Aquatic Plant & Weed Control
2023 Weed Treatment Information Invasive Species Information Annual Treatment and Chemical Use Notice
Primary aquatic plant and weed treatment will be applied when the water is warm enough and there are undesired weeds present that need treatment, generally in late May or early June. Any additional treatments will be applied as needed throughout the summer.
To assist with treatment notice posting you are encouraged to place a stake near your shoreline to which the notice can be stapled. Otherwise the notice will be affixed near your shoreline to your dock, a post, or a tree.

Treatment Schedule Limitations Our contractor does his best to treat on the scheduled days, but wind, rain, and other factors may cause delays to the planned treatment day. RLI Members have also requested no treatments on Friday, Saturday, or Sunday, no treatment the week before the fishing contest, and no treatment the week of July 4th. This often makes our spring treatment, which normally occurs in early to mid June, a bit challenging. Why is wind a concern? Weed control is accomplished by contact herbicides. When it is windy the water on and below the surface is moving. The applied herbicides therefore do not remain in contact with the targeted weeds long enough to slow their growth. Calm water provides the best results when treating aquatic weeds.

2018 Treatment information: (for reference)
Current treatment plan, subject to weed growth and weather:
5/7/18: We are trying to get a head start on Starry Stonewort control in the cove, and algae control in both the cove and channel. Treatment for these areas occurred on 5/7. This is a copper treatment only, for which there are no water use restrictions.
5/29/18: We have planned our first significant aquatic weed treatment of the year for Thursday, May 31st, weather dependent. Subtropical depression Alberto is projected to impact our weather Wednesday thru Friday, which may impact our treatment date. This first treatment focuses on non-native weeds, specifically the invasive weed Eurasian Milfoil (the long, fluffy stalks with red tops currently found along the drop-off, and actually touching the surface in many locations), as well as Curly Leaf Pondweed, another invasive. The Milfoil was so bad last fall and this spring we are going to try a more aggressive treatment. We will also be doing our second treatment for Starry Stonewort in the cove.
6/6/18: Aquatic weed treatment occurred on Wednesday, June 6th. Please be aware the more aggressive treatment approach to better control Eurasian Milfoil uses a systemic chemical that has water use restrictions. These restrictions can be found on the yellow notices along the shoreline of treated areas. These restrictions include:
This is the excerpt from your Annual Weed Treatment Notice (reference your Spring Newsletter – may also be found online) for the applied chemical. 2,4-D (Dichlorophenoxyacetic Acid, Butoxyethl Ester): Do not use the treated water for swimming for 1 day. Do not use the treated water for irrigation, agricultural sprays, watering dairy animals, or domestic water supplies. "Irrigation" includes water gardens--however, it does NOT include watering lawns. Lawn spray companies often use 2,4-D to kill weeds in lawns --watering lawns when only 2,4-D has been applied will not hurt your lawn (but see restrictions on the other products). "Domestic use" means using lake water inside your house. Fish and wildlife are not affected. 6/13/18: Aquatic weed treatment occurred on Wednesday, June 13th. This was a touch up of some new Eurasian Milfoil areas. Please be aware the more aggressive treatment approach to better control Eurasian Milfoil uses a systemic chemical that has water use restrictions. Please refer to the yellow notices in these areas as well as the restriction information in the 6/6 treatment information above.
6/25/18: Aquatic weed treatment occurred on Monday, June 25th. This was a touch up of some Eurasian Milfoil areas, and treatment of the cove for Starry Stonewort. Please refer to the yellow notices in these areas as well as the restriction information in the 6/6 treatment information above.
7/10/18: Aquatic weed treatment occurred on Tuesday, July 10th. This was a touch up of some Eurasian Milfoil areas, and treatment of the cove and other areas for Starry Stonewort. Please refer to the yellow notices in these areas as well as the restriction information in the 6/6 treatment information above.
7/19/18: Aquatic weed treatment occurred on Thursday, July 19th. This was a treatment of Milfoil in the cove. Water use restrictions apply. Please refer to the yellow notices in these areas as well as the restriction information in the 6/6 treatment information above.
8/2/18: Aquatic weed treatment occurred on Thursday, August 2nd. This was a treatment for Starry Stonewort in the cove and other areas, and a Milfoil spot treatment. Water use restrictions may apply. Please refer to the yellow notices in these areas as well as the restriction information in the 6/6 treatment information above.
8/23/18: Aquatic weed treatment occurred on Thursday, August 23rd. This was a treatment for Starry Stonewort in the cove and other areas, and a Milfoil and Pondweed spot treatment. A contact herbicide was used, so short duration water use restrictions may apply. Please refer to the yellow notices posted in the treatment areas.
2018 Weed Treatment Notices:
(5/7/18) This treatment will be for the cove Starry Stonewort, and the cove and channel algae only.

(8/30/13) The lake will be toured the first week of September to determine if additional treatment is needed.
(8/13/13) Weed treatment occurred this morning (Tuesday) despite windy conditions. Underwater application techniques were used to control chemical distribution.
(8/12/13) Treatment was further delayed on Monday, August 12, due to weather.
(8/7/13) Due to storms in our area, aquatic weed treatment has been rescheduled for Thursday, August 8th. Additional delays resulted from a defective gate lock.
(8/4/13) Our lake was toured on 8/2, and a treatment plan was developed. Our next scheduled aquatic weed treatment is Wednesday, August 7th, weather permitting. A map showing the treatment locations can be found above. Not all areas of the lake are being treated. Treated areas will have yellow signs posted with information about any water use restrictions which apply to your immediate area.
(7/16/13) The lake was treated as scheduled. Treatment Map - 7/16/13 Posted Treatment Notice - 7/16/13
(7/12/13) Our lake was toured on 7/7, and again with our contractor on 7/10. Our next scheduled aquatic weed treatment is Tuesday, July 16th, weather permitting. A map showing the treatment locations can be found on our website within the next 24 hours. Not all areas of the lake are being treated. Treated areas will have yellow signs posted with information about any water use restrictions which apply to your immediate area. The annual notice with specific chemical information and use restrictions can be found in your spring newsletter, and on our website aquatic plant & weed control page.
This treatment is focusing on Milfoil and Pondweed, typical for this time of year. We will also be treating the cove and channel areas for Starry Stonewort. We continue to look at other options for the Starry Stonewort situation but have limited options at this time.
Treatment Map - 6/4/13 Posted Treatment Notice - 6/4/13
(6/3/13) The lake was toured on 5/26/13 to evaluate several areas that may need treatment. Treatment is scheduled for Tuesday, June 4th. The areas to be treated can be seen using the treatment map link above.

Annual Treatment Notice (from Spring Newsletter) 2012 MDEQ Permit
The lake was toured on 8/1/12 to evaluate several areas that have not responded well to prior treatments, along with the cove entrance and boat ramp areas (Starry Stonewort is growing). Treatment was then applied on Wednesday, August 8th. We are waiting on a treatment map.
The lake was treated the morning of Monday, July 9th. Milfoil and broad leaf Pondweed is breaking the surface in many areas around the lake. You may reference the new treatment map and notice using the above links.
The lake was toured on 5/25/12. After a number of delays related to wind and rain our first treatment occurred the morning of June 12. Our first treatment targets Curly Leaf Pondweed, Broad Leaf Pondweed, Northern Milfoil, Starry Stonewort, and algae. Reward and Cutrine are being used on the Pondweed and Milfoil, and Aquathol will also be used in the cove so restrictions will be 24 hours for swimming and 3 days for watering. Copper is being used in the cove and channel areas to treat algae. As discussed during the Spring General Meeting, Clipper is also being tried in the areas near the outlet, as recently permitted by the MDEQ. This product dissipates in less than 24 hours, so again a 24 hour restriction in that area applies. The actual treatment notice posting can be accessed above.
A note about treatment delays due to wind: We know this is frustrating for many of our Members. However, with our weed bands being so narrow, spraying the chemicals onto the surface of the water when it is moving 3 - 5 mph results in little uptake of the chemical by the plants below due to very rapid dispersion. We are just throwing money down the drain if we treat in conditions like this and would have to retreat at additional expense.
2011 Treatment information: (for reference) Treatment Map - June 2011 Posted Treatment Notice - 6/21/11 Treatment Map - August 2011
Touch-up Treatment - Thursday, August 4th. Our contractor treated areas identified as "undesirable growth". See map above.
Reassessment - Friday, July 29. Our contractor will be touring the lake to establish a plan for an early August touch-up treatment.
Treatment occurred Tuesday, June 21st. This was a general treatment for Northern Milfoil, Pondweed, and algae in the channel. The lake was toured on Saturday, June 11th. See the treatment map link above for approximate treatment areas. If you have questions or concerns please contact Ivan Quinn or email us. Please watch for notices, which include water use restriction details, along your shoreline.
2010 Treatment information: (for reference)
Week of July 11. Likely July 12 or 13. Click here for the treatment map which shows the areas to be treated in crosshatch. Please watch for notices, which include water use restriction details, along your shoreline just prior to treatment. We will post the treatment day as soon as it is determined.
Thursday, June 10, 2010 for Pond Weed and Elodea Specific Treatment Notice - 6/10/10 Because of the cool spring weed growth thus far is limited to cool water weeds, such as Pond Weed. Aquatic Nuisance has determined the best treatment method is to spot treat the Pond Weed and some Elodea in early June and follow up with treatments for Northern Milfoil and other weeds as they grow to the point of requiring treatment. This treatment plan will not only keep unneeded chemicals out of the lake but will also save us the cost of chemicals that would have limited effect. Click here for the treatment map which shows the areas to be treated in crosshatch. Please watch for notices, which include water use restriction details, along your shoreline just prior to treatment. We will post the treatment day as soon as it is determined. Click here for a copy of the yellow notice posted along shorelines in the treatment areas.
