The McDill Inland Lake and Rehabilitation District (the District) proposes to chemically treat up to 100 acres of McDill Pond to control excessive growth of exotic invasive aquatic plants. Clean Lakes, Inc. will conduct an application of the aquatic herbicide Reward (diquat) to infestations. It is anticipated that the treatment will occur May 30 or 31st.
The water use restrictions for diquat are as follows:
There are no swimming or fishing restrictions. Do not use water from treated areas for irrigation purposes for 5 days after treatment.
McDill Inland Lake Protection and Rehabilitation District at its annual meeting passed a Resident Fertilizer Restriction that goes into effect immediately for its 176 residents. The general fertilizer restriction replaces the lake district’s former phosphate free fertilizer restriction since all fertilizers now sold in Wisconsin are phosphate free. The restriction limits residents to twice a year fertilizing their yards, unless a soil test proves the need for additional fertilizing. There is no limit on the amount of application of weed killers or other pesticides for nuisance control. A water study conducted by the WI DNR over two years found high amounts of nitrogen entering McDill during the winter months from groundwater and spring runoff. Due to the sandier soils around McDill, it is an important first step to control the amount of nitrogen entering McDill starting with the yards that have the greatest impact on McDill Pond. The restriction is to be self regulating, and currently does not have any fines for violations of the restriction. McDill Pond is also participating in efforts to promote healthy shorelands and work with local municipalities to address the high nitrogen levels entering McDill pond from various sources to mitigate the excess weed and algae growth in McDill Pond. A copy of the restriction is below for reference.
updated-harvest-map-122916 This is the updated revision completed by the Lake District and submitted to the Wisconsin DNR for use in 2017. The harvesting map was updated to increase some areas on the southern half by the business 51 causeway, smooth out some corners for easier harvesting and connect one lane to another. The skimming map will stay the same for 2017. Skimming is different than plant harvesting as it allows algae mats to be skimmed with the smaller harvester ONLY when the DNR is notified and approves 24 hours prior to skimming each time. Please note the change in the cutting areas allowed vs previous years, as clear cutting is not allowed, and instead navigation channels will be cut. Only 70% of the acreage of a waterbody may be harvested.
