The leader of the total maximum daily load (TMDL) study of impaired waterways along the lakeshore is scheduled to brief the Kewaunee County alternative technologies work group on the plans at the group’s next meeting.

Keith Marquardt of the Wisconsin Department of Natural Resources plans to update the workgroup during the meeting, which begins at 1 p.m. June 21 in the 4-H Room of the Fairgrounds Exhibition Building, 625 Third St., Luxemburg.

“He will discussing the TMDL implementation process on the East Twin River and the Ahnapee River,” County Conservationist Davina Bonness told the Kewaunee County Land & Water Conservation Committee last week. “He will be giving us the how, when, where … it’ll be great information to know.”

TMDL is a regulatory term in the U.S. Clean Water Act, describing a plan for restoring impaired waters that defines the maximum amount of a pollutant that a body of water can receive while still meeting water quality standards.

Bonness said the study will identify “hot spots” of pollution along the rivers, which will help officials enforce those standards and move toward improved water quality.

The DNR recently released a report on a portion of the East Twin River roughly from County Road J to Ellisville; the 2017-19 state budget includes funding for a TMDL study for the entire rivers of Door, Kewaunee, Manitowoc and Sheboygan counties and the streams that lie in and between the Ahnapee River watershed and the Sauk Creek watershed.
