Supervisors hear options to fix Orton Slough drainage problems


Woodbury County officials continue to hear opinions on a slow-flowing drain situation that's causing concern near Salix.

The county's engineer says a drain that was build over 100 years ago, which leads to a 20-inch tile in the Orton Slough drainage district, isn't up to agricultural standards. Over the past nine months the county's engineer has worked with an engineering consulting firm to study the drainage on the Orton Slough.

Tuesday, they presented possible solutions to fix the flooded area with price tags of between $500,000 and $800,000. The cheapest option would replace the existing tile with an open ditch. But, county leaders fear that would hinder crop production. "If you're taking 20 acres out of production, it's four dollars an acre in 20 years, that's 300,000 dollars of crop production you're taking away," said Larry Clausen, Woodbury County Supervisor.

Board members are also concerned that an open ditch will cause more sediment to move into Brown's Lake. "We are trying to make sure that those issues are addressed by including a trap system and settle out sediment and water that's coming out the open ditch system," said Ivan Droessler, Civil Engineer.

The engineering consultants will prepare a final report and a set of preliminary plans to present to the board in 60 days.
