Minutes Discussion and possible action on the following minutes: A. Approval of Minutes of July 8, 2026 Regular Meeting Hearing no revisions or objections from the committee members, Chair Hausman approved the minutes from the July 8, 2026 regular meeting. 5. Citizen Comments Seeing no one who wished to speak, citizen comments were closed at 6:02 p.m. 6. Unfinished Business Discussion and possible action on the following items: A. “Welcome to the Lake” Program No report. B. Nagawicka Lake Water Level and No-Wake Rules Tom Hafner, City Administrator/Director of Public Works, was present to speak. Hafner said what should be considered for setting a slow-no-wake elevation are the erosion concerns. Hafner said a concern he has in regard to changing the elevation is balancing the needs of people living upstream and downstream, and mitigating the dam. Hafner said in the last 20 City of Delafield Lake Welfare Committee Minutes August 12, 2026 Page 2 of 3 Office: (262) 646-6220 - E-Mail: cityclerk@cityofdelafieldwi.gov – www.cityofdelafieldwi.gov years, under the 10 inch slow-no-wake elevation, slow-no-wake has gone into effect 3 times. To look at the same data set over 20 years, if an 8 inch slow-no-wake elevation went into effect, there would be 5 instances and those periods would last 50 percent longer than with a 10 inch slow-no-wake elevation. Hafner said under current circumstances, for 10 inches they would be able to get back down to slow-no-wake within a week and if it goes to 8 inches it would be a week and a half to get back down. Hafner said the city will be creating a Facebook page for the City of Delafield dam once the lake level meter is fixed. Hafner said that is where updates will be posted regarding the dam and the lake levels. The committee decided to revisit this topic if there are more occurrences. C. Erosion / Storm Runoff from the East Side of Nagawicka Lake Hafner said Common Council approved staff to move forward with the effort and cost of pursuing easements from the three property owners involved. Hafner said it is looking like it will be a stabilization project using rock or riprap and possibly vegetation planting with two of the easements. Hafner said they will apply for a DNR grant for the project and they are looking at best case scenario 2028-2029 for construction. Hafner noted they have debunked the concern that the runoff was coming from the Nagawicka Heights neighborhood. Hafner said from an engineering perspective, the city believes the runoff is not coming from Nagawicka Heights. D. Wake Surfing Recommendations and Notifications Hausman said he has received a couple of wake surfing complaints. Hausman noted it is an uphill battle regarding regulating wake surfing through an ordinance because of the enforcement issue. E. Aerators Hafner said state laws allow aerators and he is concerned about the city’s authority to regulate the aerators. Hafner suggested consulting the city’s attorney before the committee would move forward with this topic. The members agreed to table this topic until next summer so they can see how much of an issue this is. In the meantime, committee members can give notice to residents that are creating open water due to aerator use. F. Annual Lake Awareness Meeting Date, Location, and Agenda Agenda items discussed for the Lake Awareness Meeting were boater safety, topic roundup, slow-no-wake rules, weed treatment and harvesting, winter aerators, starry stonewort, and wake surfing. Ellsworth volunteered to present on agenda topics if needed. 7. New Business Discussion and possible action on the following items: A. Weed Harvesting on Nagawicka Lake Ryan Chrapla, 616 Maple Avenue, Waukesha, WI, was present to speak. Chrapla is a machine operator for the city that works on the lake. Ryan said the number of weeds they pull from the lake fluctuate and the end of the year for weed harvesting is around September: • As of August 6, 2026 they have taken out 1,185 cubic yards. City of Delafield Lake Welfare Committee Minutes August 12, 2026 Page 3 of 3 Office: (262) 646-6220 - E-Mail: cityclerk@cityofdelafieldwi.gov – www.cityofdelafieldwi.gov • As of August 6, 2025 there were 1,115 cubic yards and by September 2025 there were 1,630 cubic yards. • As of August 6, 2024 there were 740 cubic yards and by September 2024 there were 1,320 cubic yards. • As of August 6, 2023 there were 1,040 cubic yards and by September 2023 there were 1,665 cubic yards. • As of August 6, 2022 there were 640 cubic yards and by September 2022 there were 1,070 cubic yards. Hausman noted the city is not obligated to clear out the weeds on the lake and it is a service the city provides that should be appreciated. The committee members thanked Chrapla for the service they provide. B. Aquatic Invasive Species – Starry Stonewort in Nagawicka Lake Hausman reported the WDNR found starry stonewort off the end of the Bleeker Street launch ramp. Hausman said starry stonewort has been reported in most surrounding lakes and has only been a real problem at a couple of the lakes. The WDNR only recommends active management when it tops out and they are not recommending the city does anything about it this year. Long term, the WDNR will do a survey and it will be part of an update to the aquatic plant management plan. Hausman said they can apply for grants to help with the cost of the surveys needed. C. Review and Acknowledge the Recommended Ordinance Amendment and Associated Signage for St. John’s Public Pier Alderman Stephen Laughland, Chair of the Park & Recreation Commission, discussed the recommended ordinance amendment to Common Council that was included in the ePacket. Motion by Jerry Dunnick, seconded by Jim Ellsworth, to recommend to the Park & Recreation Commission, and therefore to Common Council, to support the recommendations made originally by the Park & Recreation Commission. All in favor. Motion carried. 8. Requested Future Agenda Items Note: No discussion on requested items A. “Welcome to the Lake” Program B. Wake Surfing Recommendations and Notifications C. Erosion / Storm Runoff from East Side of Nagawicka Lake D. Aerators E. Nagawicka Lake Water Level and No-Wake Rules F. Aquatic Invasive Species – Starry Stonewort in Nagawicka Lake 9.
