under the jurisdiction of the National Park Service. Anfinson continued, saying, “Below the Gorge, the Mississippi is a floodplain river that extends to the Gulf of Mexico.

The U.S. Army Corps of Engineers will decide by mid- August whether or not to embark on a two-year process called a “disposition study” for this stretch of the river. That study would determine if it is in tax payers’ best interests to continue paying for the Upper and Lower St. Anthony locks, and the Ford Lock and Dam within the Gorge. According to Nan Bischoff, U.S. Army Corps of Engineers project manager, “the annual cost to taxpayers to operate, maintain, and repair these facilities is $1.5 million.”

The dam at Upper St. Anthony Falls is not part of the possible disposition study, as it belongs to Xcel Energy.

Brian Graber is a dam removal specialist with American Rivers, a regional organization out of Rock Island, IL. “Removing dams is an effective strategy,” Graber said. “Since 1999, 1,380 dams have been removed across the US. Of those, 49 have been removed in Minnesota; the national average for dam removals is 27 per state. There is no faster and more efficient way to bring a river back to health than to remove a dam.”

Mike Davis, a river ecologist with the DNR, said, “Everyone is worried about invasive species traveling upstream. The best way to stop invasive species is to clean up the river. We know that Bighead and Silver Carp have been seen in Minnesota waters but, to our knowledge, they have yet to reproduce here. Many of us believe that if water quality and native fish species were restored, the invasive species could be kept in check.”

We have an award winning boathouse facility just north of the Lake St. Bridge, a site we’ve occupied since 1965. We believe that our club deserves a seat at the discussion table, and to date, we have not been included.” (Photo by Margie O’Loughlin)

One of the closing questions from the audience was, “Given the reality of global warming, and the pressing need for clean energy, why remove the Ford Dam which supplies hydropower for some 30,000 nearby homes?”
