COLA Petitions WDNR to List Correct Cause of Impairment for Lac Courte Oreilles in 2018 Impaired Waters List

Every two years, Section 303(d) of the Clean Water Act requires states to publish a list of all waters that are not meeting water quality standards. In the proposed 2018 list update, the Wisconsin Department of Natural Resources (WDNR) proposes to add 240 new water segments.  The WDNR issued a notice on November 15, 2017, soliciting public comments on its proposed 2018 list of Impaired Waters. The WDNR is proposing to list all of Lac Courte Oreilles as impaired—which is a good—but, it is proposing to list “low dissolved oxygen” (DO) as an indicator, or symptom, of that impairment without citing Total Phosphorus as the cause of the impairment. During the Public Comment Period, through Dec. 29, 2017, the Courte Oreilles Lakes Association (COLA) and others are requesting that the WDNR also correctly list the cause of the low DO impairment of LCO (click here for the full story).

Please help by sending a letter or email requesting that the WDNR amend the listing by including the correct reason for impairment — Total Phosphorus. A sample message is available here.

The following is from the WDNR: “Public comments may be submitted by December 29, 2017, and can be emailed to DNR at, or sent by U.S. mail to Ashley Beranek, DNR, Water Evaluation Section (WY/3), Box 7921, Madison, WI 53707. Comments postmarked or received by December 29, 2017, will be considered before submitting the final draft list to the U.S. Environmental Protection Agency for approval.”
