Re: Proposed Management for Exotic Invasive Species control on McDill Pond.
Dear McDill Pond Property Owner or Occupant:
The McDill Inland Lake and Rehabilitation District (the District) proposes to assess and manage up to 55 acres of McDill Pond to control the excessive growth of the exotic invasive aquatic plants Eurasian watermilfoil (EWM), its hybrid (HWM), and Curlyleaf Pondweed (CLP).
The District proposes to conduct applications of Flumigard SC (flumioxazin), Aquathol K (endothall), and/or Tribune (diquat) to be performed in the spring of 2025 by TIGRIS Aquatic Services, LLC (TIGRIS), proceeding only after the District obtains a permit from the Wisconsin Department of Natural Resources. Notification of the exact dates of application(s) and water use restrictions associated with the use of these herbicides will be provided by the posting of shoreline in and adjacent to treatment areas, and public access points.
Flumigard SC and Tribune have up to 5-day irrigation restriction. All other activities may go uninterrupted. There are no water use restrictions associated with use of Aquathol K.
TIGRIS will post signs day-of herbicide application at each treatment zone indicating products used in that area.
Additional details regarding the proposed management, including a copy of the permit application and the WDNR aquatic herbicide fact sheets on these herbicides, can be found at: www.mcdillpond.com.
For questions about the proposed management or a hard copy of the permit application, please contact: Krista Olson McDill Inland Lake and Rehabilitation District [email protected]
