Call to order Mr. Raabe (Chair) called the meeting to order at 5:00 p.m. 2. Approval of the minutes of the meeting of July 28th, 2025 Mr. Raabe called for a motion to approve the minutes; motion was made by Mr. Haga and was seconded by Ms. Smith. Motion carried. 3. Review Pond management/treatment recommendations Ms. Anderson reviewed the treatment recommendations outlined in the draft aquatic plant management plan, focusing on priority concerns of algae, invasives, and nuisance aquatic plants. Ms. Anderson additionally noted that consultations were made with the DNR in formulating the recommendations, and what is provided are practical options for the Village. Ms. Smith asked what long-term evaluation consists of and if there are ways to track what is working. Ms. Anderson stated that the plan can always be reevaluated and updated to reflect changes and that any treatments on the Pond will have to be monitored and results recorded as part of a permit. Mr. Raabe inquired about who on staff would implement the plan or initiate the search for funding. Ms. Anderson stated that Community Development staff would take the lead. Mr. DeKleyn also noted that applying for grants would be one of the first steps in the process. Mr. Raabe asked if grants are regularly available and where they mainly come from. Ms. Anderson said that the Village has typically received grants from the WDNR such as surface water grants. Mr. Haga asked if it would be possible to utilize the university for work on the Pond. Ms. Anderson stated that if the university had interest, that staff could look into that in the future. Conversation was had about educating residents. Mr. Haga discussed encouraging residents to attend meetings to teach them about topics such as run-off and fertilizer effects on the Pond and how that is an important tool the Village could use. 4. Adoption of the Springville Pond Aquatic Plant Management Plan Ms. Anderson informed the committee that they are providing a recommendation for approval to the Village Board, who will then give final Village approval. The plan will then go to the DNR for approval. RECOMMENDATION TO VILLAGE BOARD: Mr. Haga motioned to approve the adoption of the Springville Pond Aquatic Plant Management Plan. Ms. Smith seconded. Motion carried. 5. Adjournment subject to call of the chair Mr. Raabe (Chair) called for a motion for adjournment, Mr. Haga motioned to adjourn, and Ms. Smith seconded at 5:20 p.m. Motion carried. Submitted by Karmen Anderson Village of Plover COMMUNITY DEVELOPMENT DEPARTMENT 2400 POST ROAD - PO Box 37 - PLOVER, WISCONSIN 54467 Phone: 715-345-5250 Website: www.ploverwi.gov STAFF REPORT TO: Springville Pond Management Committee FROM: Karmen Anderson, Village Planner RE: Springville Pond 2027 Treatment Proposal DATE: July 15th, 2026 (SPMC) Background Last Fall, the Committee and the Village Board approved the Springville Pond Aquatic Plant Management Plan (APM). This Plan serves as a guide for future management and treatment of the Pond. In order to implement the Plan, Village staff have looked into treatment options for the Pond to address areas of concern. The treatment proposal for review is from Lake and Pond Solutions, LLC. The Village has worked with this company in the past and has had good results. The proposal considers herbicide treatment to target abundant growth of EWM and CLP in the east and west ends of the Pond (~9 acres of treatment area). The areas outlined for treatment align with the APM Plan designations and the prior surveying (see attachments). The goal is to suppress further growth of invasives that can cause navigational issues as well as create dense mats that foster algae. Costs are included in the proposal and total around $12,283 for both treatments (there would also be costs associated with service fees and permitting). Funding would be incorporated into the Village’s budget. The recommended treatment uses ProcellaCOR (Florpyrauxifen-Benzyl). The chemical fact sheet is included in the attachments. There are no recreational restrictions and is non-toxic to freshwater fish, amphibians, birds, bees, and mammals. There are no hazard concerns to human health as well. A waiting period of up to 2 days exists for water used for non-agricultural irrigation post- treatment. Native species that may be affected that are present in the Pond include White Water Crowfoot and Coontail. Overall, ProcellaCOR is selective to target invasives while minimizing impacts to natives. It is not recommended to repeat usage of the same herbicide each year so as to avoid herbicide-resistant plants; therefore, what we decide to use in the future may change. It is important to note that the final approval of any treatment permit is at the discretion of the DNR. Staff is looking for a recommendation from the committee on moving forward with what is proposed by Lake and Pond Solutions, so we can budget accordingly for next year. Recommendation: Staff recommends approval of the ProcellaCOR treatment.

Plover, WI 54467 Scott, Please see updated proposal for Springville Pond for 2027 Management Season. BASIC SERVICE FEES/STANDARD LABOR RATES Please note that we charge a basic service fee for all trips to the property that are not included below. This fee is based on the distance from our Greenville location. For this site, the basic service fee is $125.00. Our standard labor rate for a biologist is $180 per hour, with time billed to the nearest ¼ hour. --2027-- WDNR PERMIT AND PUBLIC NOTICE Lake and Pond Solutions, LLC has secured statewide WPDES coverage for our customers. The DNR state permitting fee is $20 plus $25 per acre up to 50 acres while we charge $60 to complete the permitting process. Based on the 2026 Meander survey, we would be permitting 9 total acres on Springville Pond. A public notice also needs to be run in the most widely distributed periodical. We can handle submitting the public notice on your behalf which would add $75. This treatment would also require large scale treatment application, which would add $270. $650.00 *PLEASE NOTE: We will send you a copy of the permit application to post on your website (or to physically mail). As an applicant you must inform residents where they can find a copy of the permit application (this is part of the mailing that you’ll need to send out). That mailing should also alert all riparian owners where additional information related to the treatment including the approximate date of treatment and irrigation restrictions can be found. You would also be responsible for making copies of the treatment signs and providing a crew to post them prior to treatment (we can also provide a quote for this if needed). SPRING AQUATIC VEGETATION MEANDER SURVEY ESTIMATE We are recommending a spring meander survey for the 2027 season to survey for and document invasive Eurasian watermilfoil (EWM) and curly-leaf pondweed (CLP) growth and expansion. This survey (920) 757-9447 www.lakeandpondsolutions.com josh@lakeandpondsolutions.com Lake and Pond Solutions, LLC would also give us the ability to identify native plant species and species that are or may become nuisance level and may require treatment. Typically, this survey should be done between mid-May to early June, the 2026 survey was conducted 05/15. During this Spring survey, we meander in and out of the entire waterbody marking locations of EWM and CLP with a Garmin GPSMAP64 unit. A Lowrance Elite FS-9 sonar unit is used to locate potential deeper beds of plants. Double headed rakes on poles or ropes are used to confirm species. We would provide two biologists to informally survey the lake and estimate that it will take approximately 1.5 hours ($180/biologist/hour). Additionally, 1 hour of labor is included for map/data preparation. BioBase vegetative mapping is also performed during this survey at an additional cost of $350.00. It should be noted that depths below 1.2 feet are not sufficient for bathymetry mapping and depths below 2.4 feet are not sufficient for vegetation outputs. BioBase mapping is extremely helpful in providing a heat map layer representing vegetative height while also providing highly accurate volume calculations to refine treatment recommendations. After the survey, you would be provided with maps of our invasive species detections (if any), as well as possible proposed invasive or nuisance native plant treatment areas on a Google Earth overlay. The cost below includes our $95 Basic Service Fee. $1,195.00 HERBICIDE TREATMENTS Golden Sands identified the presence of Curly-leaf pondweed (CLP) and Eurasian watermilfoil (EWM) within the waterbody. At this time, neither species is creating navigational issues, and no monotypic stands were observed, although they were recorded as “abundant” in two areas totaling approximately 7.5 acres. Treatment approval is subject to the final determination of the Wisconsin Department of Natural Resources (DNR). Based off the Golden Sands Report, they recommend a west treatment area and east treatment area with the middle being harvested. After our 2026 survey, results showed very similar to their findings from their 2024 report. Main differences were less CLP overall (only 3 plants observed) and a larger EWM presence in the west end. Updated treatment areas along with pricing for said areas. (920) 757-9447 www.lakeandpondsolutions.com josh@lakeandpondsolutions.com Lake and Pond Solutions, LLC TREATMENT AREA 1 (3.089 Ac)–EWM I would recommend using ProcellaCOR for these treatments. Given 26.758 ac-ft that need to be treated at a 3PDU/Acre rate, the cost is below: $6,979.83 TREATMENT AREA 2 (5.1 Ac)– EWM I would also recommend using ProcellaCOR for this area. Given 20.298 ac-ft that need to be treated at a 3PDU/Acre rate, the cost is below: $5,303.95 **Our applications rates are $1,050 for the first five acres and $100 for each additional acre.

Formulations Florpyrauxifen-benzyl is a relatively new herbicide that was first registered with the U.S. EPA in 2017. The active ingredient is 4-amino-3- chloro-6-(4-chloro-2-fluoro-3-methoxyphenyl)- 5-fluoro-pyridine-2-benzyl ester, also identified as florpyrauxifen-benzyl. Florpyrauxifen-benzyl is labeled for control of submerged, floating and emergent aquatic plants using surface, subsurface or foliar application in slow-moving and quiescent waters. Commercial formulations approved for aquatic use in Wisconsin include ProcellaCOR™ EC*. Aquatic Use and Considerations Florpyrauxifen-benzyl is a systemic herbicide (i.e., it moves throughout the plant tissue). It is a WSSA Group 4 herbicide, meaning that the mechanism of action is by mimicking the plant growth hormone auxin and causing excessive elongation of plant cells, ultimately killing the plant. Affected plants may show atypical growth patterns (e.g., large and/or twisted leaves, stem elongation), and leaf and shoot tissue may become fragile. While initial effects will become apparent within a few days after treatment, it will take two to three weeks for the full plant decomposition process to occur. Florpyrauxifen-benzyl should be applied to plants that are actively growing; mature plants may require a higher concentration of herbicide and a longer contact time compared to smaller, less established plants. It is important to note that repeated use of herbicides in the same WSSA group (i.e., with the same mechanism of action) can lead to herbicide-resistant plants, even in aquatic * Product names are provided solely for your reference and should not be considered exhaustive nor endorsements. environments. In order to reduce the risk of developing resistant genotypes, avoid using the same type of herbicides year after year, and utilize effective integrated pest management strategies as part of any long- term control program. Florpyrauxifen-benzyl has relatively short contact exposure time (CET) requirements (typically 12 to 24 hours). The short CET may be advantageous for localized treatments of submersed aquatic plants, however, the target species efficacy compared to the size of the treatment area is not yet known. In some Wisconsin lakes impacts to target and non- target plants have been observed in areas beyond the targeted treatment areas, and research is ongoing to better understand the herbicide’s dissipation and degradation patterns across various lake types. Florpyrauxifen-benzyl is labeled for control of invasive Eurasian watermilfoil (Myriophyllum spicatum), hybrid watermilfoil (M. spicatum x sibiricum) and yellow floating heart (Nymphoides peltata)†. Native species listed on the product label as susceptible to florpyrauxifen-benzyl include coontail (Ceratophyllum demersum), variable-leaf watermilfoil (Myriophyllum heterophyllum), watershield (Brasenia schreberi), and American lotus (Nelumbo lutea)†. Preliminary results from pre- and post- treatment monitoring conducted on a subset of Wisconsin lakes observed negative impacts to dicot species such as northern watermilfoil (Myriophyllum sibiricum), white water crowfoot (Ranunculus aquatilis), water marigold (Bidens beckii), & coontail following treatment. † May vary by formulation, application rate, and/or product. Every product label must be carefully reviewed and followed by the user.

There is a short waiting period (dependent on application rate) for other non-agricultural irrigation purposes. Treated water should not be used for livestock drinking water or for agricultural irrigation†. Herbicide Degradation, Persistence and Trace Contaminants Florpyrauxifen-benzyl is short-lived, with a half-life (the time it takes for half of the active ingredient to degrade) of four to six days in aerobic aquatic environments and two days in anaerobic aquatic environments. Florpyrauxifen-benzyl in water is subject to rapid breakdown by light (photolysis), with a reported photolytic half-life of approximately two hours in surface water when exposed to sunlight. In addition, the herbicide can convert partially to an acid form via breakdown by water (hydrolysis) at high pH (greater than 9) and higher water temperatures (greater than 25°C). Microbial activity in the water and sediment can also enhance degradation. Florpyrauxifen-benzyl breaks down into five major degradation products. These materials are generally more persistent in water than the active herbicide (with a half-life of up to three weeks), but four of the five products are minor metabolites detected at less than 5% of applied active ingredient. Florpyrauxifen-benzyl has a high soil adsorption coefficient (KOC) and low volatility, which allows for rapid plant uptake resulting in short exposure time requirements. Florpyrauxifen-benzyl degrades quickly (two to 15 days) in sediment. Few studies have yet been completed for groundwater, but based on known environmental properties, florpyrauxifen-benzyl is not expected to be associated with potential environmental impacts in groundwater. Impacts on Fish and Other Aquatic Organisms Florpyrauxifen-benzyl is practically nontoxic to freshwater fish and invertebrates, birds, bees, reptiles, amphibians and mammals. Florpyrauxifen-benzyl will temporarily bioaccumulate (the process by which chemicals in the environment or in a food source are taken up by plants or animals) in freshwater organisms but is expelled and/or metabolized within one to three days after exposure to high (greater than 150 parts per billion) concentrations. Human Health There are no risks of concern to human health since no adverse short- or long-term effects, including a lack of carcinogenicity or mutagenicity, were observed in the submitted toxicological studies for florpyrauxifen-benzyl regardless of the route of exposure. Drinking water exposures to florpyrauxifen-benzyl also do not pose a significant human health risk. Additionally, there is no hazard concern for metabolites and/or degradants of florpyrauxifen-benzyl that may be found in drinking water, plants and livestock.
