International Dredging Review

International Dredging Review

The Upper Mississippi River Channel Maintenance Management Plan was ready in April 1996 but it had been 20 years in the making.

Contained in a four-inch-thick binder the document contains information on the river from Guttenberg Iowa to Minneapolis Minnesota 245 miles of river with 10 locks and dams under the control of the St. Paul District Corps of Engineers. The plan also includes several navigable tributaries that feed into the Mississippi.

“We wanted the plan to be all inclusive so all the companies and agencies we work with can reference our programs” said Dan Krumholz Waterways chief for the St. Paul District. “We talked about programs procedures and policies and we wanted to document past activities we had good records for” he said.

Steve Tapp Channel Maintenance Coordinator also played a major role in assembling the plan said Krumholz.

“We’re using it every day as our own guide and other agencies are using it also. If someone calls with a question and has the book he can reference an exact page allowing us to answer the question” he said.

There were good records on dredging projects to 1975 including reference to dredged material placement sites. This information was incorporated into the report.

“An important part of the plan is that it is a place to identify our plans for the future about dredged material” he said. “The site maps and information sheets serve as a guide for other agencies and internally so anyone can look up how any site will be developed and used in the future.”

They also addressed channel control structures and the St. Paul District’s plan for them.

“Other things we are commonly asked is about beneficial uses guidelines for removing material from the site including past testing of the material” he said. “We tried to make the report as comprehensive as possible and accessible to everyone we interact with” he said.

The document is clearly tabbed with descriptions of laws and regulations interagency coordination district mitigation policy sediment analysis procedures placement evaluation procedures a summary of all the dredge cuts and historical information on all the cuts from 1975 to the present.

Detailed maps of each dredge cut and primary and auxiliary placement sites take up the bulk of the document. Information sheets contain background information site characteristics such as “type I wetland” site dimensions beneficial use if any terrain that might present limitations on equipment restrictions future plans and status of all necessary permits.

Dan Krumholz has been with the St. Paul District for 27 years. He grew up in Fountain City Wisconsin the location of the Upper Mississippi River project office.

“I have never lived far from the river” he said. “A lot of our people (in the St. Paul District) who grew up on the river become involved with it in their work. They are working with the resource they grew up with; they place great value on it” he said.

Krumholz began his career working on the District’s crane barge and then on the Dredge Thompson for six years attending college off and on and receiving a degree in biology from Winona State College in the early 1970’s.

Today he is chief of the Waterways Section of the Mississippi River Project.

The CMMP has been submitted for the Corps of Engineers Design and Environmental Awards program. Each year districts nominate projects for this Corps-wide award which is announced in April. The St. Paul District won the award once before for Weaver Bottoms an environmental enhancement project using dredged material.
