The Aquatic Plant Management (APM) Committee is responsible for managing the aquatic plant growth, both invasive and indigenous, throughout the waterway. We will clearly communicate to the WWMD board and owners through monthly board meetings, regular reports and updates to this website. Click here to see the latest meeting minutes, which include committee reports.

Aquatic plant conditions change on a continuous basis. Effects of the seasons, floods, droughts, heat waves and dam levels affect the aquatic plant population in different ways. It is the role of this committee to explore, recommend and implement the use of all appropriate approaches possible to manage these changing conditions in a cost effective manner.

Summer Aquatic Plant Management Update

June 18, 2020 – All forms of weed removal and control on the waterway are now underway. Wisconsin Lake and Pond Resource (WLPR) has concluded their first round of navigation lane treatments and they are reporting great success with the treatment this year.

We do have an increasing problem with both Eurasian Water Milfoil (EWM) and Curly Leaf Pondweed (CLP). The areas with extensive growth are noted in the maps below. The CLP growing season ends shortly and the weeds should begin to die back at the end of June in to the beginning of July.

The EWM is best treated at the beginning of the season when it is most susceptible to the use of the chemicals. Treating it now would result in partial mitigation of spread but would also likely lead to increased algae blooms due to the increased decaying biomass in the water. We will either need to treat the areas noted in the maps in early 2021 at considerable cost to the district, or we need to continue to explore the possibility of the EcoHarvester. The harvester remains a viable option if we get approval from the DNR for its use. Both the DNR and WLPR agree that treatment at this time would be a poor use of district funds.

Tichigan Lake – mainly EWM and lots of it, especially in the north end. Areas inside the red lines are EWM. There is probably quite a bit more, especially along the west shore and southern half of the east shore, but these areas were not checked.

Buena Lake – dense CLP topped out throughout. The area north of the line is a mix of CLP and EWM. South of the line the EWM drops out and is replaced by native species. There’s still some, just not nearly as much or as dense.

Waterford Lake and Elm Island Bay – primarily EWM. There was some in Island View Bay, but it wasn’t the main problem.

Mechanical Harvesting is beginning this week and we will harvest as much as possible from the areas noted in the Lake Management Plan, and we will use the harvester where we can to make navigation lanes in the areas with heavy EWM and CLP growth.

DASH began their work last week. Dan Schultz and Riese Aquatics have done a great job clearing the Willow Court and White Oak Lane sites. Riese will be off the water this week but they will begin again next week and will stay until all of their sites are complete.

APM Committee Spring Update

April 4, 2020 – As we move into 2020 the Aquatic Plant Management Committee has undergone some changes. The previous commissioner Steve Larry has stepped down from the Commissioner position and is going to serve the district in a supervisory role monitoring the progress of Herbicide application. He will also provide support to our new Commissioner Chad Buchaklian.

While we are all doing our best to stay isolated and slow the spread of COVID-19, the APM Committee is busy working to ensure that we stay on top of any Aquatic Plant issues and we are working to have everything organized for the upcoming season. We spent the winter soliciting bids for Aquatic Invasive Species control (AIS), Navigational Lane Application, Diver Assisted Suction Harvesting (DASH), and Weed Harvesting. After a very thorough vetting and bidding process we have agreements with vendors for all of the above projects.

Wisconsin Lake and Pond Resource will continue to be our vendor for AIS and Navigational Lane herbicide application. They are the company we have been using, and they ended up being the most competitive bid again this year. They come to the District with a plethora of experience and first hand knowledge of the lake and the problem areas. Informational post cards have been sent out regarding the treatments, and we will post updates on the web page with the timing of applications, and they will post notices on piers when they have treated the area. Permit applications have been submitted to the DNR and we plan to begin treatments for AIS in April and Navigational lanes shortly thereafter. Please note, if you do not wish to have the area around your pier treated please contact Chad Buchaklian at 262-957-0437 or to opt out of the applications.

Riese Aquatics will be doing the D.A.S.H. (Diver Assisted Suction Harvesting) program this summer. Riese comes to the district with a very long list of highly satisfied clients and they are very eager to get to work. They also went through a stringent vetting process and provided the District with the most competitive bid. We look forward to working with Brandon and the team at Riese this year.

Finally, the District has a new vendor for our harvesting program. Midwest Aquatics also provided us with the most competitive bid and provided the District with a great referral list as well as a high recommendation from the DNR. Midwest Aquatics has two harvesters, both of which are larger than the previous vendors harvester. They will be able to cut and remove weeds at more than twice the speed of the previous vendor saving riparian owner money and increasing the efficiency with which we get the project completed. We look forward to working with Dave at Midwest Aquatics this year.

While we have all been in a bit of a lockdown, the committee has been busy and we plan on moving ahead just like any other year. We anticipate a great season on the lake and we look forward to seeing all of you out on the water. If any riparian owner have any questions or concerns please do not hesitate to reach out to Chad Buchaklian at 262-957-0437 or and he will be sure to address the issue at hand. Stay safe, healthy, and we will see you all on the lake.

Starry Stonewort

A new invasive species, Starry Stonewort, has been detected in some local lakes. This species has been known to cause nuisance conditions in Michigan, New York and Indiana but is new to Wisconsin. Our waterway has been surveyed and none has been detected. Our Clean Boats/Clean Water program is checking boats at the Library Launch and we have no reports of any being found.

The information we have received from the WI DNR clarifies that Starry Stonewort does not kill fish and the lake will not ‘die’ if this plant becomes established. However, it can affect the aquatic plant community and alter the aquatic habitat in the waterway. We will include Starry Stonewort in our pre- and post-season surveys and if it were to be found it will be included in our Lake Management plans.

Flowering Rush Found in Our Waterway

During the herbicidal treatment done on June 2nd, 2016 we identified a new Invasive Species in our waterway. The WDNR was with our treatment provider and confirmed that we have a small amount of Flowering Rush growing in some areas of the shore line. When caught early, this is easy to remove with hand pulling. Wisconsin Lake and Ponds Resource (WL&PR) is recommending a full survey with hand pulling being done at the same time. This work is covered by a WDNR Rapid Response grant. Attached here is the grant application.

The committee will continue to explore new approaches and adjust how we implement the current techniques. We are always open to input and feedback, if you have heard of other tactics, please feel free to let us know.
