2021 CLP Treatment is scheduled for Sunday evening 5/16/21
Treatment area map below - LSIA will treat approximately 95 acres for CLP in 2021 compared to 122 acres in 2020. The areas to target and acreage recommendations are the product of the Early Spring Curlyleaf Pondweed survey conducted by Eric Fieldseth of AIS Consulting Services on behalf of the Lake Sarah Improvement Association. The report can be viewed via this link in .pdf format
Areas 1 2 3 4 10 and 12 are tentatively scheduled for Monday 5/17/21, with aquathol, subject to weather. (See information and use restrictions on Aquathol below the map.)
The remaining zones are tentatively scheduled the following week, with diquat. The permit has been approved. (See information and use restrictions on Diquats below the map.)
LSIA is targeting early June for the milfoil survey with treatment to follow. Based on what Eric saw in the CLP survey, and the hybrid milfoil, it is probably a fair bet that we will be looking to treat more milfoil than in recent years.
2021 Curlyleaf Pondweed Treatment areas
Aquathol K information
Aquathol K is a non-selective liquid aquatic herbicide containing 40.3% dipotassium salt of endothall as the active ingredient.
PLANTS CONTROLLED: Bur Reed, Coontail, Hydrilla, Milfoil, Naiad, Pondweed (American, Curly-leaf, Flat-stem, Floating-leaf, Horned, Illiniois, Largeleaf, Narrowleaf, Sago, Threadleaf, and Variable-leaf), Parrotfeather, and Water Stargrass. Under optimum conditions, 7-21 days are required before the desired level of aquatic weed management is achieved.
USE RESTRICTIONS: Waters treated with Aquathol K may be used for swimming, fishing, and irrigating turf, ornamental plants and crops immediately after treatment with the following exceptions: Do not use the treated water to irrigate annual nursery or greenhouse crops including hydroponics and newly seeded or transplanted annual crops, newly seeded or transplanted ornamentals, and newly sodded or seeded turf for 7 days after the treatment. Do not use treated water for animal consumption within the following periods: 0.5 ppm dipotassium salt - 7 days after treatment, 4.25 ppm dipotassium salt - 14 days after treatment, 5.0 ppm dipotassium salt - 25 days after treatment. For drinking water, concentration of endothall acid in the water should be less than 0.1 ppm at the time of consumption. Treatment should not be made within 600 feet from functioning potable water intakes.
Diquat (Reward) Information
Reward is a non-selective contact liquid aquatic herbicide containing 37.3% diquat dibromide as the active ingredient. It provides broad range control of resistant algae and submerged, floating and emergent plant species.
PLANTS CONTROLLED: Floating/marginal plants including Water Lettuce, Water Hyacinth, Duckweed, Salvinia, Pennywort and Cattails. Submersed plants including Bladderwort, Hydrilla, Milfoil, Pondweed (except Richardson's Pondweed), Coontail, Elodea, Brazilian Elodea, Naiad and Algae (when used in conjunction with algaecide). Under optimum conditions, 5 - 21 days are required before the desired level of aquatic weed management is achieved.
USE RESTRICTIONS: Waters treated with Reward may be used for fishing and swimming immediately after treatment although swimming may cause drift of the active ingredients or suspension of sediments which will reduce effectiveness. Do not use treated water for drinking for 1-3 days following treatment (depending on application rate). Do not use treated water for animal consumption for 1 day following treatment. For irrigation of turf and landscape, wait 1-3 days after treatment (depending on application rate). Irrigation of food and production crops should not occur until 5 days after treatment.
The most recent water level reading of 2021 was 978.86' on May 11 (east bay gauge)
This can be compared to the initial reading this spring of 979.32 on 4/9/21, the final reading last fall on November 8, 2020 of 978.38' and the Ordinary High Water Level for Sarah of 979.90'. More information on past years water levels can be found on the Water Levels page on this website.
LSIA’s aquatic invasive species consultant Eric Fieldseth from AIS Consulting Services LLC, has provided a summary for the upcoming LSIA Spring newsletter. click here to view Summary of 2020 CLP and EWM Management on Lake Sarah by Eric Fieldseth, AIS Consulting. This includes some very informative historical background information, along with a summary of our treatment in 2020 including post treatment survey. Eric is the independent consultant that LSIA hires to help conduct the surveys and guide decisions for treatment of the invasive weeds.
We have made great improvements in controlling the invasive weeds since we began to treat them in 2012. Anyone who has lived on this lake before the treatment started knows the significant improvement in the water quality of the lake over the years.
The LSIA board has already met and are busy working with their partners (Three Rivers Park District, Pioneer-Sarah Creek Watershed Management Commission, DNR and AIS Consulting) to make plans for the 2021 lake treatment.
Lake Treatment Donation
The estimated cost to treat the invasive weeds in 2021 is around $36,000, which is consistent with the amount spent the last two years. We continue to get some financial support from Three Rivers Park District and Pioneer-Sarah Creek Watershed Management Commission. We have applied for some possible grant money and recent indications from the DNR are positive for some reimbursement post treatment. Treatments typically are applied in May/June each year pending survey results and weather conditions. In order to continue the treatment and improve the quality of our lake we need your continued financial support.
We are again asking all lakeshore residents and dock owners to donate $150.00
