As part of our ongoing effort to preserve and improve the water quality and recreational enjoyment of Lake Minnewashta for all, the LMPA will be treating Aquatic Invasive Plants again this year. We wish to keep all of you well informed and this is Notice that we will be treating various areas of Lake Minnewashta for AIS in 2023.
We have performed the first of two planned weed surveys on the lake to determine the concentration of Curly Leaf Pondweed (CLP) around the lake. You can find the survey below. That survey was performed by Carver County staff. The second survey for Eurasian Water Milfoil (EWM) will occur later in June.
Our plans to reduce the impact of the growing invasive weeds include two treatment periods. The first treatment is for Curly-leaf pondweed(CLP) which is an invasive plant that grows in the spring and early summer. The objective of the curly leaf pondweed treatment program is to treat the heaviest growth of CLP to improve the water quality and recreational use of the lake. The proposed treatment areas may be within 150 feet of your shoreline.The DNR requires us to notify property owners of the treatment with this announcement. The treatment methods will follow Department of Natural Resources’ guidelines and permit.
Curly Leaf Pondweed will be targeted, as in previous years, with the chemical Dibrox (Active Ingredient 37.3% Diquat), an EPA and DNR approved chemical for this use and no restrictions for swimming or fishing following application. This treatment will be completed the week of May 28th as Curly Leaf Pondweed is actively growing now and needs to be performed at the correct water temperature.
If you do not want the treatment to occur adjacent to your property (within 150 feet from shore), please notify us immediately at info@lakeminnewashta.org.
Eurasian Water Milfoil will be targeted for treatment later this spring with the product 2,4-D This is an EPA and DNR approved product has also been very effective in the past and has also resulted in a reduction of the areas needing treatment. Treatment areas will be determined by June’s weed survey.
Float signs will be placed in the affected areas when these treatments are made. There are very few water use restrictions with these chemicals, but property owners should take note of the information on the float signs if treatment is done in their area. For more information, please contact us.
The cost of these treatments is funded by the generous donations of LMPA members and is an important step in maintaining the superior water quality that we all enjoy. If you are a lakeshore property owner or a fan of the lake and don’t already belong, please consider joining LMPA and help by providing a donation to support this important program. More information can be found on our website.
Thank you for your consideration and support!
