Terry Anderson reports that the aquatic plant survey was done the week of May 13, later than normal because of slow growth from a colder winter. He has not yet heard back from the DNR but expects chemical application to be done the first week of June. We will post maps and notices as soon as the DNR tells us where we can administer application. Contact Terry at terry@whitewaterlake.org if you need special attention at your shoreline.
Proposed Aquatic Herbicide Application for Eurasian watermilfoil and Curlyleaf pondweed control on Whitewater Lake.
The Whitewater and Rice Lakes Management District (the District) with support from the Wisconsin Department of Natural Resources (WDNR) and Clean Lakes, Inc. (CLI) proposes to assess and chemically treat up to 175 acres on Whitewater Lake to control the excessive growth of the exotic invasive aquatic plants, Eurasian watermilfoil (EWM) and Curlyleaf pondweed (CLP). The District proposes to conduct an application of Weedar 64 (2, 4-D), Aquathol K (endothall), and ProcellaCOR (florpyrauxifen-benzyl) to be performed by CLI. We anticipate the treatment to occur sometime in spring, 2019 and will proceed only after the District obtains a permit for the treatment from the Wisconsin Department of Natural Resources.
Notification of the exact dates of treatment and water use restrictions associated with the use of Weedar 64, Aquathol K and ProcellaCOR will be provided by the posting of shoreline in and adjacent to treatment areas, and public access points.
The water use restrictions associated with use of the above pesticide as noted:
21 Day Irrigation Restriction
For additional information on the proposed treatment including a completed copy of the permit application, DNR Chemical Fact Sheets on 2,4-D, endothall and florpyrauxifen-benzyl as well as proposed treatment map please visit : www.district.whitewater.org

PUBLIC NOTICE
The Whitewater-Rice Lakes Management District (the District) proposes to chemically treat up to
175 acres of Whitewater Lake to control excessive growth of the exotic invasive aquatic
plants, Curlyleaf pondweed (CLP) and Eurasian watermilfoil (EWM). Clean Lakes, Inc. will
conduct an application of the aquatic herbicides Aquathol K, Weedar 64 and ProcellaCOR to
infestations. It is anticipated that the treatment will occur sometime in Spring, 2019 and will
proceed only after the District obtains a permit for the treatment from the Wisconsin Department of
Natural Resources.
The water use restrictions for Aquathol K, Weedar 64 and ProcellaCOR are as follows:
There are no swimming or fishing restrictions. Do not use water from treated areas for irrigation
purposes for 21 days after treatment, or until an approved assay indicates the 2,4-D concentration
is 100ppb (0.1ppm) or less. The District will hold a public informational
meeting on the proposed treatments if five or more individuals, organizations, special units of
government, or local units of government request one in writing. The person or entity requesting
the meeting shall state a specific agenda of topics including problems and alternatives to be
discussed. The request for a public informational meeting must be sent in writing to the Whitewater
