LDLD Q2 2024 Newsletter

Here are the 2nd quarter updates and a few safety reminders from the LDLD Board of Commissioners.  Enjoy the summer and safe boating everyone!

Boating Safety

Safety is a top priority for both lake residents and our guests. Please be courteous and respectful to fellow lake users.  Remind your guests that this peaceful, family lake practices safe boating.  As a community, we expect respectful behaviors from everyone for the benefit of all.  Now is a good time to refresh yourself, and inform family and friends, of the City of Muskego and WI DNR Boating Laws and Requirements including but not limited to:

  • When skiing or tubing, travel in a counterclockwise direction

  • If born after January 1, 1989, the completion of a boater’s safety course is required to operate any motorized boat including personal watercraft. 

  • Slow-no-wake speed requirements:

    • Within 150 feet of any dock, pier, or buoyed restricted area

    • From sunset until 8:00a.m. the following morning

  • Specific for Personal Watercraft:

    • Slow-no-wake speed within 100 feet of a pier, raft or another watercraft

    • May not be operated between sunset and sunrise

  • Navigation lights: 

    • Red/green sidelights & a masthead or all-round white light, are required from sunset to sunrise. 

    • No other lights, including docking lights, may be used, while out on the lake, which could be mistaken or interfere with the required lights.

Mechanical Weed Harvesting Project

Our “mechanical harvesting” permit was approved and is valid for 5 years (2023 to 2027).  Midwest Aquatics did conduct Curly-Leaf Pondweed(CLP) and Eurasian Water Milfoil(EWM) harvesting activities on Lake Denoon the week of May 20 to 24 and May 28 to 31.  A total of 192 cubic yards of weeds were removed from the lake. Weeds Harvested- E.Milfoil (90%), Curly Leaf Pondweed (40%), Common Pondweed (6%), Chara (2%), Pondweed (1%) and other weeds (1%). The harvester could not get in-between piers and needs to operate in 3+ feet of water. Also, per the DNR guidelines, a patch of weeds must be >50% CLP and/or EWM for the harvester to cut that area  This constrains what can be cut particularly in the corners/bays.  Therefore, they were not able to get to all infested areas.  Midwest Aquatics is expected to conduct additional weed harvesting sometime later this summer.

Fish Stocking

In 2024, the Lake District received a generous donation offer from the family of Cindy & Ken Jensen and Bob Kargl, to provide fish stocking.  Along with additional funds from the LDLD, the lake district will utilize the money donated to stock the lake with Black Crappies at the end of September/early October.   The DNR is expected to stock Walleyes in 2024.

ProcellaCOR Weed Treatment

The DNR permit for ProcellaCOR to treat Eurasian Watermilfoil was submitted and approved by the DNR on April 11.  An agreement was made with Solitude Lake Management and Brian Suffern applied the chemical on Monday, June 17.  This product mimics a hormone that affects EWM, and a few other species, but to a lesser extent. It is preferred by the DNR as it is designed to protect native plant species.  It makes EWM grow so rapidly that it grows itself apart.  Riparians are encouraged to maintain and rake their shoreline, if you can, to help remove weeds.

Sub-Point Intercept Survey

The two Sub-PI Aquatic Plant Surveys will be conducted on July 11 and August 22, 2024.  This activity is another part of our SSW Project Plan.  Amanda Schmitz, DNR Aquatic Invasive Species Coordinator, and others, will utilize the Hart Drive boat launch starting around 9am.

They will be using a DNR boat equipped with GPS/sonar and will sample about 60 points around the location where SSW was found in August of 2022(waypoint 396).  

The DNR will create a 2nd sub-PI grid in the vicinity of the Hart Drive launch.  The DNR will also do “spot checks” in two new areas: around waypoint 265, near the wetlands in the southwest bay area and in the Denoon Park boat launch.

These surveys will take a full day to complete.  The DNR will pull their vehicle and trailer out of the Hart Drive launch and park along Hart Drive.

Clean Boats Clean Waters (CBCW)

The LDLD CBCW watercraft inspection program started at the Denoon Park and Hart Drive boat launches in May.  Inspectors have been hired, completed their training and are scheduled to cover weekends throughout the summer. Boat inspectors perform boat and trailer checks, hand out informational brochures and educate boaters on how to prevent the spread of aquatic invasive species.  Data is collected and entered into the DNR statewide database.  This program is made possible by a 75% DNR matching grant.

Lady Gliders

The Lady Gliders is a casual get together of the women on Lake Denoon on Wednesday mornings at 08:30 AM.  Please join us whenever you can as we kayak, paddle boat or paddle board around the lake. Just head out to the middle of the lake to find the group which starts at the gray boathouse on the east shore behind Coaches.

LDLD Annual Membership Meeting

Mark your calendars for Monday, August 26, 2024.  The official announcement, location and agenda will be sent via USPS to all LDLD members in early August.
